On June 17, 2022, the world's first 35kV high-voltage direct coupled energy storage system developed by NR was successfully connected to the grid in Shaoxing Hongxu energy storage power station in China. It not only helps to achieve the efficient use of clean energy and promote the green and low-carbon transformation, but also enhances the flexible regulation capacity of the power grid. High voltage direct coupled energy storage not only reduces the electrical distance from the main grid, but also has the advantages of stronger grid support effect, response consistency and higher conversion efficiency. Energy storage batteries The smooth operation of the project helps to explore and establish the standard of advance energy storage technology, promote the energy storage system to move towards a higher voltage level, larger capacity, safer, more reliable and more efficient direction, and can adapt to the characteristics of multiple types of energy storage batteries, making a useful attempt for the development direction of energy storage. The whole system uses a cascade topology to distribute the batteries to each PCS module The whole system uses a cascade topology to distribute the batteries to each PCS module. The reliability of the whole energy storage system is effectively improved through the integrated closed self-circulation air cooling technology and online thermal redundancy technology. At the same time, the multi-level active equalization technology is used to greatly improve the utilization of the battery and eliminate the "short board effect" of the battery cluster. Green power systems NR has provided a complete set of solutions for Shaoxing 35kV high voltage direct coupled energy storage system, including energy management system (EMS), Power Management System (PMS), high and low voltage full series air / liquid cooled Power conversion system (PCS), and battery management system (BMS). NR will continue to do a good job in the exploration of new energy storage systems, promote the research and practice of grid-forming energy storage application, and make more contributions to the construction of green power systems.

On June 8, 2022, NR controlled switching device was successfully put into operation in Fengning pumped storage power station with the largest installed capacity in the world, which successfully ensured that the pumping and storage power station units were connected to Zhangbei flexible DC power grid. This is the first application of NR's controlled switching device in a large-scale pumped storage project. Fengning pumped storage power station is a key project serving the Beijing Winter Olympics to achieve 100% green power supply. It is the first time that the pumped storage power station connected to the flexible DC power grid, which provide a valuable solution to solve the problem of large-scale development and utilization of renewable energy. Transformer charging excitation Fengning pumped storage power station is known as the world's largest "super power bank", close to the core area of the 10 GW wind power base. The power station is equipped with 12 units, with a total installed capacity of 3.6 GW, an annual saving of 480,000 tons of standard coal and a reduction of 1.2 million tons of carbon dioxide emissions. NR has cooperated with customer to discuss the issues of main transformer charging excitation In order to reduce the impact of the main transformer switching of Fengning Pumped Storage Power Station on the flexible DC system in Zhangbei, NR has cooperated with customer to discuss the issues of main transformer charging excitation inrush current and voltage harmonics, and proposed a solution for adding controlled switching device on all 500kV transformer sides circuit breakers of pumped-storage power stations. Main transformer switching In order to meet the complex "pumped storage + flexible DC" excitation inrush current suppression requirements, NR has comprehensively considered factors such as the harsh working conditions of two main transformers in parallel, the mechanical dispersion of circuit breakers, transformer parameters, and remanence level. Before the main transformer was officially put into operation, a large amount of test data was collected, and simulation calculation research was fully carried out. The main transformer switching test of 1, 2, 9 and 10 units successfully suppressed the maximum inrush current from more than 1000A to less than 300A, effectively reducing the busbar voltage distortion and system harmonic content. The pumped-storage power station can be reliably integrated into the flexible DC grid under the impact disturbance of the main transformer switching. Advanced power system With the construction and development of an advance power system with a high proportion of renewable energy and power electronic device connected to the grid, the need for grid stability to suppress harmonics and disturbances has become prominent. As an important technical means to mitigate transient shocks, controlled switching technology will also face more opportunities and challenges. NR will continue to develop high-quality product and solution to make more efforts for power system reliability and flexibility.

Fleet electrification provides opportunities to achieve climate goals while delivering social, financial, and environmental benefits to individuals, businesses, and communities, but the road to successful EV implementation is not without obstacles. Your EV fleets need to work — all the time under varying conditions — to ensure optimal uptime while maintaining energy efficiency. Consequently, electric vehicle service equipment (EVSE) can’t just be “tacked onto” your existing operation. Rather than a “new standalone addition,” it requires a thoughtful and forward-looking approach to seamlessly integrate into your overall facility. Ensuring the type of reliable power needed for an electrified fleet is critical. Luckily, there are a number of new and emerging solutions that promise to deliver clean and reliable local power generation. The Challenges The availability and reliability of the power needed to support electrified fleets is a primary roadblock for many commercial fleet operators. It’s important to look at where that power comes from, how much it will cost, and whether it will be available when needed. Projections indicate that the demand for electricity will surge by 50% during the next two decades Today’s energy landscape is complex. Projections indicate that the demand for electricity will surge by 50% during the next two decades, with no signs of slowing down. According to Grid Strategies, the U.S. electric grid is not prepared for this level of significant load growth. The sheer amount of power needed to keep trucks charged and running 24/7 can be substantial. This poses a key risk for reliability in EV infrastructures, particularly in mission-critical situations. In addition, most fleet operators have become accustomed to fairly predictable fuel costs, since many take advantage of long-term supply arrangements. By contrast, electricity grid costs can vary and result in unpredictable spikes. This adds an extra layer of complexity when it comes to the planning and timing of fleet charging. As a result, many fleet charging operations are turning to local power generation. Intelligent Microgrids, the Energy Insurance Microgrids are nothing new, with rural communities relying on them for decades. Increased affordability and shifting regulations are allowing for more of these microgrids to be powered by renewable energy methods. A common misconception is that microgrids can completely off-set power from the grid. In reality, they are designed to provide peak load shaving and system resiliency. Coupled with an EV infrastructure, microgrids can offer more flexible and reliable energy management. When compared to a traditional microgrid for a building system, microgrids for fleet electrification present new challenges. Most notably, microgrids for fleet electrification are not modeled on an existing load, but rather anticipated demand, which can make reliable load-based modeling more difficult. However, an "intelligent" microgrid uses control systems to manage, store, charge, and discharge energy across the system. Strategic energy management The system can buy power from the grid during low-cost periods while storing self-generated solar power These controls monitor supply and demand, track real-time electricity prices, and create efficient charging schedules, considering factors like Time of Use (TOU) and peak day rates. For example, when electric fleets plug in, demand may increase significantly overnight, making strategic energy management crucial. The system can buy power from the grid during low-cost periods while storing self-generated solar power for later use. When prices rise, it discharges stored energy, keeping costs stable. It can also operate independently, ensuring continuous power during outages and disruptions, improving efficiency, cost control, and reliability. Conversely, fleets often permit charging flexibility within defined boundaries, providing a unique dispatchable resource that can be tuned to fit the needs and energy resources of the customer. A New Category of Local Power Generation Linear generator technology is proving to be an innovative solution for EV infrastructures by providing flexible, resilient and cost-effective on-site base load power. Linear generator technology provides fuel-flexibility meaning they can directly run and switch among traditional fuels like natural gas or propane. Or, they can use low and zero-carbon fuels such as RNG, biogas, hydrogen, and ammonia. Its backup capabilities ensure power through hurricanes, sub-zero snowstorms, excessive heat, and other extreme conditions. Based on capex and operating costs, linear generators can provide a competitive levelized cost of ownership compared to grid power or other alternatives in certain regions. Net-zero goals These solutions allow for flexibility and integration of new fuels as they become available The technology can also be quickly deployed at scale, which is ideal for large fleet operators looking to quickly and cost-effectively deploy resilient EV charging infrastructure while reducing emissions and working toward net-zero goals. What’s more, linear generators deliver a more “future-proof” path. While the dominant sources of fuel for local power generation today is well understood, new and exciting fuels are on the horizon. These solutions allow for flexibility and integration of new fuels as they become available. All without having to replace or retrofit existing equipment. Experts Will Power the Future As companies look to integrate EVs into their operations, a well-thought-out plan for infrastructure is essential to ensure safety, reliability, and long-term success. The integration of onsite power systems will play a critical role in optimizing energy use, lowering costs, and maintaining system resilience. The good news is that energy management is becoming more flexible, ensuring that fleet electrification is not only sustainable but also cost-effective. To ensure a seamless transition and maximize the benefits of fleet electrification, many companies will be moving forward by working with experienced consultants and planners to create a future-proof infrastructure that meets both operational and environmental goals.

The promise of electric vehicles is closer to reality than ever before. New plans and investments at the federal level designate billions of dollars to move our country toward clean energy, including $2 million to help auto manufacturers retool facilities to increase EV production. Additionally, the Biden Administration has announced a goal to create 100% carbon-free electricity by 2035 and a net-zero carbon economy by 2050. Domestic EV marketplace The domestic EV marketplace has grown from 16,000 to more than 2 million vehicles in the last decade and is poised to expand at lightning speed over the next ten years. S&P Global mobility has predicted that by 2030, electric vehicles (EVs) will make up 40% of the U.S. market share of new vehicles on the road. This dramatic increase in EVs will require a nationwide network of charging stations to meet the demand from the current 140,000 to over 1.1 million. Charging stations It is a necessity that regulators lay the groundwork now for a reliable and secure charging networkThe expansion of charging stations will undoubtedly give zero-emissions drivers more confidence in their ability to refuel more conveniently. Still, it’s critical that confidence in infrastructure security also be prioritized alongside this growth. If not adequately protected and monitored, charging stations could serve as access points for cybercriminals, potentially leading to personal data leaks, attacks on vehicle systems, and even widespread blackouts. As EVs continue to gain momentum as realistic alternatives to CO-2 emitting vehicles, it is a necessity that developers and regulators lay the groundwork now for a reliable and secure charging network for the long term. EV Charging Infrastructure and the electric grid The nation’s electric grid generates and delivers electricity essential to everyday life. It’s made up of power plants and other sources of generated electricity, complete with transmission and distribution lines and infrastructure that delivers essential power. Grid connection An important aspect to remember about EV charging stations is that they connect to their relative electric grid. Simply put, the infrastructure for charging stations is comprised of devices that wait for another device to connect and communicate. However, it lacks a third-party firewall or other devices that can act as protection. Unfortunately, this results in vulnerability and means new doors for cybercriminals to walk through. Cybersecurity risks If the grid became compromised by a large-scale attack, it could lead to destructive and widespread blackouts Even before EV charging stations are factored in, the electric grid faces substantial cybersecurity risks from criminals, terrorists, hackers, and foreign governments every day. If the grid became compromised by a large-scale attack, it could lead to destructive and widespread blackouts that would undoubtedly affect EV charging stations and other essential institutions such as banks, hospitals, and gas stations. With the expansion of EV charging stations, the risks only grow. Now is the time to address threats and strategize before disaster strikes. Risks of connectivity emerge The world we live in has reached a level of being almost entirely connected at all times – security systems, appliances, health monitors, industrial sensors, and now, our vehicles. While the connectivity of vehicles has been incredibly beneficial to consumers and the automotive industry alike, the growth in the internet of things (IoT) has opened countless doorways for cybersecurity threats. Software flaws One young information technology security specialist reported finding flaws within a third-party software that a handful of leading EV manufacturers use. It gave him access to more than 25 EVs in at least 13 countries. The man, who stumbled on the findings in 2022, said he could remotely control some EV functions, including starting vehicles, unlocking windows and doors, disabling security systems, and turning on stereo systems and flashing headlights. The IT specialist said he could also tell if a person was in the vehicle. In a separate and concerning situation, a single compromised password led to a foreign-fronted cyberattack on a U.S.-based pipeline in 2021. It halted the fuel supply process on the east coast and cost the company $4.4 million in ransom money. Cyberattacks Thousands of charging stations are already in danger of being targeted by cybercriminals The point is that even massive and powerful companies can fall victim to cyberattacks. Even though cybersecurity is a critical issue for EV manufacturers, their systems are still vulnerable to hackers. Thousands of charging stations are already in danger of being targeted by cybercriminals, and as the number of stations grows, so too will the risk. The higher the number of entry points, the more opportunities hackers will see. If they can break into and gain access to even the most sophisticated EVs, it could be catastrophic. Ensuring security and reliability through proactivity Because charging stations are connected to the country’s primary grid, the entire infrastructure must be armed with the most aggressive security measures. The risks associated with modernized electric vehicles are not something that traditional automotive safety regulations and security standards properly cover. The complicated and rapid evolution of EVs is putting them at a heightened threat. When charging stations are connected to the electrical grid, it is imperative to ensure strong cybersecurity measures are in place to remain dependable and effective.  Embedding cybersecurity technology We often see outside parties utilized to secure tech because of the frequent lack of necessary cyber protection The best way to ensure the electric grid's safety is to build cybersecurity technology directly into the charging stations. We often see outside parties utilized to secure tech because of the frequent lack of necessary cyber protection. Unfortunately, the promising growth EVs and their charging stations bring to our environment also contributes to technology’s vulnerabilities, which can cause key security measures to be overlooked. There’s no getting around it: EV charging stations are highly vulnerable to hackers. Awareness and solutions As the growth continues, there is an acute need for heightened awareness and solutions for the weaknesses associated with these charging stations. These solutions should consider everything from the charging points and devices to operators of the energy distribution networks and infrastructure providers. We must aim to implement advanced cybersecurity measures that will keep safe drivers and all the data that EVs contain.

As the demand for power increases in the UK across growing domestic and industrial markets including the nuclear industry, so the need for reliable power generation, transmission, and distribution using Medium Voltage cables has risen with it. The demands for power has never been greater, with the explosion of development in towns and cities across the UK and the growth of industrial development and technology reliant on consistent supplies. Medium voltage cables As the incidence of non-approved cables continues, Medium Voltage (MV) cables coming onto the market should be independently approved and certified as compliant as the pressure mounts on the installation of quality products in modern building developments. Indeed, new demands are being placed on the grid continually for reliable supplies and the development of nuclear plants at sites including Sellafield and Capenhurst only increases that need for reliable supply using approved products throughout the supply chain. New demands are being placed on the grid continually for reliable supplies The supply chain should be particularly careful around the application of these cables into such high-risk environments as these as well as hospitals, major industrial sites and sub-stations serving infrastructure sites. MV cables are crucial to our infrastructure. Electricity leaves the generating site and is routed via a step-up transformer to take it up to the National Grid distribution voltages of 400Kv, 275Kv, and 132Kv. Once in the local area, the supply goes through step-down transformers that reduce the voltage to 415V with domestic supplies tapped off at 230V. Large volumes of power To facilitate moving electricity around the National Grid, there are almost 4,500 miles of overhead lines, almost 1,000 miles of underground cables, and 342 Grid substations. Once stepped down, power is then distributed on local networks at a lower voltage, commonly 66Kv,33Kv, and 11Kv. In all, there are 14 licensed District Network Operators (DNOs). Very often, the supply of power to consumers of large volumes of electricity is routed via sub-stations to feed large sites such as industrial installations, hospitals, and educational institutions. To provide power to the sub-stations - very often located on the premises of the establishment that they supply - Medium Voltage (MV) cables are used. MV cables were only developed as the level of voltages increased and the need arose for a greater classification range. A developing market The size of the market has developed to the point where the global MV cables market was valued at $39.31 billion in 2016 and is projected to grow at a rate of more than six percent until 2022. The technical design and specification of the cables themselves are of paramount importance within the power distribution network. The AEI Cables range of MV cables meet all requirements of BS6622, BS7835, and IEC60502-2 and are all approved and certified by third-party approval organization BASEC for ranges up to 33kV. There are a number of technical considerations to be taken into account including the size of the installation, the position of the installation in relation to the network, and the presence of primary and secondary sub-stations. Non-approved cabling Prior to installation, a detailed route survey should also be carried out to plan where cables will be joined and to identify any possible obstructions which may require special civil engineering works such as directional drilling. Underlying the critical nature of supplies to these types of services, the incidence of non-approved cables continues, so the application of MV cables into these important and sensitive environments becomes critical. In these environments, it is even more crucial to get it right the first time There have been many instances in the recent past of non-approved cables coming onto the market, but in these environments it is even more crucial to get it right the first time, thereby reducing the risk and the cost of anything going wrong. Look for the British Standard, European or international standard number, the manufacturer’s mark, and third-party approval markings. Even if there are markings, it is worth checking because some labels and stamps have been used fraudulently. Cables can become untraceable Cables that are unmarked but not checked can become untraceable so it is important at the point of receipt for contractors to check every time. Also, keep records of purchase and delivery to ensure that what is being installed is what was specified originally. It is well worth the small amount of time to make these checks, especially as these cables are buried and relied on to provide a continuous power supply. In a number of instances, cables are even being laid under the sea to avoid lengthy and costly delays in seeking permission from landowners. Some cables are provided with an armored layer to help protect them against damage whether installed below or above ground, generally for industrial applications. Armoring also protects a cable during storage, transport to site, and installation. Metallic armoring is always earthed at one or more points in the circuit and may therefore contribute as a protective conductor to carry earth fault current. Extensive testing Modern polymeric-insulated LV and MV cables designed for UK utility use are usually not armored but have a concentric layer of copper wires under the outer sheath. Faults in underground cables are very expensive to repair, especially cables installed under roads and pavements. Repairing a fault will probably involve cutting out a length of cable on either side of the fault and installing a new length together with joints to connect to the existing cable. MV cables are subjected to extensive testing of material components and electrical tests including AC voltage and partial discharge. MV cables are subjected to extensive testing of material components and electrical tests Supplying industries At AEI Cables, we supply products to the construction, industrial, fire protection, defense, mining, and rail industries worldwide meeting the requirements for MV cables to BS 6622 and BS7835 and the highest relevant industry standards including ISO 9001 ISO 14001, and ISO 18001 for ranges up to 500kV. These products are also approved by leading independent approvals organizations nationally and internationally including BASEC, LPCB, and Lloyds. Third-party approval verifies that they can pass rigorous testing in the conditions in which they will operate. The demand continues for MV cables of quality which can consistently supply power to meet the growing challenge in whatever form it is presented.

The electrical industry is expected to have a labor shortage of about 60,000 workers by 2026. A labor shortage in the electrical trade is not inevitable, but it is likely to continue if the industry does not take steps to address the issue. Like other skilled trades, the electrical industry is facing challenges that could contribute to a labor shortage, including an aging workforce, a lack of interest among younger generations, and competition from other industries. However, there are strategies the industry can implement to address these challenges and attract a new generation of workers. These strategies include increasing awareness of the benefits and opportunities of skilled trades, investing in training and education programs, improving working conditions and compensation, embracing technology, promoting diversity and inclusivity, and collaborating among industry, education, and government. Improving working conditions Factors in the current labor shortage in the electrical industry include: Aging workforce: Many workers in the electrical industry are nearing retirement age, and there are not enough younger workers to replace them. This has led to a shortage of skilled workers with many years of experience in the industry. Lack of interest in the trades: There has been a decline in the number of young people pursuing careers in the skilled trades, including electrical work. This is due in part to a focus on four-year college degrees as the preferred career path, as well as a lack of awareness of the benefits and opportunities of skilled trades. Competition from other industries: The electrical industry is competing with other industries, such as construction and manufacturing, for skilled workers. Training and education: Training and education are critical for developing the skills and knowledge necessary for electrical work. However, there is a shortage of qualified trainers and educators. Increasing demand: The demand for electrical services is increasing, particularly in areas such as renewable energy and smart grid technology. Attracting and retaining workers To attract and retain workers, the electrical industry must offer competitive wages and benefits One strategy to address the labor shortage is to increase awareness of skilled trades and to promote the benefits of a career in the electrical industry through outreach programs in schools, career fairs, and other events. Providing access to quality training and education programs that develop the skills and knowledge necessary for electrical work is crucial for attracting and retaining workers. This can be done through apprenticeship programs, vocational schools, and community colleges. To attract and retain workers, the electrical industry must offer competitive wages and benefits, as well as a safe and supportive work environment. This includes offering training and development opportunities, flexible schedules, and opportunities for advancement. Inclusive work environment The electrical industry is changing rapidly, and workers must be equipped with the latest technology and tools to stay competitive. Providing workers with training and access to the latest technology can help attract and retain workers. The electrical industry should actively promote diversity and inclusivity to attract a wider pool of workers. This includes efforts to recruit workers from underrepresented groups and create a welcoming and inclusive work environment. The electrical industry is changing rapidly, and workers must be equipped with the latest technology Companies in the electrical industry are addressing the labor shortage problem by investing in workforce development programs and initiatives. For example, Schneider Electric has developed a comprehensive workforce development program called the Schneider Electric Energy and Automation Training (SEAT) program. The SEAT program provides training and certification for employees, customers, and partners in areas such as energy management, automation, and digital transformation. Developing training programs Siemens has developed several initiatives to address the labor shortage in the electrical industry. These initiatives include apprenticeship programs, vocational training programs, and partnerships with educational institutions to develop training programs. Graybar, a distributor of electrical products and solutions, has developed a workforce development program called Graybar University to provide training and education for employees, customers, and partners in areas such as lighting, automation, and safety. Joint apprenticeship training program Collaboration among industry, education, and government is crucial for developing solutions The International Brotherhood of Electrical Workers (IBEW) and the National Electrical Contractors Association (NECA) have developed a joint apprenticeship training program that provides training and education for individuals looking to enter the electrical industry. The program provides on-the-job training and education in areas such as electrical theory, safety, and installation. Collaboration among industry, education, and government is crucial for developing solutions to the labor shortage in the electrical industry. This includes partnerships between industry and education institutions to provide training and education programs, as well as government initiatives to support workforce development in the skilled trades.

Orchestral formations on the stage can also be tested and arranged in advance – before a single note is heard in the real world. This approach saves money, resources and time. Siemens to use digital twins “With Sound of Science, we’re designing the future. Digital twins are not only transforming the everyday for many companies, but are also creating new opportunities for the cultural and creative industries,” said Prof. Dr. Stephan Frucht, Artistic Director of the Siemens Arts Program. Dr. Stephan Frucht adds, “In the future, we’ll be able to plan stage productions better and even simulate them acoustically in advance. We’re delighted to have the Salzburg Festival at our side as a long-standing partner, who recognizes the opportunities such innovations offer.” Sound of Science app for select partners Siemens will make the Sound of Science app available to selected partners from the cultural world free of charge as a demonstration application. There are currently no plans to market the application. Its simulation solutions, however, may be purchased. The Salzburg Festival’s Großes Festspielhaus is the first and only large event space to date in which Sound of Science is available. However, Siemens is planning to digitally simulate further spaces – including concert halls in Germany and England. At the Salzburg Festival, audiences will have an opportunity – unique for the time being – to use VR glasses to experience the application at the festival’s opening on July 20. Siemens and the Salzburg Festival “Siemens and the Salzburg Festival share a common passion for excellence and innovation. And we’re delighted to partake in this pioneering technological development and innovation as part of our long-standing close and trust-based partnership,” said Dr. Kristina Hammer, President of the Salzburg Festival. Dr. Kristina Hammer adds, “We’re excited to see what diverse applications will stem from Sound of Science in the future.” Siemens Simcenter’s simulation solutions The technologies used are part of the simulation solutions from Siemens Simcenter The technologies used are part of the simulation solutions from Siemens Simcenter, which has been part of the company’s core business for over 15 years. The technology is mostly used in industry – for example, for the acoustic optimization of vehicle interiors or for protection against street noise. For Sound of Science, Simcenter uses a combination of impulse response measurements and ray tracing for the 3D modeling of each event space. These methods can measure the echo and reverberation of a sound and simulate how sound waves propagate in a room. Depending on the material, reflections of sound waves behave differently. Those that bounce off a concrete wall react differently from those that hit a carpet or reach the ear directly. As a result, the simulation can reproduce the individual sound signature of each event space – in other words, its acoustic DNA. Siemens Festival Nights Siemens has been working closely with the Salzburg Festival for around 30 years. Since 1999, the company has also been the festival’s main sponsor. Since 2002, the Siemens Festival Nights have been held on Kapitelplatz square during the Salzburg Festival. Since its beginning, this open-air event has provided more than one million visitors with the opportunity to experience previous and current festival productions on an LED screen free of charge. In addition, some of the Salzburg Festival’s venues are equipped with Siemens technology from the areas of building automation, security and acoustics.
