The metering days in Fulda are from 9.10.-10.10.19 focuses on current trends and the energy policy orientation of the energy sector.

Exciting keynotes, interesting solutions, and intensive discussions provided plenty of input for the 700 participants.

‍EEBUS initiative

EEBUS is a communication protocol that connects flexible consumers and the grid via an EMS

Input was also brought to the metering days by the EEBUS initiative. The energy grid is becoming increasingly flexible and decentralized, and at the same time, electric mobility is a new major area.

This requires the seamless exchange between generators, the power grid, and the individual devices in the buildings as well as the car. EEBUS is a communication protocol that connects flexible consumers and the grid via an EMS.

‍Grid Interaction

Theben, KEO, and gridX jointly presented the use case "Grid Interaction" within the EEBUS initiative. A demo showcase with Theben Conexa 3.0 SMGW and the corresponding gridX energy management system "gridBox" was introduced.

The performance limitation of the grid operator is transmitted to the energy management of gridX within the use case. This intelligently and dynamically reduces the output of the connected electric car in the household. At the metering days, it was possible to show how EEBUS can be implemented in practice.

‍"gridBox" energy manager

The building, or a group of interconnected residential units, thus appears in the network as a unit

Heat pumps, charging stations for electric cars, or photovoltaic systems with battery storage are collected via EEBUS communication and are made available as flexible consumers in the distribution network.

The building, or a group of interconnected residential units, thus appears in the network as a unit with a certain degree of flexibility. The "gridBox" energy manager from gridX ensures that the limit values specified by the network operator are adhered to at the hose connection point.

‍power limitation

A communication stack is provided via EEBUS. The network operators must limit this to avoid fluctuations and blackouts. The energy drawn from the grid is thereby reduced. gridX controls the power of the decentralized consumers and thus ensures the power limitation at the grid connection point.

With this application, the EEBUS partners demonstrate that they are already able to implement smart grid applications securely and flexibly.
