The metering days in Fulda from 9.10.-10.10.19 focus 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.
Input was also brought to the metering days by the EEBUS initiative. The energy grid is becoming increasingly flexible and decentralised, and at the same time electro mobility is a new major consumer. This requires the seamless exchange between generators, the power grid and theindividual devices in the buildings as well as the car. EEBUS is a communication protocol thatconnects flexible consumers to each other and to the grid via an EMS.
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.
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 house connection point.
A communication stack is provided via EEBUS. The network operators must limit this in order to avoid fluctuations and blackouts. The energy drawn from the grid is thereby reduced. gridX controls the power of the decentralised 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.
Climate change is the biggest challenge of our times but today's power grid is not built for the uncertainty and decentral nature of renewable energies. gridX builds the digital infrastructure to enable the energy transition. Therefore, gridX develops XENON the platform to connect all distributed energy resources. gridX customers can develop their own energy applications on top of XENON or opt for ready-made solutions.
