In addition to grid expansion, the successful implementation of the energy transition in Germany is only possible with the storage of renewable energies in order to compensate for the natural fluctuation of RE. The various storage technologies on the market have a special role to play here: in addition to storing energy, the systems must be able to adapt dynamically to demand and ensure grid stability at the same time. This applies regardless of the size and design of the system. In terms of grid integration, these storage systems therefore take over the tasks and system services of conventional generation plants (wind, photovoltaics). This means that the same requirements apply to storage systems as to other decentralized generation systems, regardless of the operating mode: storage systems with (bidirectional) converters must also be electrically measured with regard to the grid connection.

This is done in the unit certification, which forms the basis for the system certification. M.O.E. covers all certification processes for this area via component certification (e.g. parking controllers) and model validation. Currently, system certification is carried out in accordance with VDE-AR-N 4110 “Technical rules for the connection and operation of customer systems on the medium-voltage grid (TAR Medium Voltage)” in conjunction with FGW TR 8. The certification obligation applies to all storage systems from a size of 135 kW and a self-consumption of 500 kW at the latest when connected to the medium-voltage connection, i.e. from 1 kV to 60 kV. Further details on these topics can be found on the certification pages. If you have any questions about certification or other storage services, please do not hesitate to contact us.
