Multi-purpose energy storage management and ICT requirements

Inhalt:
Fluctuating renewable energy sources are generating particular challenges for the energy sector. In part, the utilization limits in the distribution networks have already been reached now. Until 2020 in the northern regions of Germany there will stand 50-60 GW increase of regenerative energy generation against 12 GW increases of transport capacity [1]. Therefore, the search for new technical options to master the energy transition phase is essential. As an alternative to grid expansion, it is necessary to make a variety of electric storage devices usable. In particular the implementation of storage systems with intelligent load management has to be investigated, including new operational methods as e.g. multi-purpose operation. This paper describes energy storage use-case considerations of a decentralized storage system and their incentives for future operations. Furthermore, it will describe different contemplations on how to share the storage capacity between, on one hand, local demand side management with focus on high energy and cost efficiency and, on the other hand, the needs of a higher level integrative storage management. Therefore, the paper gives an overview about interconnection between the decentralized energy storage management and the higher layer management through an ICT network, e.g. public internet.
