Battery systems in distribution grids
The aim of this study is to identify possible grid and/or system-related effects of a further progressing, possibly large-scale, installation of decentralised battery systems and to assess whether and which measures should be taken to counteract any problematic effects. The main areas of impact to be considered are as follows:
- Allocation, levy and fee systems whose revenue and distribution effects are influenced by the penetration of decentralised storage systems and which also provide significant incentives for the use of electricity storage,
- the load and operation of distribution and transmission systems and related aspects of grid costs and security of supply; and
- the operation of the conventional power generation system.
