Description
Changes in the electric energy systems due to higher shares of unpredictable renewable energies will lead to a higher energy balancing demand. This can be achieved by real energy storage devices or by different balancing options, e.g. demand side management. To ensure grid stability as well as maximizing the energy efficiency of such networks, storage is a key issue.
The overall objective of this annex is to develop a method or approach to calculate the regional energy balancing demand. The results are used to derive the respective regional storage demand rasterizing the area and considering competitive technical solutions. Therefore four work packages were implemented: WP1: Technical and economic framework conditions for energy storage systems; WP2 Calculation method to determine spatial demand for electric energy storage; WP3 Applications of electric energy storage systems (WP3); and WP4 Requirements for test procedures.
