Wind Energy Storages - Possibilities

The volatility of wind power can cause large problems for power systems operation. To remedy the disadvantages of wind power generation different storage technologies can be applied. In this paper technical and economical analysis of possible wind energy storages has been made. According to technical parameters the applicable technologies have been selected. Afterwards, for selected storages economical analyses which take into account different scenarios of investment and electricity prices have been made. Obtained results suggested compressed air energy storages, batteries and pump hydro storages as very good solutions for wind energy storage. Due to lack of suitable places in Germany a pump hydro storage solution is less feasible.
