Energy Management for Short Term Storage Systems in Wind Parks

The stochastic fluctuating offer of wind energy limits the supply capacity in electrical grids by means of technical and economical reasons. A concept of dynamic conditioning was developed, witch envisages support and management of the electrical grid respectively through compensation of active and reactive power with static converters and short-term storage. Therefore short time fluctuation of the energy sources and changes of the load can be absorbed directly on location. By the use of dynamic storage systems an intermediate storage of the wind energy is implemented. This low order energy can thereby be converted into high order callable energy. The therefore necessary storage capacity depends on the storage management method.
