Optimization of Battery Application for Wind Energy Storage

Abstract

The largest disadvantage of wind energy is the lack of exact predictability and its fluctuations, which are causing problems in the power system operation. The consequence is that even though other energy sources can be saved by using wind energy, the short-term power fluctuation has to be secured by a conventional plant. A possible solution can be the storage of wind energy. In this paper battery systems are analyzed as a backup for a 400 MW offshore wind farm with help of special developed calculation models. The goal is to reach small difference between forecasted and actual wind power and to increase the reliabilty of delivered wind energy using battery systems. For the determinations the properties of the battery system are considered and integrated into the calculation model. The overall target is to reduce the reserve energy requirement of the offshore wind farms.
