Energy Management Strategies for Optimization of Energy Storage in Wind Power Hybrid System

Wind energy has become the most promising alternate energy source and has reached high levels of penetration in many networks worldwide. Energy storage can provide additional beneficial features to wind and aid in its further growth. However, this comes at a cost and therefore the goal is to minimize the size of the storage device while at the same time taking advantage of its promising features. This paper proposes an energy management system based upon fuzzy logic in order to optimize the use of the storage. This strategy was illustrated for a system interfaced with the electric grid using a voltage source converter. System studies were performed to demonstrate the advantages of this strategy and future developments are considered
