Hybrid Energy Storage for Wind Electric Power Systems

As the renewable energy (wind energy, solar energy) being utilized more and more, there is strong demand for improvement on the policies of energy storage management. Several papers have shown that hybrid storage system is more efficient and economic than single storage system. In this paper, a policy based on the accurate prediction of wind speed in the near future is introduced and compared with state-of-charge (SOC) management approach and single storage system. The current simulation results demonstrate that the new policy proposed has a minor improvement on the set-up cost and the system performance over the state-of-charge policy.
