Predictive control strategy of energy storage system in distribution system with wind power

A predictive control strategy of energy storage system in distribution with wind power is proposed. This strategy can effectively reduce the power output fluctuation of wind-storage combined generation system in distribution system. Firstly, the model of combined system is established according to the mechanism of the energy storage system in the combined generation system, and the charging/discharging model of the energy storage system is established according to the operating constraints of the energy storage system. Then, the short-term output power of the wind farm is predicted by the method of model prediction, and the control strategy of the energy storage system to restrain the wind farm fluctuation is determined by combining the real-time state of the energy storage system. Finally, a simulation environment was built in Matlab, and the advantages and effectiveness of the predictive control strategy are verified by comparing and analyzing the simulation results of the energy storage system under time-sharing/predictive control strategy.
