Energy storage capacity configuration for large-scale wind power accessed to saturated system

The wind power may cause ever-growing and serious stability hazard for power system, and energy storage plays a very important role in improving the static and dynamic stability of power system. The role of energy storage is introduced in solving wind power integration problem and an electromechanical static model of flow-based energy storage is set up. The capacity requirement of energy storage for system stability with wind integration is calculated by simulation, and relevant configuration method is proposed. In view of a typical power system with wind power integration, the required energy storage capacity is calculated with the proposed method for achieving the static and dynamic stability. Finally, simulation has proved the effectiveness of the proposed configuration strategy.
