Research on the control strategy of large-scale wind power energy storage system

Different from conventional generators, wind power is an intermittent energy source, power system dispatch and control is confronted with new challenges. This paper establish the mathematical model of wind power and energy storage system for simulation and analysis, and study the wind power prediction using statistical methods and physical methods, and study the key technologies of automatic generation control and automatic voltage control which were in the large-scale wind power and energy storage system. The results show that the wind power prediction is reasonable for grid, and the power quality and stability of wind farm connected to power grid can be well improved by battery energy storage.
