Wind power generation, thermal power generation and compressed air energy storage integrated power generation system

Abstract

The invention discloses a wind power generation, thermal power generation and compressed air energy storage integrated power generation system. The integrated system is mainly composed of a wind power plant, a thermal power plant and a compressed air energy storage power station. The wind power plant and the thermal power plant are connected through a compressed air system to form a wind power, thermal power and energy storage integrated power generation system. The compressed air energy storage system adjusts power output according to a grid load requirement and the output condition of the wind power plant and the thermal power plant to achieve linkage of the wind power plant and the thermal power plant and improve grid load response capability. Under the condition that grid safety is ensured, more clean energies can be connected into a grid. The compressed air energy storage system utilizes high temperature slag generated by the thermal power plant to generate power and replaces the traditional way that a traditional compressed air energy storage system utilizes natural gas to generate power. Therefore, the system has high environment benefit. Meanwhile, the system is high in peak load adjustment capability. By means of the system, the grid can receive wind power in a large scale, and the peak adjustment capability can be improved.
