Optimal capacity allocation of wind-solar-storage system with hy-brid energy storage

Due to the continuous development of renewable energy sources, the demand for various energy storage technologies in power grids is increasing. By proposing a hybrid energy storage system with gravity storage using abandoned mines to solve the problem of new energy consumption. The capacity optimization mod-el of the microgrid is established with the objective of minimizing the annual average system cost, and the characteristics of each power generation unit of the microgrid containing wind turbine, photovoltaic mod-ule, battery and gravity energy storage device are analyzed, and the model is optimally solved by using an improved particle swarm optimization algorithm. The results of the algorithm show that the model im-proves the economy of the system, and the reliability indexes such as the system load outage rate are sig-nificantly improved.
