Optimal Configuration of Hybrid Energy Storage System Capacity Based on Gravity Energy Storage Battery
A hybrid energy storage system consisting of gravity energy storage batteries and supercapacitors is pro-posed to address the issues of high cost,short lifespan,and environmental pollution in energy storage systems based on electrochemical energy storage battery technology.The research focuses on stabilizing wind power output while re-ducing wind and electricity abandonment rates.Taking the lowest investment cost of the energy storage system and the lowest wind farm curtailment rate as the dual goals,a hybrid energy storage system capacity optimization configuration model was established,and the Pareto Archive Multi-objective Particle Swarm Optimization was used to solve the model to determine the hybrid Energy storage system with the highest wind farm yield.Through the comparative analy-sis of three different hybrid energy storage system combinations,the feasibility of the proposed hybrid energy storage system and energy storage capacity optimization configuration scheme was further verified.The simulation results show that the hybrid energy storage system based on gravity energy storage has good economy and feasibility.
