In order to reduce wind and solar abandonment caused by the fluctuation of wind and solar output, using the regulation and storage characteristics of different types of hydropower such as cascade hydropower and pumped storage, a joint operation strategy of multiple types of hydropower to coordinate and participate in wind and solar absorption is proposed. Types of hydropower output, reservoir storage capacity and tie line transmission power, etc., with the investment and construction cost of wind and solar power stations, the minimum system operation and maintenance costs, and the minimum power purchase cost, and the largest proportion of wind and solar power generation to the load demand. The power station capacity optimization configuration model is solved by the particle swarm optimization algorithm (ELM-PSO) based on the extreme learning machine. Taking a certain area in Qinghai as an example, through simulation analysis, it is concluded that the system economy and the proportion of wind and solar power generation in the load demand are comprehensively considered The optimal capacity allocation scheme verifies the feasibility and effectiveness of the proposed strategy and the built model.
