Abstract
The virtual pumped storage power station based on compressed air energy storage combines compressed air energy storage and pumped storage technology organically,complements each others advantages,and adopts efficient hydraulic equipment to com-press air.During the power regulation process of the power station operation,it controls the head of high-pressure pool to be stable,improves the efficiency of pump-turbine unit,and operates the power station efficiently and steadily.It designes a power station with a capacity of 1 MW,and puts forward the power regulation strategy for stable operation of power generation and electric conditions.It establishes the mathematical model of each module of the power station.According to the power regulation command,the values of ope-ration parameters are obtained when the power plant efficiency is maximum.By controlling the driving equipment to adjust the running speed of the hydraulic piston rod,the water head of the high-pressure pool can reach the optimal value.It simulates and analyzes the running process of the hydraulic piston and the fluctuation of the head of the high-pressure pool,which verifies the feasibility of the strategy.关键词
