Study on optimal operation of cascade hydropower stations under complex constraints

摘要

With daily regulating storage of cascade hydropower station group as the object of research, Studied under time-sharing electricity price, traffic delay, meet the daily load power generation and power supply, and other complex constraints, and combined with the characteristic of power plant, establish the mathematical model of the daily regulation of cascade hydropower station generating economic benefits maximum ,the successive approximation algorithm combined with the dynamic programming algorithm and the successive approximation algorithm combined with POA are respectively Programming calculated and compared to verify. Through the actual simulation of the cascade hydropower station group of Sichuan Mingxing electric power company, the results show that the obtained strategy can meet the needs of the dispatching of cascade hydropower stations, and can achieve better economic benefits. It is a practical and feasible scheduling method and strategy
