STUDY ON OPTIMAL SCHEDULING METHOD FOR GRID CONNECTION OF HYDRO-PV COMPLEMENTARY SYSTEM
摘要
Abstract
Against the backdrop of increasing the proportion of renewable energy connected to the grid,this paper proposes a hydro-PV complementary system grid connection optimization scheduling method.Focusing on maximizing the peak regulation capacity of the hydro-PV complementary system,and minimizing the deviation between output power of hydro-PV complementary system and load demand,the method is applied to a hydro-PV complementary project in Xinjiang.The NSGA-Ⅱ algorithm is used to analyze the output power of the hydro-PV complementary system under three weather scenarios:sunny,cloudy,and rainy days.The results show that:1)Under three weather scenarios,the maximum output power of the hydro-PV complementary system can reach 1124 MW,with a 15.9%increase in peak regulation capacity compared to using only hydropower.2)Compared with separate hydropower and PV power generation,the hydro-PV complementary system exhibits stronger peak regulation ability and more precise matching of output power curve to load demand curve,demonstrating the effectiveness of the NSGA-Ⅱ algorithm in optimization scheduling.3)Hydro-PV complementary system can effectively absorb PV power generation and achieve stable power generation,offering new ideas for the effective utilization of renewable energy.关键词
