摘　　要：风能和太阳能发电具有天然的互补性,因风能的波动性较大,太阳能又受时间和天气的影响,因此在进行风光储供电系统的设计中,优化配置占有很重要的地位.本文采用遗传算法(Genetic Algorithm,GA)进行风光储供电系统的多目标优化,优化目标是系统总成本(Total system cost,TSC)和全年负载缺电率(Loss of power supply probability,LPSP),文中采用两种风力发电机,一种光伏板,一种蓄电池对当地总负载进行配比,加入风力发电机输出功率、光伏板蓄电池数目等约束条件后,通过比较得出最优配比结论,旨在提高风光储离网系统的优化配置和经济性.Wind energy and solar power are naturally complementary.Due to the volatility of wind energy and the influence of time and weather on solar energy,the optimal configuration plays an important role in the design of wind solar storage power supply system.In this paper,the genetic algorithm(GA)is used for multi-objective optimization of wind solar storage power supply system.The optimization objects are total system cost(TSC)and annual loss of power supply probability.In this paper,two kinds of wind turbines,one photovoltaic panel and one battery,are used to match the local total load.After the constraints such as the output power of wind turbine and the number of photovoltaic batteries are added,the conclusion of the optimal ratio is obtained through comparison,which aims to improve the optimal configuration and economy of the wind solar storage off grid system.
