摘　　要：针对独立型微电网容量配置存在经济成本和供电可靠性难以实现同时最优的问题,提出一种实现经济成本和供电可靠性最优的独立型微电网容量多目标优化配置方法。根据独立型风光储微电网系统中各分布式电源的机理构建风机、光伏、磷酸铁锂电池的数学模型,以等年值投资成本为评估指标构建独立微电网经济成本模型,功率偏差为评估指标构建出基于层次分析法的独立微电网可靠性模型,使用非支配排序的多目标粒子群算法求解系统最优容量配置。算例结果表明,该方法对独立型微电网容量配置在同时实现供电可靠性和经济性上更有优越性。In order to solve the problem that the economic cost and power supply reliability of independent microgrid capacity allocation are difficult to achieve simultaneously,a multi-objective optimal allocation method of independent microgrid capacity is proposed to achieve the optimal economic cost and power supply reliability.A mathematical model of a wind turbine,a photovoltaic and a lithium iron phosphate battery is constructed according to the mechanism of each distributed power supply in an independent wind-photovoltaic-storage microgrid system;an independent microgrid economic cost model is constructed by taking the equal annual investment cost as an evaluation index,and an independent microgrid reliability model based on an analytic hierarchy process is constructed by taking the power deviation as an evaluation index;Multi-objective particle swarm optimization with non-dominated sorting is used to solve the optimal capacity configuration of the system.The example results show that the proposed method is more advantageous in achieving both power supply reliability and economy for the capacity allocation of independent microgrid.
