摘　　要：分布式电力系统中微电网功率最优化问题,是指在满足各个微网运行约束条件下优化各微网的出力,使整个微电网电压损耗最小、功率损耗最小和经济运行成本最优为目标函数。针对微电网孤岛运行时的优化调度问题,在微网模型的基础上建立了多目标优化模型,利用遗传算法,在三个目标之间采用线性加权法进行处理,将多目标优化转化为单目标进行求解,并通过算例仿真验证该方法的有效性。The aim of power load optimization for a distributed power system is to meet the operational constraints to optimize the power output of the microgrids and with the objective function of the whole microgrids voltage loss, line power loss and economical optimal. To carry out optimal scheduling for microgrid in stand-alone mode, a multi-objective mode was built based on the microgrid mode, then an improved genetic algorithm was put forward to solve the problem. Finally, the analysis of examples proved the proposed algorithm.
