在微电网中综合考虑经济和环境两个目标，以各微源的运行上下限为约束条件，采用粒子群算法在matlab环境下进行了仿真，最后给出了微网各微源的最优机组组合方式和最佳电能交易计划。(The first establish micro multi-objective energy optimal operation model, taking into account both environmental and economic factors in the model, the operation of the various micro-source conditions and micro-grid electric power balance constraints, the establishment of a multi-objective function. To a typical micro-grid running instance As an example, the use of particle swarm optimization strategy and simulation in MATLABLAB environment,micro-source output for　microgrid actual environmental economic dispatch .)
