针对包含风力发电机、光伏电池、柴油发电机、储能及海水淡化的独立微电网系统，提出了一种兼顾经济性、可靠性和环保性的容量优化配置模型。根据系统的调度策略，在满足决策变量变化范围、各微源及海水淡化机组运行要求的条件下，以最小化系统综合成本和最大化供电可靠性为目标，对风力发电机、光伏电池、柴油发电机和蓄电池的容量进行优化。系统综合成本包括初始投资成本、运行维护成本、燃料成本、治污成本及可再生能源浪费惩罚成本。可靠性综合考虑了缺电量及停电时间的影响。该模型可在满足负荷用电需求的前提下，尽可能地减少冗余投资，并充分利用清洁能源发电，减少环境污染。算例结果验证了模型的合理性。

This paper proposed a capacity optimization of stand-alone microgrid consisting of wind power generator,PV,diesel generator,energy storage system and seawater desalination system,taking economy,re-liability and environment protection into account.Based on the dispatching strategy and constraints of this hybrid system which includes the range of decision variables,the operation characteristics of micro power sources and desalination units, the capacity of different power sources are optimized with the minimum composite cost and maximum reliability as optimization objective.Composite cost includes initial investment cost,operation and maintenance cost,fuel cost,pollution treatment cost and punishment cost of wasted renewable energy.Reliability takes both the amount and time of power supply interruption into consideration. This model can decrease the cost as much as possible with the load's demand satisfied.Meanwhile,renewable energy can be taken full advantage of and environment pollution can be effectively relieved.The reasonableness of the proposed model is verified by a case study.
