针对目前微电网容量配置存在的问题，提出一种新的微网容量配置多目标优化方法，对微电网规划中的分布式电源容量和储能系统容量进行联合求解，同时进行优化配置。以1000 kV变电站站用电系统为例，运用微电网规划设计软件DGPO分别对以光储微网系统、风储微网系统、风光储微网系统等3种系统作为变电站站用电系统的补充电源方案进行设计，推荐采用一种并网/离网运行的光储微网系统作为变电站站用电系统的补充电源。

According to the existing problems in the capacity configuration of current micro￣grid, a new multi￣objective optimization method was proposed for the capacity configuration of micro￣grid, by which the combined solution and configuration optimization of distributed generation capacity and energy storage capacity in micro￣grid planning could be carried out at the same time. Taking a auxiliary power system in 1 000 kV substation as example, this paper applied micro￣grid planning software DGPO to design three different supplementary power schemes for UHV auxiliary power system, including photovoltaic storage micro￣grid system, wind storage micro￣grid system and wind￣photovoltaic storage micro￣grid system. Finally, a grid￣connected/off￣grid photovoltaic storage micro￣grid system was recommended as supplementary power for substation.
