The invention relates to a capacity optimization configuration method for a micro-grid system multi-benefit subject, the micro-grid system multi-benefit subject comprises a virtual power plant and an independent energy storage power station, and the method comprises the following steps: firstly, constructing a target function of the annual cost of the virtual power plant by taking the lowest annual cost and wind and light curtailment as little as possible as consideration factors; constructing a target function of the independent energy storage power station by taking the lowest annual cost and the service life of an energy storage battery as long as possible as consideration factors; then, obtaining constraint conditions of stable operation of each benefit subject; and finally, constructing a multi-benefit win-win capacity configuration model of the micro-grid system based on Pareto optimization, searching a Pareto frontier by using a multi-target particle swarm algorithm, and selecting a point closest to th
