Abstract: In this paper,to solve the low robustness caused by special meteorological data in the traditional optimization configuration process,a multi-objective optimization model for economy,stability and environmental protection of micro-grid system is established,and restriction associated with electric energy storage state of battery and super capacitor,maximum instantaneous power requirement and power balance is built. On this basis,the multi-objective optimization issue of microgrid is analyzed. Firstly,the multi-objective optimization issue is transformed into a single target solution by utilizing the linear weighted method. Secondly,the optimal configuration combination of wind/light/micro gas turbine/battery in the microgrid is obtained based on the high robust fast particle swarm optimization algorithm. Finally,some examples related to pre-and post-robustness improvement are established,and comparisons of the economic and environmental protection are conducted to validate the effectiveness of the proposed algorithm.
