Abstract：Aiming at the problem of supply reliability and economy during microgrid power supply configuration process，researches were done to size distributed resources. Setting cost divided in each year as objective function，the numbers of wind turbines and batteries as optimization variables，supply reliability as constraints，using traversal algorithm to calculate optimal solution，configuration of microgrid was calculated. On the premise of the economy，hybrid energy storage system was adopted，taking advantage of high power density of super capacitor and high energy density of battery. On the premise of the reliability，mean filtering strategy was adopted to deploy energy between super capacitor and battery to cease energy accumulation in the super capacitor. Based on Matlab platform the method proposed was implemented and applied to an example. The results indicate that the method proposed is effective so that the method proposed can achieve economical configuration on the premise of stability. New ideas for distributed resources sizing method are suggested.
