In the regions which are located far from the distribution networks, using standalone microgrid to supply the power demand with minimum cost and best reliability is essential. Optimal sizing of Distributed Energy Resources (DERs) in a typical microgrid is a complex multi-objective problem. In this paper a multi-objective modelling for designing a standalone microgrid with the best reliability and minimum cost for supplying the load demand is investigated and modelled. The proposed method is based on consumers demand and their consumption patterns.Specification index of proposed method is preventing from oversizing of microgrid components.
