Economic Dispatch in Multi-Microgrids with Consider Electric Vehicles Under Uncertainty

In this paper, for interconnected multi-microgrids (MMGs) and in the presence of electric vehicles (EVs) economic dispatch at MMGs under uncertainty is introduced. Probabilistic modeling considered for load demand andenergy resource. In this paper, to increase network reliability, microgrids (MGs) operate in interconnected mode andeach MGs can sharing power with external network and with other MGs. Balance between the load demand dna totalgenerated powers in each MGs are considered. Each MGs can purchase and sold power of course with considering power balance constraint. Consider the particle swarm optimization (PSO) algorithm to minimize the cost function. The results confirm that the presence of electric vehicles can helping to self-sufficiency each MG and decrease the operating cost of the smart distribution networks.
