The future distribution network will be made of interconnected distribution systems, so called microgrids. Microgrids (MGs) provide an effective means of utilizing energy from small-scale renewable resources. The probabilistic power generation behavior renewable generations and load forecasting errors are the most important uncertainties in MG operation. The proposed methodology of this paper applies these uncertainties into the operation problem in order to find the practical solutions. So, in this research the economic operation of Multi-MGs (MMGs) is formulated as a cost-based objective function which is minimized using particle swarm optimization (PSO) algorithm. As a result, the problem outputs must be defined by Probability Distribution Functions (PDFs) in order to achieve comprehensive analysis of the literature. Another contribution of the paper, which rises the accuracy of the analysis in operation discussion, is applying suitable fitting criteria to select the best PDF for each obtained result based on Akaike's information criterion (AIC).
