Reliability and Economic Indices Assessment in Interconnected Microgrids

In this paper, the evaluation of reliability and economic indices of interconnected microgrids (ICMGs) in emergency conditions is done. In this way, exchanged power between microgrids (MGs) in both islanded and grid-connected modes is investigated. A power exchange algorithm based on economic and reliability features is proposed. In this algorithm, exchanged power between MGs based on customer interruption cost (CIC) and electricity prices (EPs) is represented. To evaluate the indices a new method is used, which has high accuracy. The efficiency of the proposed methods is examined for bus-2 of the Roy Billinton distribution System (RBDS) system and different scenarios tackling EP and CIC into the problem formulation. The evaluation results of the new method are compared with the results of the Monte Carlo method.
