Evaluation Index System and Evaluation Method of Microgrid Friendly Interaction Ability

The friendly interaction ability of microgrid can reduce the regulation burden of external distribution network and increase the reliable power supply to its internal loads, which is critical to microgrid operation performance. The evaluation index system of microgrid friendly interaction ability is defined from three dimensions: balance ability, flexibility and recovery ability, which can comprehensively describe the characteristics of microgrid operation. The entropy weight (EM) method and the weighted rank sum ration (WRSR) are used to evaluate the proposed index system, which can effectively eliminate the interference of abnormal values to the evaluation results. The case study is conducted to verify the effectiveness of the proposed evaluation index system and the EM-WRSR based evaluation method.
