Comprehensive evaluation method of microgrid planning scheme considering synergistic benefits of electric vehicles and distributed renewable energy sources

In the environment of smart microgrid, electric vehicle charging infrastructures and distributed renewable energy generation systems share some significant synergistic benefits in the working mechanism. The research on comprehensive evaluation method of microgrid planning schemes considering synergistic benefits of the two mentioned above has important theoretical meaning and project application value. Based on the typical microgrid integration model in different application backgrounds, a complete evaluation index system is established. Then, a comprehensive method based on multi-attribute decision to evaluate the integration scheme is also proposed. Combined with actual case of mutual competitive microgrid planning schemes, concrete steps of the proposed method are presented in detail. Interaction among factors belonging to different hierarchies is analyzed. Fuzzy analytical hierarchy process and the Blin method is introduced to perform comprehensive quantified analysis on the indices and the weights of these indices are determined. Reasonable analysis results are attained, thus the effectiveness and practicability of the proposed method are verified, which is conductive to the decision of microgrid planning schemes.
