Research on the Benefit Evaluation Method of Green Energy Microgrid Construction and Equipment Access

Firstly, this paper summarizes the current microgrid evaluation indicators and constructs an evaluation indicator system from four aspects including reliability, economy, technology and environmental protection, from which the comprehensive evaluation of the microgrid is carried out. The DEMATEL (Decision Making Trial and Evaluation Laboratory method) and AHP (Analytic Hierarchy Process) are combined to calculate the subjective weights of each indicator, and the CRITIC (Criteria Importance Though Intercrieria Correlation) and EWM (the Entropy Weight Method) are combined to calculate the objective weights of each indicator, and then the VIKOR (VIseKriterijumska Optimizacija I Kompromisno Resenje) is used to determine the optimal program among the microgrid construction alternatives by comparing the group benefits and individual regrets of each program after introducing the personal preferences of decision makers. Finally, the feasibility of the method is verified in the actual arithmetic example, and the corresponding suggestions are provided for the planning and construction of green energy microgrid.
