Comprehensive Evaluation of Park-Level Integrated Energy System Based on DEA Game Cross Efficiency Model

For the park-level integrated energy system (PIES) of "source-network-load-storage", comprehensive evaluation and selection of system planning and design schemes are carried out to ensure high-efficiency operation in actual production and provide decision-making reference for the later development and management of the system. According to the structure and characteristics of PIES, the benefit evaluation index system and index model are constructed from the four dimensions of economy, environment, reliability and energy consumption. Considering the competitive relationship between different weight and the nature of multi-attribute comprehensive evaluation, based on the DEA game cross efficiency model, the indicator weight assignment and system planning scheme efficiency calculation are completed, and the planning scheme decision is completed by the efficiency value. The example comprehensively evaluates the five planning schemes of the PIES, obtains the order of their superiority and inferiority, determines the optimal planning scheme. The results show that the evaluation system and model are reasonable and effective. The evaluation results are Pareto optimal after several game iterations.
