摘要：

In view of the characteristics of various types of energy utilization and wide range of input and output indices in the comprehensive energy system, a comprehensive efficiency evaluation model based on cross-super-efficiency CCR model is established by introducing the mature comprehensive evaluation theory in the operations research. The evaluation model is based on relative efficiency. Firstly, each index value is calculated according to the economic dispatch results of each integrated energy system. Secondly, the index value is substituted into the evaluation model to calculate the cross-super-efficiency of integrated energy system and then the comprehensive efficiency can be compared. Through an example of a small-scale park, the differences and their causes of the comprehensive efficiency of the park in summer and winter are analyzed, and the correctness and rationality of the comprehensive efficiency evaluation model are verified. The influence of installed capacity of wind turbine and heat pump on the comprehensive efficiency of integrated energy system is further analyzed and the optimal capacity allocation is determined. Compared with the evaluation results of the super-efficiency CCR model, the cross-super-efficiency CCR model is more reasonable and effective. © 2020 Automation of Electric Power Systems Press.
