Comprehensive Evaluation Strategy of Optimal Operation Mode of Integrated Energy System Based on Analytic Hierarchy Process

Abstract

The modeling, operation and scheduling of integrated energy system (IES) for “carbon peak and carbon neutral” is the focus of scholars at home and abroad. A comprehensive evaluation strategy of optimal operation mode of IES is proposed based on analytic hierarchy process (AHP). Firstly, the IES evaluation index is constructed, including energy saving rate, energy loss, new energy proportion, new energy consumption rate, and operation and maintenance cost. Then, the optimal operation mode model of IES is established, including the economic optimization operation mode, environmental protection optimization operation mode and energy saving optimization operation mode model. Secondly, the optimal operation mode of IES is evaluated based on AHP comprehensive evaluation. The process includes establishing the hierarchical structure model of IES, constructing the comprehensive evaluation judgment matrix of IES, single ranking and consistency test of IES level, general ranking and consistency test of IES level. Finally, an example is given to verify the effectiveness, practicability and rationality of the proposed comprehensive evaluation strategy. The results show that the proposed comprehensive evaluation strategy can effectively evaluate the optimal operation mode of the IES, and can provide theoretical guidance for the optimal operation mode.
