An Integrated Energy System Evaluation Method Based on FAHP-EWM-TOPSIS

Abstract

The integrated energy system (IES) of the park integrates multiple types of energy such as electricity, heat, cooling, and gas, and objective and accurate evaluation of them is the basis for subsequent dispatch management and energy structure adjustment As the current IES evaluation method lacks indicators in terms of multi-energy complementation and system energy consumption, a new park IES evaluation method is proposed for this. First, a comprehensive IES evaluation index system is established. And through fuzzy comprehensive evaluation method (FAHP)-entropy weight method (EWM) combination of subjective and objective weighting method to weight indicators, combined with technique for order performance by similarity to ideal solution (TOPSIS) for program evaluation. Finally, a case study is carried out based on IES to verify the rationality of the proposed evaluation index system and the effectiveness of the evaluation method.
