doi:10.11930/j.issn.1004-9649.202006250

Abstract

Abstract: According to the multi-energy coupling characteristics of the park-level integrated energy system (IES), the influencing factors of the IES construction are analyzed. Considering the positive impact of electric power substitution, an index system is built with such indexes as social benefits, energy utilization efficiency, reliability, economy and environmental protection, and a quantification model and calculation method for the indexes are proposed as well. A comprehensive evaluation method is proposed using combination weighting method to optimize the matter element extension model, in which the combination weighting method is used to integrate the subjective and objective weights according to the theory of minimum weight deviation vector, and the obtained expected combination weights are applied to the matter-element extension model to give the evaluation grades of the construction schemes. The case study has verified the scientificity and rationality of the proposed evaluation method, and demonstrated the positive effects of electric power substitution equipment on the construction of the park-level IES.

Key words: park-level integrated energy system, electric power substitution, index system, combination weighting, matter element extension analysis
