Abstract

The invention provides an evaluation method for evaluating the energy efficiency of an integrated energy system. The method comprises the steps of in each of various integrated energy systems, collecting the parameters of an energy efficiency criterion layer, wherein the equipment of the energy efficiency criterion layer is composed of a distributed power supply, a power distribution network, a thermal network, an energy storage system and a load device, and each device includes at least one indicator; determining the evaluated value Ei of each energy efficiency evaluation index of the energy efficiency criterion layer, determining an index weight coefficient Wi corresponding to each evaluated value Ei, and determining the energy efficiency quantized value E=sigma (Wi*Ei) of an energy efficiency target layer of each integrated energy system, wherein i is a positive integer; comparing the energy efficiency quantized values E of any two integrated energy systems, and the evaluated values Ei of identical energy efficiency evaluation indexes; in an integrated energy system relatively low in energy efficiency quantized value E, screening out an index relatively low in the evaluated value Ei of an energy efficiency evaluation index, and optimizing the equipment having the above energy efficiency evaluation index.

Description

technical field [0001] The invention relates to the technical field of energy evaluation, in particular to an evaluation method for energy efficiency of a comprehensive energy system. Background technique [0002] The physical carrier of the Regional Energy Internet is the integrated energy system, and the power system is the core of the integrated energy system. On the one hand, although the current research on the energy efficiency evaluation of distribution networks is relatively extensive and the methods are mature, the integrated energy system under the environment of the Energy Internet places more emphasis on multi-energy coordination, heat and power complementarity, and source-grid-load interaction. The evaluation method only focuses on the distribution network, and it is difficult to conduct a more comprehensive energy efficiency evaluation of the integrated energy system; on the other hand, the current energy efficiency evaluation of the integrated energy system is...
