Dynamic evaluation method for running state of integrated energy system

Abstract

A dynamic evaluation method for the running state of an integrated energy system comprises the steps that firstly, multi-stage data of the integrated energy system are collected, and an index system including the technical, economic and environment-friendly integrated energy system is constructed; secondly, analyzing the influence of the indexes on the running state of the integrated energy system, dividing the indexes into benefit type indexes and cost type indexes, and calculating to obtain a standard index matrix; thirdly, inviting an expert group to carry out importance sorting on the index system, comprehensively considering influence factors of experts, and applying a group G1 method to obtain an index weight; then, a TOPSIS method is used, an absolute ideal solution is set, and the close degree is solved; and finally, according to the operation state characteristics of the multi-stage comprehensive energy system, performing dynamic evaluation by using a double-excitation control line principle. According to the method, one-sided reflection of a single type of index on the running state of the integrated energy system is avoided, the development trend of the integrated energy system is considered, the evaluation result can be more comprehensive, and the method is of great significance in guiding running and planning of the integrated energy system.

Description

technical field [0001] The invention relates to the technical field of comprehensive energy, in particular to a dynamic evaluation method oriented to the operation state of a comprehensive energy system. Background technique [0002] With the continuous development of my country's industrial system and the continuous improvement of people's living standards, the demand for energy is also increasing. At the same time, the use of fossil energy has brought about an environmental crisis, and the contradiction between the pollution discharge caused by energy use and environmental protection is also deepening. With the promotion of environmental protection and energy utilization, the rapid development of integrated energy systems has become a hot topic in current research. Accurate evaluation of the operation state of the integrated energy system can timely and effectively feedback the weak links of the integrated energy system value, and can play a guiding role in the operation ...
