Abstract

The invention discloses a comprehensive energy system evaluation method and system based on optimal combination weighting. The method belongs to the technical field of comprehensive energy system evaluation and comprises the steps that an evaluation index system of a comprehensive energy system with p layers is established according to all evaluation indexes of the comprehensive energy system, thefirst layer is a quantitative evaluation result of the comprehensive energy system, and the p layer is a (p-1)-level evaluation index; acquiring numerical values corresponding to the evaluation indexes under different configuration schemes, and constructing an index evaluation standardized decision matrix; calculating subjective weight and objective weight of each evaluation index by adopting a subjective and objective combination weighting method; according to elements, subjective weights and objective weights in the standardized decision matrix, comprehensive energy system evaluation results under different configuration schemes are obtained, and the configuration scheme corresponding to the maximum evaluation result serves as the optimal comprehensive energy system configuration scheme. The subjective and objective combination weighting method is adopted, the evaluation result is more scientific, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of comprehensive energy system evaluation, in particular to a comprehensive energy system evaluation method based on optimal combination weighting. Background technique [0002] With the gradual strengthening of people's awareness of energy conservation and environmental protection, the integrated energy system has gradually become the focus of the energy field. The joint supply of multiple energy sources enables cascaded energy utilization and mutual aid, and also increases the penetration rate of renewable energy, which makes it more economical and reliable than the traditional single energy supply distribution network. and environmental protection have changed. Different configuration methods of integrated energy facilities will also have different impacts. Therefore, comprehensive satisfaction evaluation of integrated energy systems with different configuration methods has important theoretical and prac...
