Research On The Comprehensive Evaluation And Optimization Strategy Of The Comprehensive Energy System In The Park

The integrated energy system is a part of the energy network,and the development and establishment of the integrated energy system is of vital significance to the realization of the integrated energy network.Improve the comprehensive energy survey and evaluation system,establish the economic and technological development evaluation system,improve the evaluation method,refine the evaluation index system,and have a positive guiding significance for the feasibility study and analysis of the comprehensive energy construction project and the actual implementation of the project construction..This paper deeply analyzes various factors that have a great impact on the development of the integrated energy system,and analyzes the impact of five factors on the development of the integrated energy system,including industrial development,investment benefits,social culture,ecological environment,and government subsidies through the fishbone diagram separation method.The larger factors are selected,and the evaluation index set is selected to form a comprehensive evaluation index system of the comprehensive energy system.In order to facilitate the calculation,the qualitative indicators are quantified through the idea of fuzzy concepts,and the quantitative indicators are calculated by using the operation simulation method based on multi-scenario technology.Based on the study of matter-element extension,the matter-element extension method is improved,and an extension model more suitable for the index system of this paper is obtained.According to the combination weighting method,a new AHP-entropy weight is obtained.A comprehensive evaluation model of law-matterelement extension method.Taking a park in East China as an example,through the study of the evaluation results,the advantages and disadvantages of the integrated energy system are analyzed.Taking clean energy penetration as a variable of sensitivity analysis,it is found that the existing integrated energy system still has limitations,and the integrated energy system is improved based on the problems found.By adding hydrogen storage and energy generation modules to the original comprehensive energy base,a clean energy system is formed.The basic goal is to minimize the annual average cost,and the annual maximum load power shortage rate is the basic constraint to achieve optimal capacity allocation for the clean power system.Through the comparative analysis of the above-mentioned various methods,the optimal configuration scheme is obtained.And evaluate the improved integrated energy system...
