Distributed Energy System Scheme Optimization And Evaluation Research Based On System Methodology

In recent years,with the increasing demand for energy and the development of energy conservation and emission reduction,energy efficiency and clean utilization,the number of distributed energy projects is increasing.Distributed energy technology has been widely used in developed countries,but it started late in China and is still in the primary stage of large-scale development.Under the background of modern Internet energy,it is of great theoretical significance and application value to study the scheme configuration,evaluation criteria and operation optimization of distributed energy system.Firstly,based on the guiding ideology of system methodology,this paper analyzes and synthesizes the distributed energy supply system,studies the characteristics of system structure and function,and finds out the correlation between elements and between elements and environment.Combined with expert opinions,the evaluation indexes are determined,the internal and external factors and environment that affect the comprehensive evaluation results of the project are analyzed,and the quantitative calculation formula is given.Then the qualitative and quantitative indexes are unified through dimensionless and positive.Secondly,AHP and fuzzy comprehensive evaluation are used to establish the evaluation system.Then,in the fuzzy comprehensive evaluation model,the weight is determined by mathematical method and fuzzy comprehensive evaluation method,and the comprehensive evaluation result is obtained by calculating the matrix synthesis.Thirdly,computer technology and neural network algorithm are used to simplify the process of fuzzy comprehensive evaluation.BP neural network algorithm model is established,samples are selected for training,and the model is used to evaluate the distributed energy system scheme,and the results are compared with the fuzzy comprehensive evaluation results.Finally,collect the relevant information of the distributed energy projects that have been put into operation,use the established evaluation methods for empirical research and analysis,find out and summarize the problems of the examples,and try to give the corresponding solutions.
