Research On Evaluation System And Method For Sustainable Development Of Distribution Network

With the current world focusing on sustainable development,people attach more importance to the protection of the ecological environment.The development of the power industry is the basis for the development of every other industry.It is of great significance to study its sustainable development.From the perspective of national strategy,the sustainable development of the power industry can be roughly divided into energy supply side,power generation side,distribut ion network side and consumer side.Generation,transmission,transformation,distribution,and use of electricity are the main components of a well-known power system.From the current situation in China,compared with other parts,the distribution networ k has fewer control means.The development of electrical-side equipment is still relatively backward compared to developed countries,there are great restrictions on the reliable and safe operation of the distribution network.the exploration of the sustainable development of the distribution network has a good application prospect for improving the composition of global energy and reducing global warming.The main work done in this article is as follows:(1)Establish a sustainability evaluation index syst em for the distribution network.Through the PSR "stress-state-response" model,a series of indicators were selected from the reliability,economics,flexibility,user efficiency and environmental pollution degree of the distribution network,and a four-tier indicator system was constructed,The complex four-tier indicator system has been simplified.(2)Establish a sustainability assessment model for the distribution network.A comprehensive evaluation method is adopted to establish a sustainable developme nt evaluation model through the DEA model,the super-efficiency DEA model,and the improved super-efficiency DEA model.Achieve full ranking of sustainability assessments for all evaluation units.(3)An example calculation and analysis of the sustainabili ty assessment of the distribution network is performed to verify the scientificity and rationality of the sustainability assessment system of the distribution network proposed in this paper.
