Research On Cost Optimization Of Distributed Energy System

With the continuous growth of energy demand and the increasing demand for green ecological environment,the importance of new energy has gradually become prominent due to the constraints of energy and environmental issues on the sustainable development of the economy and society.The use of renewable energy in distributed energy systems has the advantages of high efficiency,reliability and environmental protection,and has great development potential.However,in the development process of distributed energy system,the problem of high cost restricts its development.At present,domestic and foreign researches focus on the cost of cost optimization design research and the cost from the financial point of view is different,and it is not easy to collect and optimize the cost in actual management.Therefore,analyzing the cost structure of the distributed energy system and discussing its cost optimization method has important practical significance for promoting the development of distributed energy.Especially in the context of chinese "carbon neutral" strategic goal,fully tapping the cost optimization potential of distributed energy systems,reducing system operating costs will greatly promote the realization of the "carbon neutral" goal.The paper focuses on the cost optimization of the distributed energy system.According to the idea of "factor-optimization-strategy",analyzes the cost composition and influencing factors of the distributed energy system,researches the cost optimization method,and further proposes relevant suggestions.First,it explains the importance of the research on cost optimization of distributed energy systems,and summarizes the connotation of cost optimization and related research at home and abroad;secondly,it analyzes the architecture and cost-related theories of distributed energy systems,and discusses the cost optimization.Manage the feasibility of using distributed energy systems,combine the current development status of distributed energy at home and abroad,use cost theory to analyze the cost composition of distributed energy systems,and sort out the influencing factors of costs;on this basis,target operating costs Constructed a distributed energy system cost optimization model based on demand load feedback,and solved it with particle swarm algorithm.Through the analysis and comparison of calculation examples in different scenarios,the effectiveness of the model was verified.The energy system has played a positive role in reducing costs and increasing efficiency.Finally,based on the development status of distributed energy in China,the analysis of the cost structure of distributed energy system and its influence,and the results of calculation examples,research recommendations are put forward.The research results of this paper show that the cost optimization of the distributed energy system can be carried out,and the optimization method in response to load feedback can reduce the operating cost of the distributed energy system by 4.54%,thereby improving the overall efficiency of the enterprise’s production process.The cost optimization model of the distributed energy system based on demand load feedback optimizes the operation of the equipment in the system can effectively reduce the operating cost of the system;compared with the grid-connected operation mode without the Internet,the distributed energy system in the grid-connected mode The operating cost can also be effectively reduced.The surplus power grid can improve the operating efficiency of the distributed energy system and reduce the operating cost level;for the current problems facing the development of the distributed energy system,the government and enterprises need to rely on policy control and technological improvement,comprehensive cost management and other aspects to solve and improve.
