Comprehensive Energy System Operation Model And Cost-benefit Analysis Considering Main Body Characteristics

With the rapid development of the national economy and the continuous innovation of science and technology,the demand for energy is gradually increasing.However,traditional fossil energy is a non-renewable resource and cannot be continuously supplied.The environmental and climate issues that come with it have become low development in the future.A major hurdle that must be overcome on the road to the carbon economy.In this context,deepening the global energy structure revolution,improving the efficiency of traditional fossil energy utilization,vigorously developing non-fossil energy,and building a low-carbon and energy-saving new energy system have become the future energy development trend of China and the world.The integrated energy system is an inevitable product of this trend,and it is also the only way to achieve energy transformation,clean,high-efficiency,low-carbon and environmental protection.The reliable policy support of the integrated energy system,efficient energy utilization and strong low-carbon environmental protection advantages have attracted many participants.In order to grasp the new business opportunities during the energy transition period and adapt to the new situation of energy market development,the State Grid Corporation of China,New energy power generation companies,gas companies and other energy companies have joined the army to explore and practice the transformation of the integrated energy system.However,there are many participants in the integrated energy system,and most of them do not fully understand the environmental factors that enterprises face in the process of integrated energy system transformation,which leads to difficulties in transition.At the same time,the choice of operation mode is an important link for enterprises to develop integrated energy system business.Therefore,this article focuses on the main participants of the integrated energy system,the system investment and operation mode,and the economic benefits of the integrated energy system.First,it deeply analyzes the domestic and foreign research status of the integrated energy system in terms of the participants,operation mode and cost-effectiveness,and summarizes the comprehensive energy system.The main participants in the energy system are the State Grid Corporation of China,distributed new energy power generation companies,and natural gas companies.Taking these three entities as representatives,it analyzes the internal and external environment facing the development of integrated energy business,refines the advantages and disadvantages,and proposes an analysis method for the investment and operation mode of the integrated energy system based on the characteristics of the entity,and constructs an operation based on the characteristics of the entity.The evaluation index system of the applicability of the model is adopted,and the analytic hierarchy process is used to assign weights to different participants,and to provide participants with a qualitative analysis method for the choice of operating modes.Then it analyzes the cost and benefit composition of integrated energy,and then based on the cost-benefit composition of the integrated energy system,four models of independent investment+independent operation,independent investment+commissioned operation,cooperative investment+cooperative operation,and cooperative investment+commissioned operation are proposed.Corresponding cost-benefit accounting model,and gives the economic benefit analysis method of the integrated energy system.Finally,take the comprehensive energy system of Park A as an example.First,analyze the applicability of the four investment and operation modes to the three participating entities.From the perspective of the degree of applicability,the models are optimized for each entity,and then the participating entities and operating modes are selected.Starting from two perspectives,based on the cost-benefit analysis of the participating entities under different operating modes,the three participating entities are selected from the economic benefit dimension,and the final model selection is given from the perspective of the entities in the two dimensions.And development suggestions,from a long-term perspective,have certain practical significance for the development of the integrated energy system as a whole and the participants.
