Design And Application Method Of Integrated Energy System

With the development of economy and the improvement of people's living standard,the demand for electricity is increasing day by day,we cannot rely on fossil fuels alone to meet our growing energy needs.As the main component of the energy Internet,the integrated energy system realizes the transformation of various forms of energy and the interconnection of various energy networks,which is one of the key research directions in the future.Based on the actual energy demand of the resettlement area and the local energy resource endowment,this paper constructs a comprehensive energy utilization system in coordination with the construction target.Make full use of local renewable energy resources,optimize the energy structure of resettlement area,improve efficiency,reduce the input and the total energy consumption,to explore a variety of flexible type energy trading patterns,to promote the healthy development of new energy industry chain and business model innovation,establish a "clean zero carbon,safe and efficient,cooperative sharing,green travel" comprehensive energy utilization demonstration zone.Finally,the research direction and future research emphasis of integrated energy system are prospected and analyzed.This paper mainly analyses the resources and current situation of the resettlement area.Through the calculation and analysis of geothermal resources,lighting resources,power resources and buildings in the resettlement area,the demand of heating virtual heat load,heating heat demand load and cooling heat demand load are calculated and analyzed.Combined with the calculation of photovoltaic power generation system,the comprehensive energy demand is forecasted at last.At the same time,the layout of comprehensive energy in resettlement area is planned.Based on the analysis of the present situation of the resources in the resettlement area,facing the actual energy demand of the resettlement area,considering the energy resources and basic conditions comprehensively,the rational energy planning is formulated,and the comprehensive energy utilization system coordinated with the construction objectives is constructed.In view of the users' multiple energy demand,a coordinated planning of multi energy complementarity is carried out.Based on the "Internet+",through the user energy efficiency management system,energy big data and intelligent operation and maintenance system,a comprehensive energy utilization system of source,network,storage and storage is formed,which lays the technical support for promoting the depth and breadth of the comprehensive utilization of new energy.Finally,a comprehensive energy information management platform is constructed.Through deep coupling of information and energy and wide integration of multi-energy systems,it provides data base and decision support for integrated energy services.The platform will integrate integrated energy infrastructure planning and architectural design,introduce technologies such as ubiquitous Internet of Things,intelligent aggregation of energy data,multi-energy collaborative optimization scheduling,BIM modeling and analysis,and carry out integrated energy production,transmission,consumption,management and control,so as to achieve efficient production,flexible control and intelligent utilization of various forms of energy.It comprehensively reflects the energy application situation in the resettlement area,and improves the coordination ability of energy supply and demand in the resettlement area.
