Value Evaluation Model And Application Of Integrated Energy System Based On Value Network

At present,the trend of fossil energy supply is tightening,energy security problems appear frequently,and carbon emission pressures are increasing.It is urgent to optimize energy structure,improve energy supply quality and comprehensive energy utilization efficiency,reduce energy waste,and ensure the sustainable development of human society's energy..Integrated Energy System(IES)is the proposed integrated energy system.Its main features are the unified and coordinated supply of various forms of energy such as electricity,heat and gas.It realizes the coupling of different types of energy in the source-network-load relationship.Diversified operation modes,high efficiency and low carbon,and high renewable energy consumption rate.In view of the problems of long construction period,high energy consumption level,low technical level and improper operation management of existing energy systems,upgrading existing energy systems through information technology and "Internet+" means can improve system integration.Use efficiency to form a new value driver to better meet user needs.This paper starts with the new value source under the Internet thinking,puts forward the value proposition of the integrated energy system oriented by the user demand,and then focuses on constructing the value network model of the integrated energy system from the value pattern,value creation and value transfer of the integrated energy system.The core content of this idea is:based on the development experience of domestic and international integrated energy system demonstration projects,improve the basic organizational structure of the integrated energy system,and drive the value orientation of each network node in the integrated energy system driven by the user's energy demand.The internal value interaction of network relationships systematically promotes overall value creation and value appreciation.First,it summarizes the research trends of integrated energy systems,value network theory and value assessment methods,analyzes the development status of integrated energy systems at home and abroad,summarizes experiences and provides theoretical basis for the development of thesis work.Second,through the comprehensive energy The system connotation,the energy system structure of the typical demonstration project and the network connection mode of the integrated energy system are studied,the value source of the integrated energy system and its influencing factors are analyzed,and the value of the system is defined.Third,from the value proposition,value creation and Three aspects of value acquisition discuss the formation logic of the integrated energy system value network and model it based on e3-value software.Combined with specific case analysis,the research ideas of comprehensive energy system value assessment are put forward.Fourthly,the comprehensive energy system value evaluation system is constructed from three aspects:grid side,integrated energy system and user side,and IES comprehensive based on improved TDAHP-cloud model is established.Value evaluation model;Fifthly,taking the integrated energy system for the microgrid in the park as an example,constructing and evaluating the integrated energy system with different structures,based on the evaluation results,from the program configuration,energy policy,interaction mechanism,energy management,etc.The paper puts forward the countermeasures and suggestions for the realization of the value of the integrated energy system.The research results in this paper can provide theoretical basis for the configuration of integrated energy systems and the path of consumption of renewable energy.
