Research On The Joint Planning Method For The Supply And Demand Side Under The Background Of Heating Reform

In recent years,in the face of the deepening energy and environmental crisis,a series of engineering projects have been promoted actively in China,such as electric energy substitution and heating reform,which makes the energy supply mode of users on demand side diversified and clean.Due to the differences of various energy supply modes,various reform projects are often planned and designed separately;on the other hand,the connection of the large-scale electric substitution load and heating reform load will have a profound impact on the planning of the energy systems,which will not only partly affect the engineering benefits of heating reform,but also challenge construction and development of integrated energy system on the supply side.In the environment of multi energy complementation and energy substitution,it is of great significance to consider the energy consumption of users on the demand side and the development of various energy systems on the supply side from a broader macro perspective,so as to improve the comprehensive utilization efficiency of energy and improve the environment.Aiming at the problem of heating renovation,this paper focuses on the decision-making method of heating renovation on the user side,energy system planning and modeling,and the joint planning method of the supply side and demand side.The main work is as follows:1)Firstly,this paper introduces the related theories of electric substitution,including the concept of electric substitution,the main types and ways of electric energy substitution,and the existing problems in electric energy substitution.Then,in view of the related problems in electric energy substitution,combined with the electric energy substitution project of "coal to electricity",the source of incremental electric load generated by "coal to electricity" is analyzed precisely,so as to guide that the clean energy such as wind power and photovoltaic can be absorbed by incremental electric load from "coal to electricity".2)In view of the problem of independent planning and lack of mutual coordination of all kinds of heating reform projects in China,combined with the theory of "coal to electricity" incremental power load distribution,a joint planning model of "coal to electricity" and "coal to gas" considering incremental power load distribution is constructed,which can give full play to the complementary advantages and collaborative benefits of various energy sources and effectively improve the comprehensive benefits of heating reform;Considered the influence of all kinds of energy supply constraints,based on the idea of staged planning,considering the changes of all kinds of energy supply capacity and clean energy installed scale in the planning cycle,a joint staged planning model of "coal to electricity" and "coal to gas" considering incremental power load distribution is established.The model is soived by vector order optimization algorithm.Finally,based on the example of heating reform project,the method in this paper is verified to carry the heating reform project forward orderly,promote the heating load to adapt to the development of energy,and effectively alleviate the environmental problem in China.This chapter focuses on the decision-making method of heating reform planning on the demand side,which provides the leading research and theoretical support for the analysis of comprehensive energy consumption behavior of users in chapter 4 and the modeling of supply-demand bilateral joint plannin.3)On the basis of previous research,the interaction between energy consumption behavior of users and various energy system planning is further analyzed.Considering the government as a decision-making body into the planning model,based on the game theory,a joint planning method for supply and demand side which takes into account comprehensive energy consumption behavior of users and policy orientation.First of all,the utility model of user’s energy consumption decision-making is established to analyze the user’s comprehensive energy consumption behavior.Then,the planning income model of various market entities in the integrated energy system is constructed respectively.And taking the environmental benefits of energy supply and reform as the optimization goal,the government’s assessment model of pollution emission from both sides of supply and demand is established.On this basis,based on the analysis of the game mechanism of various market entities,includingthe the user,the government and the integrated energy system,a two-level dynamic game model of supply and demand bilateral joint planning under the background of heating reform is constructed.Finally,the iterative search method is used to solve the model.The simulation results based on the standard examples show that the proposed method of joint planning for supply and demand side for heating reform fully considers the interaction between the user’s energy consumption behavior and energy system planning,which can realize the overall joint planning of the source and load side.Through the analysis of the user’s comprehensive energy consumption behavior,the load level on the demand side can be scientifically evaluated and predicted,which is effective to guide the integrated energy system to carry out more refined planning and construction,so as to improve the income of the integrated energy system.
