With the increasing shortage of fossil energy and environmental pollution in my country and the goal of "achieve carbon peaking and carbon neutrality",it is an irresistible trend to vigorously develop renewable energy and improve comprehensive energy utilization efficiency.The construction of the regional integrated energy system(RIES)can realize multi-energy complementarity,promote the effective conversion between various energy sources,and realize the efficient use of renewable energy.The use of integrated demand response(IDR)technology can achieve the effect of reducing the load peak-to-valley difference and improving the level of renewable energy consumption.The main research contents of this paper are as follows:In the first part,the basic theory of regional integrated energy system operation optimization based on integrated demand response is analyzed.Firstly,the basic structure of the integrated energy system is introduced,and the composition of the integrated energy system is analyzed;secondly,the two-layer optimization model used in this paper is considered,and the processing method of the two-layer optimization is discussed;then,the concepts and types of game theory are sorted out,analyzes the game model involved in this paper;finally,discusses the different types of comprehensive demand response.In the second part,a two-stage operation optimization method of regional integrated energy system based on integrated demand response is proposed.Firstly,the interaction framework and two-stage operation optimization process among system managers,integrated energy users and production capacity bases in the regional integrated energy system studied in this paper are introduced;The coupling characteristics are analyzed,and the IDR aggregation method is expounded;then,a two-layer Stackelberg game model based on the electricity price type IDR is constructed in the first stage.With the goal of minimizing operating costs,a two-layer Stackelberg game model with system managers as leaders and comprehensive energy users as followers is constructed,and a multi-swarm genetic algorithm is used to solve the model.In the first stage of optimization,the Stackelberg game is used for optimization.method,which can realize the common pricing of system managers and comprehensive energy users.Finally,a second-stage alliance game model based on incentive-based IDR is constructed.The search algorithm solves the model.In the second stage of optimization,the incentive-based IDR strategy is used to form a good mutually beneficial relationship between the production capacity base and the comprehensive energy users.In the third part,the simulation results of regional integrated energy system operation optimization based on integrated demand response are discussed.Firstly,the basic data and parameters of the calculation example are given;secondly,the simulation analysis is carried out,and the operation optimization results of the system manager,the comprehensive energy user and the production capacity base after the two-stage operation optimization are given,and the simulation results in different stages are compared.The analysis proves that the two-stage operation optimization can improve the economic benefits of the system manager and the wind power grid connection rate of the production capacity base,and reduce the operation cost of the comprehensive energy users.
