Research On The Optimal Operation Method Of Integrated Energy System Considering Integrated Demand Response

Under the background of "carbon peaking and carbon neutrality",an integrated energy system that can realize the coordination and complementation of cooling,heating,electricity and gas is an inevitable trend of energy development.The integrated energy system can not only effectively consume renewable energy and improve energy utilization,but also the operation of the integrated energy system is low-carbon and environmentally friendly,which has gradually become a research hotspot.As the supply and demand sides of the integrated energy system have higher and higher requirements for the reliability,economy,and environmental protection of energy supply,how to take into account the interests of both the system and users,and reduce environmental pollution on the premise of ensuring the quality of energy supply The huge challenges that need to be faced in the process of developing an integrated energy system.In order to improve the economy and low carbon of the integrated energy system,this paper focuses on the optimal operation method of the integrated energy system considering the integrated demand response.Firstly,the architecture of the integrated energy system and the main energ y equipment in the system are introduced,and then an optimized operation model of the integrated energy system considering the integrated demand response and stackelberg game is established.With the system side as the main body and the user side as the slave body,a stackelberg game interaction model is formed,and at the same time,the system’s energy price for users,the user demand response plan and the output of the energy conversion equipment in the system are optimized.Finally,the particle swarm algorithm is used for simulation verification.The calculation example shows that the model can realize the flexible interaction between supply and demand,optimize the output of energy equipment in the system,and can take into account the interests of both supply and demand,and improve the economy.On the basis of the above stackelberg game framework,a carbon trading mechanism is introduced,and a comprehensive energy system optimization operation method considering carbon trading and comprehensive demand response is proposed.Study the impact of the ladder-type carbon trading mechanism on system costs and energy equipment output,and analyze the impact of market carbon trading prices on carbon emissions.The research results show that this method can eff ectively achieve the effect of emission reduction,and after considering the comprehensive demand response,the carbon emission cost of the system,the total cost and the output of energy equipment inside the system have also been further optimized.The in crease will cause the system to favor the use of gas-fired equipment such as cogeneration units with lower carbon emissions per unit.
