Research On Low-carbon Operation Strategies Of Integrated Demand Response Considering User’s Complex Response Characteristics

To efficiently accommodate large-scale new energy,the energy system is developing towards the direction of integrated energy systems in industrial parks that feature multienergy collaboration and source-load interaction.In order to ensure the safe,stable,and economical operation of the integrated energy system in industrial parks,comprehensive demand response technology has emerged.Comprehensive demand response refers to the integrated energy service provider in industrial parks guiding users to participate in the operation and regulation of the system through multi-energy conversion technology and economic means,thereby ensuring the supply-demand balance of the integrated energy system in industrial parks.However,existing research on comprehensive demand response has not considered the impact of coupling effects between energy and carbon emissions on incentive prices,nor has it studied the impact of user complex response characteristics and carbon emission costs on energy prices.Therefore,this thesis studies the comprehensive demand response operation strategy considering the energy-carbon coupling incentive mechanism and the low-carbon operation strategy of comprehensive demand response under the influence of user complex response characteristics.Firstly,this thesis clarifies the basic operational architecture of the integrated energy system in industrial parks.Based on this,the entities participating in demand response are analyzed,the information exchange method and energy flow direction between entities are clarified,and mathematical models of typical energy conversion equipment are established to lay the foundation for subsequent research.Secondly,this thesis proposes a comprehensive demand response operation strategy considering the energy-carbon coupling incentive mechanism for users.By analyzing the coupling effect between energy and carbon emissions within the integrated energy service provider,the calculation method of carbon emissions is determined,and an incentive mechanism considering the energycarbon coupling effect is proposed.Based on this mechanism,a user model including response dissatisfaction cost and an integrated energy service provider model including carbon trading cost are established,and an improved particle swarm algorithm is used for iterative solution.Simulation results confirm that the proposed strategy can not only reduce user response dissatisfaction but also decrease the system’s carbon emissions.Subsequently,a low-carbon operation strategy for comprehensive demand response considering user complex response characteristics is proposed.A dynamic pricing mechanism for energy sales oriented towards integrated energy service providers is established based on the characteristic of user response dissatisfaction,and an incentive-type and price-type coordinated comprehensive demand response model is constructed.Finally,the CPLEX is used for iterative solution of the model.Simulation results confirm that the proposed strategy can achieve mutual benefit for multiple parties,ensure both economic efficiency and low-carbon emissions,and promote the safe and low-carbon economic operation of the integrated energy system in industrial parks.
