Source-load Collaborative Optimization Combining Stepwise Carbon Trading and Demand response
In order to realize low-carbon economic operation of multi-energy complementary regional integrated energy system,this paper proposes a source-load collaborative optimization operation method integrating stepwise carbon trading demand response.Firstly,it introduces the stepwise carbon trading mechanism and power-to-gas equipment to improve the absorption level of the renewable energy sources on the source side and reduce carbon emissions.Secondly,on the load side,an excitation demand response with electric-gas-thermal multi-energy coupling considering user satisfaction is introduced,and the peak shaving and valley filling of multiple loads is realized by combining the peak shaving benefits.Based on this,the paper establishes an optimal operation model of regional electricity-gas-heat integrated energy system considering carbon trading and demand response.Finally,the example results show that the proposed dispatching model can optimize the electric-gas-heat load curve and reduce the carbon emissions of the system,and realize the coordinated carbon reduction and economic operation of the source-load of the regional integrated energy system.
