Low Carbon Scheduling of Integrated Energy Systems Considering Stepped Carbon Trading and Demand Response

With the in-depth reform of the energy market, making full use of demand response resources has become a factor that cannot be ignored in the low-carbon operation of integrated energy system. In this regard, a low-carbon dispatching strategy of integrated energy system considering carbon trading and dual response of supply and demand is proposed. Firstly, for the multiplicity and dispatchability of the integrated energy system, a step-type carbon trading model of the integrated energy system is constructed, and based on this, a dual-response model of supply and demand is constructed and a response compensation mechanism is proposed; secondly, for the uncertainty of renewable energy, an optimal dispatching model is established with the objective function of minimizing the sum of operation cost, demand response compensation cost and carbon trading cost. Finally, the CPLEX toolbox is used to solve the proposed model. Through different scenarios of calculations, the impact of the dual response strategy of supply and demand and the stepped carbon trading mechanism on the operation optimization of integrated energy system, energy saving and emission reduction is analyzed, and the simulation results verify the economy and low carbon of the proposed model and strategy.
