Optimal Scheduling of Integrated Energy Systems Considering Low-carbon Demand Response

Integrated energy systems face greater pressure to reduce emissions, and with the development of smart grids, the participation of demand-side resources in system scheduling can further reduce system carbon emissions. This paper proposes an optimal scheduling method considering low-carbon demand response. Based on the dynamic carbon emission measurement model of the unit, a low-carbon economic dispatch optimisation model of the power system is established, the real-time carbon emissions and carbon emission cost on the customer side are calculated, the demand response with carbon price as a signal is considered, a low-carbon economic optimal dispatch model is established, the load distribution is optimised to further reduce the system carbon emissions, and the final dispatch scheme is solved to obtain the final dispatch scheme. Finally, the IEEE 14 nodes are used as an example to calculate and analyse the system carbon emissions and total operating costs.
