Low-Carbon Scheduling Model of Electricity-Gas-Heat Integrated Energy System Considering Ladder-Type Carbon Trading Mechanism, Vehicles Charging, and Multimode Utilization of Hydrogen

With the intensification of the energy crisis and the global greenhouse effect, it is particularly necessary to develop renewable energy generation and reduce carbon emissions. Therefore, a low-carbon economic dispatch model of the electricity-gas-heat integrated energy system (IES) considering ladder-type carbon trading mechanism (LCTM), vehicles charging, and multimode utilization of hydrogen is proposed. A multimode utilization of hydrogen model in the IES is established and the model energy flow is analyzed. The vehicles charging demand is simulated by Monte Carlo, which provides a model to calculate the carbon emissions of vehicles. In addition, the ladder-type carbon trading mechanism and integrated demand response are introduced to improve the system economy and low carbon performance. The simulation results demonstrate that the proposed model can significantly reduce carbon emissions and improve the economy of the IES.
