The existing community integrated energy system dispatching strategies has the disadvantages of high cost,environmental pollution and low energy utilization rate.Therefore,a low-carbon economic optimization model of a community integrated energy system that considers the power to gas and carbon trading mechanism is proposed.Firstly,the heat release characteristics of the methanation link in the process of power to gas and its influence on the optimal operation of the system are analyzed.Secondly,a ladder-type carbon trading mechanism of rewards and punishments for community integrated energy system with compensation factors is established to constrain the carbon emissions.Finally,an optimal scheduling model of the community integrated energy system is established with the goal of minimizing the operation cost,energy abandonment power and carbon emissions,and the multi-objective optimization calculation is carried out.The results show that the proposed optimization model reduces the total cost,energy consumption and carbon emissions by 15.4%,98.3%and 19.7%,respectively.Therefore,the proposed scheduling model can improve the energy utilization efficiency and economy,and reduce the carbon emissions of the community integrated energy system effectively.
