Optimal Scheduling Strategy of Park Integrated Energy System Considering Ladder Carbon Trading Mechanism and Demand Response

In order to improve the energy utilization rate of the integrated energy system in the park, further limit carbon emissions, and make it realize low-carbon economic operation, an optimal scheduling strategy of the multi-energy coupling integrated energy system taking into account the demand response and the stepped carbon trading mechanism is proposed. Considering the flexible response capability of multiple loads on the demand side, a demand response model with electricity-heating-cooling load is constructed; The organic Rankine cycle is introduced for waste heat power generation to make the output of cogeneration more flexible; Combined with the step-type carbon trading mechanism, further constrain the system's carbon emissions. The results show that considering the demand side multi-load demand response and the stepped carbon trading mechanism can effectively reduce the carbon emissions of the system and improve the system economy.
