Comprehensive energy system optimization strategy based on stepped carbon trading mechanism

In the context of double carbon, the park’s integrated energy system can reduce carbon dioxide emissions and improve energy utilization while ensuring users’ energy consumption. It is an effective way to achieve the goal of 3060. Realizing low-cost and low-emission industrial parks is an urgent and realistic problem. This paper considers the economy and low carbon of the industrial park. Consider improving the carbon trading mechanism into a ladder and fully consider the energy consumption characteristics of each equipment. A low-carbon economic scheduling model of the park’s comprehensive energy system to minimize the daily operating cost is built, which is solved using the CPLEX commercial solver. By setting different scenarios, the effectiveness of the proposed stepped carbon trading mechanism to limit the total carbon emissions of the park is verified.
