Scheduling Strategy of Industrial Parks Integrated Energy System Considering Carbon Trading and Electric Vehicle Charging Load

To achieve the goals of carbon peaking and carbon neutrality, and to optimize the multi-energy utilization form in industrial parks, an integrated energy system scheduling strategy for industrial parks is proposed. Firstly, according to the characteristics of energy diversification in industrial parks, a comprehensive energy system of industrial parks including electricity, heat and hydrogen energy is designed. Then, according to poor load adjustment ability of industrial parks, electric vehicles (EV) are added to the scheduling process of the integrated energy system as flexible loads that can be adjusted flexibly. Then, the carbon trading mechanism and the EV charging load adjustment ratio are taken into consideration, and an economic mathematical model with the objective function of minimum system total operating cost is built. Finally, the CPLEX solver is called in MATLAB to solve and analyze the four comparison schemes. The results show that, in the scheduling strategy proposed in this paper, introducing carbon trading mechanism can reduce the carbon emission by 4.5% in daily operation, and adjusting the load ratio of EV below 30% can reduce operating costs by 1.54%. With the continuous development of clean energy and future technology development trends, the cost will be further reduced. The research in this paper can provide a reference for the optimal scheduling of energy systems in industrial parks. © 2023 Science Press. All rights reserved.
