考虑碳交易和电动汽车充电负荷的工业园区综合能源系统调度策略

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

  • 摘要: 为实现“双碳”目标,优化工业园区多能利用形式,提出了一种工业园区综合能源系统调度策略。首先,针对工业园区能源多元化的特点,设计汇聚电、热、氢能源的工业园区综合能源系统;然后,基于工业园区的负荷可调节能力差的特性,将电动汽车作为可灵活调整的柔性负荷加入综合能源系统的调度过程;进而搭建以系统总运行成本最小为目标函数,考虑碳交易机制和电动汽车充电负荷调节比例的经济性数学模型;最后,在MATLAB中调用CPLEX求解器对4种对比方案进行求解及分析。结果表明:所提出的调度策略中,引入碳交易机制能够在日运行中降低4.5%的碳排放量,调整30%以下的电动汽车负荷比例能够降低1.54%的运行成本。在清洁能源持续发展和未来技术发展趋势下,成本将会进一步降低,该研究可为工业园区能源系统的优化调度提供参考。

     

    Abstract: 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.
