在“双碳”背景下,为增进能源效益,改善设备运营的弹性,进一步减少系统运行的碳排放水平,提出了一种低碳经济运作策略。首要将综合能源系统融入碳交易市场,引入分层碳交易机制以引导系统控制碳排放；然后将将新能源发电机组接入综合能源系统,并且引入抽水蓄能系统和火电机组发电系统用以辅助系统电力调度增加新能源消纳能力；最后使用cplex求解器根据预测负荷和各项机组的运行约束求解出低碳运行调度策略。应用上述方法对综合能源系统进行仿真分析,结果表明,在碳交易机制的影响下,可以改进运行策略,降低系统的碳排放,并且抽水蓄能系统可以大大综合能源系统提高新能源的消纳能力。

In the context of the "dual carbon" framework, a low-carbon economic operation strategy is proposed to enhance energy efficiency, improve the flexibility of equipment operation, and further reduce the carbon emission levels of system operation. The primary approach involves integrating the comprehensive energy system into the carbon trading market and introducing a tiered carbon trading mechanism to guide system control of carbon emissions. Next, new energy generation units are integrated into the comprehensive energy system, and pumped storage energy systems and gas turbine power generation systems are introduced to assist in system power scheduling and increase the integration capacity of new energy sources. Finally, using the CPLEX solver, a low-carbon operational scheduling strategy is solved based on forecasted loads and operational constraints of various units. The application of the above methods to simulate and analyze the comprehensive energy system shows that, under the influence of the carbon trading mechanism, operational strategies can be improved to reduce the system"s carbon emissions. Additionally, pumped storage energy systems can significantly enhance the integration capacity of new energy sources in the comprehensive energy system.
