摘要
随着“双碳”目标的提出,电力系统低碳化转型以及新能源高比例渗透已成为必然趋势。然而,高比例新能源并网给电力系统灵活性运行带来了更大的挑战。因此,调度侧需具备充裕的运行灵活性以平抑净负荷波动。该文以含碳捕集电厂的气-电耦合综合能源系统为对象,提出了一种计及灵活爬坡需求的低碳经济调度模型。首先,计及了电力系统、天然气系统和碳捕集电厂的运行约束,构建了计及碳排放成本的低碳经济模型。然后,考虑了发电机组与碳捕集电厂提供运行灵活性爬坡服务,建立了计及灵活爬坡产品的综合能源系统低碳经济调度模型。最后,算例测试定量分析了碳价对于综合能源系统低碳调度决策的影响,量化了燃气机组与碳捕集电厂的运行灵活性。
With the proposal of the "carbon emission and carbon neutrality" goals,the low-carbon transition of power systems and the high penetrations of renewable energy have become an inevitable trend.However,the integration of intermittent renewable energy poses challenges to the flexible operations of the power systems.Therefore,dispatching the conventional generators with sufficient ramping capability is required to accommodate net load fluctuation.This paper proposes a low-carbon economic dispatching model of gas-electric integrated energy systems,which takes flexible ramping services into account.First,a low carbon economic model is built considering the operating constraints of the power system,the natural gas system and the carbon capture power plant.Second,taking the flexible ramping products provided by both power generators and carbon capture power plants into account,a low-carbon economic scheduling model of integrated energy system with the flexible ramping products is established.Finally,numerical results quantitatively analyze the impact of carbon prices on the low-carbon dispatching decisions of the integrated energy system.Additionally,the operating flexibility of the gas turbines and the carbon capture power plant is quantified.
