摘要:

“碳达峰、碳中和”背景下,新能源发电将成为未来电力系统中的主要发电形式。然而,其随机性与波动性增加了电网不同时间尺度上的运行备用需求。抽水蓄能作为成熟的储能技术之一,具有调节速度快、容量大等优势,在电网辅助服务中的作用已备受重视。然而,抽蓄电站在电能量市场与各类辅助服务市场中的运行策略、收益最大化问题还有待深入研究。为此,本工作在电力市场环境下建立了抽蓄电站参与电能量市场与多时间尺度备用市场的优化决策模型,并着重分析了备用补偿价格对其运行策略的影响,为抽蓄电站参与电力市场的运行决策提供了解决方案。算例分析表明:抽蓄电站通过提供备用服务能够明显提高其运行收益;并且,抽蓄电站提供多种备用时的总收益明显高于提供单一备用时的收益。本文算例分析中,提供多种备用的总收益至少提高了44.37%。

Abstract:

In the background of peak carbon emissions and carbon neutrality, renewable energy generation will become the main generation form in future power systems. Simultaneously, randomness and volatility increase the reserve requirement in different time scales. Pumped-storage power station (PSPS), a mature type of energy storage, has the advantages of fast regulation speed and large capacity, and it has increasing importance in the aspect of ancillary services. Trading off the benefits of energy storage in the energy market and the multiple time-scale reserve market to maximize its benefits is an important issue for PSPS waiting to be addressed. In this regard, this paper establishes an optimal decision-making model for PSPS to participate in the energy market and the multiple time-scale reserve market. The impact of reserve compensation prices on the operation strategies is further analyzed. This work provides a solution for PSPS to participate in the electric energy market. Case studies show that the total revenue of PSPS is significantly increased through providing reserve service. The total revenue of PSPS when providing multiple time-scale reserves is higher than that when providing a single reserve service. In the test case, the total revenue of PSPS when providing multiple time-scale reserves is increased by 44.37% at least.
