摘　　要：抽水蓄能机组是目前电力系统中最成熟、功率与能量容量最大的储能技术手段。凭借其灵活、大容量和较低的单位容量建造与运行成本,在构建高比例新能源的新型电力系统中发挥着越来越重要的作用。另一方面,长期以来抽水蓄能电站的运行模式主要集中于削峰填谷和系统备用并获取收益,单一且较低的回报无法体现抽水蓄能电站的经济与技术价值。在市场环境下并结合抽水蓄能电站的多种运行模式,研究了抽水蓄能电站提供削峰填谷、调频、备用、容量市场价值以及黑启动的经济价值测算评估模型。以抽水蓄能电站经济收入最大化为目标,构建了抽水蓄能电站参与能量市场、调频市场与备用市场多品种经济价值分析模型。进一步结合黑启动与容量价值等多种补偿政策,形成了抽水蓄能电站的多元化经济评价方法。通过开展多种电价场景的算例分析,研究抽水蓄能电站在不同电价波动水平下的经济收益差异,证明了所提出的抽水蓄能电站多元化经济评价方法的可行性。Pumped storage units are the most mature energy storage technology with the largest power and energy capacity in the current power system.With its flexibility,large capacity,and low construction and operation costs,it is playing an increasingly important role in power systems with high penetration of renewable energy sources.However,the operation of pumped storage power stations mainly focuses on peak load shifting and reserve to obtain revenue,and a single and low return cann’t reflect the economic and technical value of pumped storage power stations.In this study,the economic evaluation model,including peak load shifting,frequency regulation,reserve,capacity market,and black start,was built for pumped storage with diversified technical services considering the market environments.Aiming at maximizing the economic income of pumped storage power stations,a multi-variety economic value analysis model of pumped storage power stations participating in energy market,frequency regulation market and reserve market was established.Combined with the compensation policies of black start service and capacity market,a diversified economic valuation method for pumped storage was also proposed.Through example analysis under different scenarios,the revenue of pumped storage power plants under different price fluctuation levels were calculated and discussed,and the feasibility of the proposed diversified economic evaluation for pumped storage power stations was also verified.
