摘要(Abstract):
抽水蓄能(以下简称“抽蓄”)电站是对电力系统进行调节的重要方式之一,对电力系统的安全和经济稳定运行具有重要的意义。为此,介绍抽蓄电站经济效益分析的研究现状,提出抽蓄-火电联合运营静态、动态经济效益分析方法,并以某区域4×300 MW抽蓄电站和2×1 000 MW火力发电厂联合运营为例,分析两者协调配合产生的经济效益,给出抽蓄机组调峰填谷、调频调相和事故备用等经济效益的详细计算方法,为抽蓄-火电联合运营提供合理依据。
Pumped storage power plants are one of the significant means for regulating power systems, holding crucial importance for their secure, economical, and stable operation. The current research status of economic benefit analysis of pumped storage power plants is introduced, and the static and dynamic economic benefit analysis method of the collaboration between a pumped storage power plant and a thermal power plant is put forward. Moreover, the collaboration between a 4×300 MW pumped storage power plant and a 2×1 000 MW thermal power plant in a region is taken as an example to analyze the economic benefits resulting from their collaboration. The detailed calculation methods for the economic benefits of pumped storage units such as peak shaving and valley filling, frequency modulation, phase modulation, and contingency reserves are presented. These calculations can serve as a rational foundation for the collaboration between pumped storage power plants and thermal power plants.
