弃风、调停火电还是开发抽水蓄能?——抽水蓄能电站低谷调峰性能研究

摘要

Pumped storage units have various operation modes such as pumping and power generation,and the switching between different operating conditions is flexible.The technology characteristics of pumped storage unit,making it a good load power supply,the optimization of system power supply structure,promote clean renewable energy sources such as wind power large-scale development plays a very important role.This article obtains from the power system operation rule,through the establishment of a rigorous mathematical model,specify regulating principle,the low value of pumped storage unit,and abandon the wind,mediation thermal power unit and the development relations between the technical and economic comparison of pumped storage%抽水蓄能机组能够承担抽水和发电等多种运行任务,而且不同运行工况间启停转换灵活.抽水蓄能机组的这一技术特性,使其成为优良的调峰电源,在优化系统电源结构、促进风电等清洁可再生能源大规模开发方面发挥着十分重要的作用.本文从客观分析电力系统运行规律入手,通过建立较为严谨的数学模型,具体说明抽水蓄能机组的低谷调峰原理、价值,以及弃风、调停火电机组和建设运行抽水蓄能之间的技术、经济对比关系,旨在为丰富抽水蓄能发展理论、科学决策抽水蓄能电站运行方式提供理论支撑.
