摘　　要：在“以大代小”政策鼓励下,老旧风机逐步迎来退役高峰。采用老旧风机改建重力储能系统,可同时解决老旧风机退役问题和风电储能需求缺口,具备良好的经济社会生态效益。以1.5 MW老旧风机为例,分析风机塔筒改建重力储能系统的容量潜力,探讨储能系统的功率和运行时长选择,改建后的储能系统容量可达6.67 kWh,系统功率可选范围为20 kW至2 MW,相应储能时长为20 min至10 s。阐明老旧风机改建重力储能相比其他短时储能形式的建设成本优势,并讨论运行成本和收益情况,为新能源和储能技术的发展提供新思路和新模式。Encouraged by the policy of"replacing small ones with large ones",old wind turbines are gradually ushering in their retirement peak.Using old wind turbines to rebuild gravity energy storage systems can simultaneously solve the problem of decommissioning old wind turbines and the gap in wind power energy storage demand,and has good economic,social and ecological benefits.Taking an old 1.5 MW wind turbine as an example,the capacity potential of the wind turbine tower to be rebuilt into a gravity energy storage system is analyzed,and the power and operating time selection of the energy storage system are discussed.The capacity of the renovated energy storage system can reach 6.67 kWh,and the system power can be selectable.The range is 20 kW to 2 MW,and the corresponding energy storage time is 20 minutes to 10 seconds.The construction cost advantages of retrofitting gravity energy storage with old wind turbines compared with other short-term energy storage forms are clarified,and the operating costs and benefits are discussed,providing new ideas and models for the development of new energy and energy storage technologies.
