摘　　要：风能作为一种典型的间歇性能源,有着低阻尼、弱惯量、缺乏频率支撑能力以及电压支撑能力弱等问题,大面积接入会给电力系统的稳定运行带来不小的挑战,加剧风能在电网中作为主力电源地位的不确定性。为此,文章提出了一种创新的风电并网稳定性解决方案——“一机一储”系统。该系统通过储能与风机的协同运行,旨在有效平滑功率和电压波动;在风能出力波动较大时,储能设备迅速响应,补充或吸收电能,发出无功,从而稳定电网的供需平衡,提升并网稳定性和可靠性。为验证该系统的实际应用效果,本文充分结合了风电场站的现场条件,采用了实验室仿真与风场样机实测相结合的双重验证方法。实验结果表明,“一机一储”系统在有效降低风电功率波动、提高电网稳定性的同时,还显示出更高的经济性和技术可行性,为风能在电网中的广泛应用提供了可能。Wind energy,as a typical intermittent energy source,presents multiple challenges such as low damping,weak inertia,insufficient capacity for frequency and voltage support.These issues pose significant challenges to the stable operation of power systems,particularly in scenarios involving a substantial connection to the grid,highlighting the uncertainty surrounding wind power's role as a potential primary power source.To address these challenges,this paper proposes an innovative stability solution for the grid connection of wind power-the"One Wind Turbine(WT)-One Energy Storage(ES)"system.This system aims to effectively smooth power and voltage fluctuations through the synergetic operation of energy storage and wind turbines.When wind energy output significantly fluctuates,the energy storage device promptly responds by either supplementing or absorbing electric energy and delivering reactive power,thereby stabilizing the grid's supply-demand balance and enhancing grid-connection stability and reliability.To validate the practical application effect of this system,a dual verification approach that combines laboratory simulations with field prototype testing was employed,to fully integrate the on-site conditions of wind farms.The experimental results demonstrated that the"One WT-One ES"system effectively mitigated fluctuations in wind power output and improved grid stability,showcasing enhanced economic efficiency and technical feasibility,which opens up possibilities for the widespread adoption of wind energy in power grids.
