摘　　要：储能系统(Energy Storage System,ESS)作为柔性负荷,可实现对风电、光伏等削峰填谷而逐渐成为研究热点。文章研究了虚拟同步发电机控制(Virtual Synchronous Generator,VSG)在储能系统中的应用,提出了一种虚拟阻尼前馈的VSG控制结构,在不影响VSG阻尼特性的前提下,精准实现了储能系统的一次调频特性。最后,仿真结果证明了所提策略的可行性。The energy storage system(ESS),as a kind of flexible load which can realize wind power and photovoltaics,has gradually become a research spot.The article studies the application of Virtual Synchronous Generator(VSG)in the energy storage system.It proposes a virtual damping feedforward based VSG control structure,which accurately realizes the primary frequency modulation characteristics of the energy storage system without affecting the VSG damping characteristics.Finally,the simulation results prove the feasibility of the proposed strategy.
