摘要(Abstract)：

虚拟同步电机(virtual synchronous generator,VSG)在响应电网负荷波动时需要储能单元提供惯性功率。储能单元的荷电状态(state of charge,SOC)能够反映储能单元提供惯性功率的能力从而为VSG相关参数的取值提供参考。此外,为保证系统频率的稳定以及VSG系统的动态响应性能,提出VSG的虚拟转动惯量和阻尼系数的综合取值区域。同时,考虑储能单元荷电状态双向特性,分析综合取值区域的变化情况。在此取值区域内,能够防止储能单元功率超限的同时兼顾系统频率稳定和VSG动态响应性能。最后,使用Matlab/Simulink搭建相关仿真模型,验证所提方案的有效性。
