摘要(Abstract)：

由于分布式电源的输出功率间歇性和波动性,传统电力电子逆变设备的低惯性和欠阻尼特性可能对电网稳定性带来不利影响,为了提高系统维持稳定性和抑制振荡所需的惯性和阻尼,利用考虑汽门与励磁协调控制的三阶同步发电机模型,设计了基于耗散Hamilton能量控制的虚拟同步发电机控制。并将ADRC技术运用到虚拟同步发电机控制中来消除控制系统内部的电压电流控制耦合项。最后,利用Dig SILENT/Power Factory仿真软件仿真分析并验证了所提的控制算法可以明显提高系统鲁棒性、抑制振荡、提供虚拟惯性和正阻尼以及消除参数摄动和耦合。

关键词(KeyWords)： 并网逆变器;虚拟同步发电机;耗散Hamilton系统;自抗扰控制;电力系统稳定性
