摘要(Abstract)：

传统的虚拟同步发电机(virtual synchronous generator,VSG)有功控制调节虚拟惯量和虚拟阻尼无法实现系统各动态性能指标的一致性改善,为此提出基于角频率偏差补偿的VSG有功控制。该控制策略是在原输出有功功率上叠加角频率的偏差补偿,加快VSG跟踪有功功率指令的速度,减小动态过程中有功功率的不平衡差额。通过调节角频率偏差补偿系数,在不改变原VSG有功控制稳态性能的同时,对系统动态性能的改善具有一致性,能同时满足有功和角频率最大超调量减小,系统响应时间和调整时间缩短的VSG控制器设计要求。最后通过Matlab/Simulink仿真算例验证了所提控制策略的有效性和优越性。

关键词(KeyWords)： 虚拟同步发电机;有功控制;虚拟惯量;虚拟阻尼;角频率偏差补偿;动态性能
