一种基于小交流信号注入的孤岛微电网并联逆变器分散式二次电压控制及精确无功功率分配方法

To compensate for the voltage deviation at the point of common coupling (PCC) without communication links among distributed generations (DGs) in an islanded microgrid, proportional-integral regulator based secondary voltage control (PI-SVC) has been proposed in the literature. However, PI-SVC will degrade reactive power sharing performances, resulting from the activation time differences of second...
