面向极弱电网下并网变流器鲁棒控制的电流导向锁相环方法

This letter presents a new phase-locked loop (PLL) control method for enhancing the synchronization stability of grid-following voltage-source converters in very weak grid conditions. This can be conveniently implemented without additional efforts on hardware and retains the existing PLL structure and current controller parameters. The proposed PLL method is competitive and effective for stability...
