An Improved Control Method for Current-controlled VSG during Transient Voltage Disturbance

The control strategy of virtual synchronous generator (VSG) applied to the grid connection of inverter-interfaced distributed generation (IIDG) seriously degrades the output power quality during transient voltage disturbance, which endangers the safe and stable operation of power system. To solve this problem, an improved control strategy based on current-controlled VSG is proposed to continue to ...
