Abstract
Virtual synchronous generator (VSG) controllers-based grid forming (GFM) converters have proven their capability in weak grids, however, their response in strong grids should be enhanced. Also, realizing DC-link control in these controllers is necessary in solar applications. These VSG controllers shall realize power synchronization loop of GFM converters for solar plants. This paper investigates the transient response of selected DC-link voltage controllers under different line impedances. It also proposes a modified virtual synchronous (mViSync) controller which is robust in both weak and strong grids. The transient response of the mViSync is then analyzed and compared to other controllers. Simulation results of the GFM converter based solar plant under altered conditions are performed. The results confirm the faster dynamic response and robustness of the proposed controller in both weak and strong grids.
