VSG-Based Parameter Adaptive Control Strategy

VSG-Based Parameter Adaptive Control Strategy

As a large number of converters composed of power electronic devices are connected to the grid, power system has gradually decreased stability. How to increase dynamic response of the converter has become one of the research hotspots. Virtual synchronous generator technology (VSG) can endow the conv...
