| Abstract: | With the increased penetration of distributed generation, the power grid will gradually develop into a converter-dominant network with low inertia and under-damped, which leads to stability problems becoming more and more serious. Virtual synchronous generator (VSG) control technologies can mimic the mechanism of synchronous generator to improve the system stability, which earns it more concern and wide application. Firstly, the architecture and principles of the virtual synchronous generator control system are described, and then some key issues about VSG modeling, operation control, stability analysis and typical application are deeply reviewed. Many potential research hot points and solutions about VSG are also proposed.
