With the development of distributed energy and clean energy

power electronics technology has gradually become the focus of power grid research

and virtual synchronous generator（VSG） has greatly improved the low inertia and underdamage of power grid electronics. This paper first introduces the basic principle of virtual synchronous generator

compare basic control strategies

then summarizes the application prospect of virtual synchronous generator in wind power

photovoltaic

flexible DC transmission in detail

and Finally

combining with the current power grid

the key technologies of the future development of virtual synchronous generator technology are discussed.
