Abstract The power grid is under pressure to operate closer to its security limits, as intermittent renewable energy gradually increasing. This paper describes the mathematical models of large-scale photovoltaic inverters that similates synchronous machines (VSG), such as inertia, damping, frequency and voltage controls, analyses its active power-frequency control, reactive power and voltage control stratigies, and discusses its cons-and-pros in integrating the large scale photovoltaic power plant into the power grid, and its prospects in the green low-carbon development era.

Key words： VSG photovoltaic-storage hybrid system connecting the grid clean energy
