The energy storage virtual synchronous generator (VSG), which can provide inertial support for the grid, has attracted wide attention. However, there is a problem that the dynamic characteristics and the characteristics of primary frequency modulation of grid-connected active power cannot be satisfied at the same time. Therefore, the dynamic oscillations suppression strategy of energy storage VSG ...Show More
The energy storage virtual synchronous generator (VSG) can provide certain inertia support for the renewable energy power generation system, but its virtual damping coefficient is coupled with the primary frequency modulation coefficient, so the dynamic oscillation and the steady-state error of its grid-tied active power cannot be eliminated simultaneously when the active power command and the gri...Show More
The phase difference between the grid voltage and current in grid-connected current source inverter is affected by the PI controller parameters, filter inductor and equivalent resistance. To eliminate the phase difference, three phase compensation strategies are proposed: phase compensation based on phase detection, phase compensation based on output power detection, and filter inductance regulati...Show More
