A practical secondary frequency control (SFC) strategy for virtual synchronous generator (VSG) with predictable rotor frequency response is proposed in this letter. The relationship between rotor inertia, damping factor, integral coefficient and the time constant of low-pass filter is revealed, moreover, the complexity of parameter design is reduced obviously. Finally, the proposed concept is verified by Simulation results.
