RoCoF Droop Control of PMSG-Based Wind Turbines for System Inertia Response Rapidly
IEEE Access, 2020 This paper proposes a RoCoF droop control, which relieves the transient frequency change process by controlling the energy of the DC side capacitor. Firstly, analyze and classify the control time scale of the wind power system (WPS).

Improved Droop Control with Washout Filter [PDF]
Energies, 2018 In this paper, a droop washout filter controller (DWC), composed of a conventional droop controller and a washout filter controller, is proposed. The droop controller is used to ensure the “plug-and-play” capability, and the droop gain is set small. The washout filter is introduced to compensate the active power dynamic performance (APDP).
