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).

Manipulation of Static and Dynamic Data Center Power Responses to Support Grid Operations
IEEE Access, 2020 This research investigates three frameworks for data centers to deliver fast frequency response services from their UPS storage systems, HVAC cooling units, and the ability of off-gridding the entire data center during transient frequency events. The aim

Rapid Power Compensation-Based Frequency Response Strategy for Low-Inertia Power Systems
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2021 To reduce the frequency deviation and the rate of change of frequency (RoCoF) in a low-inertia power system, some converters are required to provide the frequency response (FR) power normally associated with the frequency deviation and/or the RoCoF, by ...

Synthetic inertia versus fast frequency response: a definition
IET Renewable Power Generation, 2017 This study discusses synthetic inertia from the perspective of a transmission system operator and compares it to fast frequency response based on frequency deviation. A clear distinction of the meanings between these concepts is discussed, the basis of which is a description of their characteristics.
