Exploring Rate of Change of Frequency (RoCoF) Events in the Nordic Synchronous Area from 2015 to 2023 [PDF]
As the world moves towards a sustainable and emission-free future, the power grid emerges as a key participant in providing electrical energy. With the demand for electrical energy rising, the power grid is challenged with larger loads. These higher loads, combined with more penetration of the lower inertia power sources, wind and solar, challenge the ...

Avoiding the non-detection zone of passive loss-of-mains (islanding) relays for synchronous generation by using low bandwidth control loops and controlled reactive power mismatches [PDF]
, 2014 Generation connected to electrical distribution systems requires reliable and timely detection of loss of-mains (islanding). Passive loss of mains detection relays typically use measurements of parameters such as frequency, phase, and the magnitudes of ...

Local Frequency-Based Estimation of the Rate of Change of Frequency of the Center of Inertia [PDF]
, 2020 This letter proposes a novel technique for estimating the rate of change of frequency (RoCoF) of the center of inertia (CoI) in power systems. To offer a holistic picture of the system's frequency response, the proposed technique requires local frequency

A New Passive Islanding Detection Solution Based on Accumulated Phase Angle Drift
Applied Sciences, 2018 The existing passive methods for islanding detection are mainly based on the detection of voltage and frequency deviation after islanding, using protections such as voltage vector shift (VVS) and rate of change of frequency (ROCOF).
