Under Frequency Load Shedding based on PMU Estimates of Frequency and ROCOF

, 2018
The paper describes a local under-frequency load shedding and load restoration scheme, that exploits frequency and Rate-of-Change-of-Frequency (ROCOF) measurements produced by Phasor Measurement Units (PMUs) as detectors of a large contingency. The paper

Parameters setting of virtual inertia control to mitigate the risk of fast local frequency drop in a renewable power transmission network

International Journal of Electrical Power & Energy Systems
The risk of fast local frequency drop in renewable-integrated power systems can cause the rate of frequency change (RoCoF) to exceed safe limits, thereby threatening frequency stability.

Characteristics and operational control strategies of grid‐forming long‐/short‐duration energy storage systems: A review

Energy Conversion and Economics, Volume 7, Issue 2, Page 127-148, April 2026.
Abstract Energy storage systems (ESSs) are increasingly critical for maintaining the stability and flexibility in power systems with rising renewable penetration. Grid‐forming (GFM) ESSs have emerged as a pivotal technology, capable of providing essential voltage and frequency support by establishing grid references in converter‐dominated systems. This

Two‐Step Clustering‐Based Equivalent Modeling of Large‐Scale Wind Farms for Enhanced Primary Frequency Regulation

Wind Energy, Volume 29, Issue 2, February 2026.
ABSTRACT The focus on wind power frequency regulation has largely been on individual wind farms, which presents challenges in meeting the coordinated operation needs of multiple stations within large‐scale installations. To address issues of model simplification and accuracy, we propose a large‐scale wind farm equivalent modeling method based on ...
