The share of wind power has strongly increased in electricity production, raising several issues concerning its integration to power grids. Unexpected dynamic phenomena, such as oscillatory events around 13 Hz have been recorded in the US by Oklahoma Gas & Electric (OG&E). Such interactions differ from traditional and well studied inter-area oscillations, and the ability to detect them is beyond the measurement capabilities of most of the existing measurement equipment and monitoring tools in Energy Management Systems (EMS) systems.This paper presents the development and implementation of algorithms for PMU-based real-time fast sub-synchronous oscillation detection, focusing on the aforementioned case.The paper focuses on the tool itself and its algorithms, briefly presents an approach carried out for testing and validating it. Experience from the use of the tool at OG&E is also described.

“…As such transient, stability issues have already been studied [3]. However, it is only recently that some Transmission System Operators (TSOs) have measured, with PMUs [4], sub-synchronous oscillatory events resulting from interactions between wind farms at frequencies around 13-15 Hz.…”

“…Earlier studies have found that energy storage can compensate for the stochastic nature of the variable energy sources by storing the excessive energy when generation exceeds predicted levels and providing it back to the grid when generation levels fall short. For instance, islanded power networks featuring high level of wind power penetration are subjected to undesired perturbation jeopardizing the power network stability [1]. Consequently, pumped storage plants are a proven solution for storing electricity at large scale and offering flexibility to the power management.…”
