Assurance of Stability: Non-Intrusive Oscillation Monitoring and Early Warning (NOME)

In the Data-Driven Oscillation Monitoring and Early Warning (DOME) project with NESO, we have demonstrated that impedance participation factor (IPF) is an effective early-warning method for generic (including IBRs induced) oscillations. However, the IPF were obtained by frequency-screening of the system, which may pose a stability risk itself, due to the extra and sustained perturbation needed during the frequency-screening. This project will investigate non-intrusive perturbation methods based on DOME and thereby develop an early warning system for oscillations with minimum impact on system stability.  

Benefits

Expensive mitigation actions are typically taken after a major oscillation event. The cost of an oscillation event can be even higher if it triggers a power outage. This project enables NESO to rapidly and accurately identify the origins of oscillations and thereby limit the range and impact of oscillation events. The project additionally provides a tool for the NESO to communicate with vendors for effective cause identification and troubleshooting. The project aims to deliver clear guidelines for deploying data measurement devices
