This paper introduces the concept of adaptive coordination of damping controllers for enhancing power system stability. The coordination uses phasor measurement units (PMUs) to adapt to different disturbances by selecting the switching status (on/off

Online decision support for effective mitigation actions against propagating cascading outages in a power grid still poses a big challenge to grid operators. This paper proposes an online mitigation strategy against cascading outages using an optimal

Many steady-state power-flow-based models for cascading outage simulation have not considered frequency, which, however, is an important indicator of generation-load imbalance. This paper proposes a novel steady-state approach for simulating cascadin

Real-time damping estimation for a dominant inter-area mode is important for situational awareness of potential angular instability in power systems. Electromechanical oscillations energized by large disturbances often manifest obvious nonlinearities

This paper presents a new control method to enable large-scale solar photovoltaic (PV) plants to damp electromechanical oscillations. The proposed step-down modulation (SDM) control method is based on active power modulation, and it does not require

This article develops a practical framework of Area Angle Monitoring (AAM) to monitor in real time the stress of bulk power transfer across an area of a power transmission system. Area angle is calculated from synchrophasor measurements in real time

Harmonics in synchrophasor measurements of forced-oscillation events in the power grid are used to support localization of oscillation sources. A network-theoretic argument is presented which shows that harmonics at sufficiently high frequencies degr

This letter proposes a new approach for online detection of low-quality synchrophasor data under both normal and event conditions. The proposed approach utilizes the features of synchrophasor data in time and frequency domains to distinguish multiple

Traditional methods for validating generator models require taking generating units offline and performing staged tests. Techniques that are developed using synchrophasor data from Phasor Measurement Units (PMUs) allow validation of generator models
