Phasor Measurement Unit

Phasor Measurement Units (PMUs) provide high-speed, synchronized measurements of voltage and current in power systems, enabling real-time monitoring and improved grid management. Current research focuses on leveraging PMU data with machine learning, particularly deep neural networks (DNNs) and graph neural networks (GNNs), for tasks such as state estimation, event classification, and anomaly detection. These advancements aim to enhance power system reliability, security, and efficiency by improving situational awareness and enabling faster, more accurate responses to disturbances and cyberattacks. The development of robust and scalable algorithms, along with addressing challenges like data scarcity and adversarial attacks, remains a key focus.
