Nilanjan Ray Chaudhuri is a leading expert in power system dynamics and control. His research addresses critical challenges in maintaining the reliability and resilience of modern electric power grids, including the impacts of rapid demand shifts from data centers, renewable integration, and phenomena leading to cascading blackouts and/or infrastructure damage. Through advanced lab facilities and simulation platforms, his team replicates real-world grid behavior to develop innovative solutions.
Chaudhuri’s work spans wide-area monitoring, power electronics applications, and advanced control strategies for technologies such as FACTS, HVDC, inverter-based resources, and distributed energy resources. By bridging academia, industry, and national labs, he helps utilities and regulators anticipate risks, improve simulation techniques, and establish standards that ensure grid security and sustainability in an increasingly complex energy landscape.
