Discovery and Characterization of Cross-Area and Intra-Area SSOs Sensitive to Delay in Droop Control of Grid-Forming Converters
Lilan Karunaratne, Nilanjan Ray Chaudhuri, Amirthagunaraj Yogarathnam +1
Subsynchronous oscillations (SSOs) involving grid-forming converters (GFCs) are in a less familiar territory of power system dynamics. This letter reports a new phenomenon namely c…
An Approach for Fast Cascading Failure Simulation in Dynamic Models of Power Systems
Sina Gharebaghi, Nilanjan Ray Chaudhuri, Ting He +1
The ground truth for cascading failure in power system can only be obtained through a detailed dynamic model involving nonlinear differential and algebraic equations whose solution…
Preventing Outages under Coordinated Cyber-Physical Attack with Secured PMUs
Yudi Huang, Ting He, Nilanjan Ray Chaudhuri +1
Due to the potentially severe consequences of coordinated cyber-physical attacks (CCPA), the design of defenses has gained significant attention. A popular approach is to eliminate…
Dissipation of Oscillation Energy and Distribution of Damping Power in a Multimachine Power System: A Small-signal Analysis
Kaustav Chatterjee, Nilanjan Ray Chaudhuri
This paper revisits the concept of damping torque in a multimachine power system and its relation to the dissipation of oscillation energy in synchronous machine windings. As a mul…
Topology Estimation Following Islanding and its Impact on Preventive Control of Cascading Failure
Sai Gopal Vennelaganti, Nilanjan Ray Chaudhuri, Ting He +1
Knowledge of power grid's topology during cascading failure is an essential element of centralized blackout prevention control, given that multiple islands are typically formed, as…
Verifiable Failure Localization in Smart Grid under Cyber-Physical Attacks
Yudi Huang, Ting He, Nilanjan Ray Chaudhuri +1
Cyber-physical attacks impose a significant threat to the smart grid, as the cyber attack makes it difficult to identify the actual damage caused by the physical attack. To defend…
