Diffusion Model-based Parameter Estimation in Dynamic Power Systems

Feiqin Zhu, Dmitrii Torbunov, Zhongjing Jiang +4

Parameter estimation, which represents a classical inverse problem, is often ill-posed as different parameter combinations can yield identical outputs. This non-uniqueness presents…

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…
