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…
Effective Capacity of a Battery Energy Storage System Captive to a Wind Farm
Vinay A. Vaishampayan, Thilaharani Antony, Amirthagunaraj Yogarathnam
Wind energy's role in the global electric grid is set to expand significantly. New York State alone anticipates offshore wind farms (WFs) contributing 9GW by 2035. Integration of e…
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…
A Case Study on Modeling Adequacy of a Grid with Subsynchronous Oscillations Involving IBRs
Lilan Karunaratne, Nilanjan Ray Chaudhuri, Amirthagunaraj Yogarathnam +1
A case study on modeling adequacy of a grid in presence of renewable resources based on grid-forming converters (GFCs) is the subject matter of this paper. For this purpose, a 4-ma…
An Approach to Evaluate Modeling Adequacy for Small-Signal Stability Analysis of IBR-related SSOs in Multimachine Systems
Lilan Karunaratne, Nilanjan Ray Chaudhuri, Amirthagunaraj Yogarathnam +1
Time-varying phasor-based analysis of subsynchronous oscillations (SSOs) involving grid-following converters (GFLCs) and its benchmarking with electromagnetic transient (EMT) model…
