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…
