Policy Gradient-Based EMT-in-the-Loop Learning to Mitigate Sub-Synchronous Control Interactions
Sayak Mukherjee, Ramij R. Hossain, Kaustav Chatterjee +2
This paper explores the development of learning-based tunable control gains using EMT-in-the-loop simulation framework (e.g., PSCAD interfaced with Python-based learning modules) t…
Oscillation Analysis and Damping Control for a Proposed North American AC-DC Macrogrid
Kaustav Chatterjee, Sameer Nekkalapu, Antos Varghese +3
In recent years, several studies conducted by both industry and U.S. Department of Energy (DOE)-funded initiatives have proposed linking North America's Eastern and Western Interco…
Identification of Sub/Super-Synchronous Control Interaction Paths Using Dissipative Energy Flow
Kaustav Chatterjee, Sameer Nekkalapu, Sayak Mukherjee +2
Sub- and super-synchronous control interactions (SSCIs) are oscillations arising from adverse interactions between inverter-based resource (IBR) controls and the power network. SSC…
Development of Reduced Feeder and Load Models Using Practical Topological and Loading Data
Sameer Nekkalapu, Sushrut Thakar, Antos Cheeramban Varghese +3
Distribution feeder and load model reduction methods are essential for maintaining a good tradeoff between accurate representation of grid behavior and reduced computational comple…
