Sensitivity-Based System Strength Assessment: Mapping Power Flow and Network Topology Perturbations to System Eigenvalues
Trager Joswig-Jones, Shuan Dong, Jin Tan +1
As inverter-based resources (IBRs) contribute larger shares of generation in electrical power grids, quantifying system strength becomes increasingly important for identifying stab…
Switching-Reference Voltage Control for Distribution Systems with AI-Training Data Centers
Mingyuan Yan, Trager Joswig-Jones, Baosen Zhang +2
Large-scale AI training workloads in data centers exhibit rapid and periodic power swings that can induce voltage deviations in power distribution systems. Existing voltage control…
Convexity and Optimal Online Control of Grid-Interfacing Converters with Current Limits
Lauren Streitmatter, Trager Joswig-Jones, Baosen Zhang
Converter-based generators and loads are growing in prevalence on power grids across the globe. The rise of these resources necessitates controllers that handle the power electroni…
Safe Trajectory Gradient Flow Control of a Grid-Interfacing Inverter
Trager Joswig-Jones, Baosen Zhang
Grid-interfacing inverters serve as the interface between renewable energy resources and the electric power grid, offering fast, programmable control capabilities. However, their o…
Geometry of the Feasible Output Regions of Grid-Interfacing Inverters with Current Limits
