AC Dynamics-aware Trajectory Optimization with Binary Enforcement for Adaptive UFLS Design
Muhammad Hamza Ali, Amritanshu Pandey
The high penetration of distributed energy resources, resulting in backfeed of power at the transmission and distribution interface, is causing conventional underfrequency load she…
Grid-ECO: Grid Aware Electric Vehicle Charging Stations Placement Optimizer
Bikram Panthee, Haoming Yang, Corey D. Harper +1
The paper develops a methodology, Grid-ECO, to optimally allocate electric vehicle charging stations (EVCS) within a distribution feeder, while considering EV charging demand at ce…
Two-Stage Bidirectional Inverter Equivalent Circuit Model for Distribution Grid Steady-State Analysis and Optimization
Emmanuel O. Badmus, Amritanshu Pandey
This paper presents a \textit{physics-based} steady-state equivalent circuit model of a two-stage bidirectional inverter. These inverters connect distributed energy resources (DERs…
Stochastic framework for scheduling preemptive upgrades of distribution transformers
William A Wheeler, Samuel Chevalier, Amritanshu Pandey
Electrification of residential heating and transporta- tion has the potential to overload transformers in distribution feeders. Strategic scheduling of transformer upgrades to anti…
