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…
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…
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…
Solving Three-phase AC Infeasibility Analysis to Near-zero Optimality Gap
Bikram Panthee, Amritanshu Pandey
Recent works have shown the use of equivalent circuit-based infeasibility analysis to identify weak locations in distribution power grids. For three-phase power flow problems, when…
PowerChain: A Verifiable Agentic AI System for Automating Distribution Grid Analyses
Emmanuel O. Badmus, Peng Sang, Dimitrios Stamoulis +1
Rapid electrification and decarbonization are increasing the complexity of distribution grid (DG) operation and planning, necessitating advanced computational analyses to ensure re…
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…
