Robust Partitioning and Operation for Maximal Uncertain-Load Delivery in Distribution Grids
Hannah Moring, Harsha Nagarajan, Kshitij Girigoudar +2
To mitigate the vulnerability of distribution grids to severe weather events, some electric utilities use preemptive de-energization as the primary line of defense, causing signifi…
Identifying Secure Operating Ranges for DER Control using Bilevel Optimization
Kshitij Girigoudar, Line A. Roald
Active distribution grids are accommodating an increasing number of controllable electric loads and distributed energy resources (DERs). A majority of these DERs are managed by ent…
Chance-Constrained AC Optimal Power Flow for Unbalanced Distribution Grids
Kshitij Girigoudar, Ashley M. Hou, Line A. Roald
The growing penetration of distributed energy resources (DERs) is leading to continually changing operating conditions, which need to be managed efficiently by distribution grid op…
On the Impact of Different Voltage Unbalance Metrics in Distribution System Optimization
Kshitij Girigoudar, Line A. Roald
With increasing penetrations of single-phase, rooftop solar PV installations, the relative variations in per-phase loading and associated voltage unbalance are expected to increase…
