Smoothed Two-Stage Decomposition Algorithm for Solving Large-Scale Transmission and Distribution AC-OPF Problems
Juan Ospina, Manuel Garcia, Xinyi Luo +3
The integration of distributed energy resources (DERs) into the power grid has introduced new challenges to AC optimal power flow (AC-OPF) problems. Traditional OPF optimize consid…
Efficient Graph Partitioning under Resource Constraints: A Cutting-Plane Framework for Distribution Grids
Duong Thuy Anh Nguyen, Harsha Nagarajan, Robert Ferrando +2
This paper presents an optimal network topology control framework using cutting-plane methods for efficient network partitioning with controllable edges. The objective is to enable…
Reconfiguration and Real-Time Operation of Networked Microgrids Under Load Uncertainty
Hannah Moring, Bala Kameshwar Poolla, Harsha Nagarajan +3
Distribution networks are increasingly exposed to threats such as extreme weather, aging infrastructure, and cyber risks--resulting in more frequent contingencies and outages, a tr…
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…
