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…
Load Block Modeling in Distribution Systems: Network Reconfiguration for Load Restoration
David M. Fobes, Harsha Nagarajan, Manuel Garcia +2
The distribution system restoration (DSR) problem has received considerable attention over the last decade or more. Solutions to the DSR problem identify the best set or sequence o…
A Hybrid Decomposition Approach for Stochastic Unit Commitment with Combined-Cycle Generators
Rosemary Barrass, Harsha Nagarajan, Mathieu Tanneau +2
The U.S. power grid is undergoing a paradigm shift as energy demand grows in scale and volatility. In response to this growing need, the U.S. has increased adoption of combined-cyc…
A Parametric, Second-Order Cone Representable Model of Fairness for Decision-Making Problems
Kaarthik Sundar, Deepjyoti Deka, Russell Bent
The article develops a parametric model of fairness called "-fairness" that can be represented using a single second-order cone constraint and incorporated into existi…
Exact and Heuristic Approaches for the Stochastic N-k Interdiction in Power Grids
Kaarthik Sundar, Andrew Mastin, Manuel Garcia +2
The article introduces the stochastic N-k interdiction problem for power grid operations and planning that aims to identify a subset of k components (out of N components) that maxi…
Joint Expansion Planning of Power and Water Distribution Networks
Sai Krishna Kanth Hari, Ahmed Zamzam, Byron Tasseff +2
This research explores the joint expansion planning of power and water distribution networks, which exhibit interdependence at various levels. We specifically focus on the dependen…
Fairly Extreme: Minimizing Outages Equitably
Kaarthik Sundar, Deepjyoti Deka, Russell Bent
This paper focuses on the problem of minimizing the outages due to extreme events on the power grid equitably among all customers of the grid. The paper presents two ways of incorp…
Chance-Constrained Unit Commitment with N-1 Security and Wind Uncertainty
Kaarthik Sundar, Harsha Nagarajan, Line Roald +3
As renewable wind energy penetration rates continue to increase, one of the major challenges facing grid operators is the question of how to control transmission grids in a reliabl…
Tightening McCormick Relaxations for Nonlinear Programs via Dynamic Multivariate Partitioning
Harsha Nagarajan, Mowen Lu, Emre Yamangil +1
In this work, we propose a two-stage approach to strengthen piecewise McCormick relaxations for mixed-integer nonlinear programs (MINLP) with multi-linear terms. In the first stage…
