Copositive Characterizations of Convex Hull Pricing
Madhusudan Ghosh, Antoine Lesage-Landry, Joshua Adam Taylor
Due to the nonconvex binary constraints of unit commitment (UC), no uniform linear pricing scheme supports the optimal dispatch. Convex hull pricing (CHP) and copositive duality pr…
Optimal Active Fault Detection in Inverter-Based Grids
Mohammad Pirani, Mehdi Hosseinzadeh, Joshua A. Taylor +1
Ground faults in converter-based grids can be difficult to detect because, unlike in grids with synchronous machines, they often do not result in large currents. One recent strateg…
Optimally Scheduling Public Safety Power Shutoffs
Antoine Lesage-Landry, Félix Pellerin, Joshua A. Taylor +1
In an effort to reduce power system-caused wildfires, utilities carry out public safety power shutoffs (PSPS) in which portions of the grid are de-energized to mitigate the risk of…
Copositive Duality for Discrete Markets and Games
Cheng Guo, Merve Bodur, Joshua A. Taylor
Optimization problems with discrete decisions are nonconvex and thus lack strong duality, which limits the usefulness of tools such as shadow prices and the KKT conditions. It was…
Online Convex Optimization with Binary Constraints
Antoine Lesage-Landry, Joshua A. Taylor, Duncan S. Callaway
We consider online optimization with binary decision variables and convex loss functions. We design a new algorithm, binary online gradient descent (bOGD) and bound its expected dy…
Second-order Online Nonconvex Optimization
Antoine Lesage-Landry, Joshua A. Taylor, Iman Shames
We present the online Newton's method, a single-step second-order method for online nonconvex optimization. We analyze its performance and obtain a dynamic regret bound that is lin…
Attack Resilient Interconnected Second Order Systems: A Game-Theoretic Approach
Mohammad Pirani, Joshua A. Taylor, Bruno Sinopoli
This paper studies the resilience of second-order networked dynamical systems to strategic attacks. We discuss two widely used control laws, which have applications in power networ…
Predictive Online Convex Optimization
Antoine Lesage-Landry, Iman Shames, Joshua A. Taylor
We incorporate future information in the form of the estimated value of future gradients in online convex optimization. This is motivated by demand response in power systems, where…
Estimating the Frequency Coupling Matrix from Network Measurements
Antoine Lesage-Landry, Siyu Chen, Joshua A. Taylor
Power converters are present in increasing numbers in the electric power grid. They are a major source of harmonic currents and voltages, which can reduce power quality and trip pr…
Setpoint Tracking with Partially Observed Loads
Antoine Lesage-Landry, Joshua A. Taylor
We use online convex optimization (OCO) for setpoint tracking with uncertain, flexible loads. We consider full feedback from the loads, bandit feedback, and two intermediate types…
Coupling Load-Following Control with OPF
Mohammadhafez Bazrafshan, Nikolaos Gatsis, Ahmad Taha +1
In this paper, the optimal power flow (OPF) problem is augmented to account for the costs associated with the load-following control of a power network. Load-following control cost…
Power Systems Without Fuel
Joshua Adam Taylor, Sairaj V. Dhople, Duncan S. Callaway
The finiteness of fossil fuels implies that future electric power systems may predominantly source energy from fuel-free renewable resources like wind and solar. Evidently, these p…
Phase Balancing Using Energy Storage in Power Grids under Uncertainty
Sun Sun, Ben Liang, Min Dong +1
Phase balancing is essential to safe power system operation. We consider a substation connected to multiple phases, each with single-phase loads, generation, and energy storage. A…
Price and capacity competition in balancing markets with energy storage
Josh A. Taylor, Johanna L. Mathieu, Duncan S. Callaway +1
Energy storage can absorb variability from the rising number of wind and solar power producers. Storage is different from the conventional generators that have traditionally balanc…
