Online Sketched Newton-Raphson
Jean-Luc Lupien, Yuen-Man Pun, Youssef Diouane +2
In online convex optimization (OCO), a decision-maker is confronted with an unknown environment and seeks to play an optimal sequence of decisions on a short time-scale using only…
Electric Grid Topology and Admittance Estimation using Phasor Measurements
Norak Rin, Iman Shames, Ian Petersen +1
Recent advances in precise phasor measurement units are enabling new approaches to estimate distribution and transmission grid parameters in real-time. In this paper, we investigat…
A Fundamental Convergence Rate Bound for Gradient Based Online Optimization Algorithms with Exact Tracking
Alex Xinting Wu, Ian R. Petersen, Iman Shames
In this paper, we consider algorithms with integral action for solving online optimization problems characterized by quadratic cost functions with a time-varying optimal point desc…
Electric Grid Topology and Admittance Estimation: Quantifying Phasor-based Measurement Requirements
Norak Rin, Iman Shames, Ian R. Petersen +1
In this paper, we quantify voltage and current phasor-based measurement requirements for the unique estimation of the electric grid topology and admittance parameters. Our approach…
