Tractable Identification of Electric Distribution Networks

no code implementations4 Apr 2023 Ognjen Stanojev, Lucien Werner, Steven Low, Gabriela Hug

In the first method, we use the eigendecomposition of the admittance matrix to generalize the notion of stationarity to electrical signals and demonstrate how the stationarity property can be used to facilitate a maximum a posteriori estimation procedure.

Learning Optimal Power Flow: Worst-Case Guarantees for Neural Networks

no code implementations19 Jun 2020 Andreas Venzke, Guannan Qu, Steven Low, Spyros Chatzivasileiadis

This paper introduces for the first time a framework to obtain provable worst-case guarantees for neural network performance, using learning for optimal power flow (OPF) problems as a guiding example.

Inverse Power Flow Problem

no code implementations21 Oct 2016 Ye Yuan, Steven Low, Omid Ardakanian, Claire Tomlin

We show that the admittance matrix can be uniquely identified from a sequence of measurements corresponding to different steady states when every node in the system is equipped with a measurement device, and a Kron-reduced admittance matrix can be determined even if some nodes in the system are not monitored (hidden nodes).
