Real-time Power System State Estimation and Forecasting via Deep Neural Networks
Liang Zhang, Gang Wang, Georgios B. Giannakis
Contemporary power grids are being challenged by rapid voltage fluctuations that are caused by large-scale deployment of renewable generation, electric vehicles, and demand respons…
Compressive Phase Retrieval via Reweighted Amplitude Flow
Liang Zhang, Gang Wang, Georgios B. Giannakis +1
The problem of reconstructing a sparse signal vector from magnitude-only measurements (a.k.a., compressive phase retrieval), emerges naturally in diverse applications, but it is NP…
Randomized Block Frank-Wolfe for Convergent Large-Scale Learning
Liang Zhang, Gang Wang, Daniel Romero +1
Owing to their low-complexity iterations, Frank-Wolfe (FW) solvers are well suited for various large-scale learning tasks. When block-separable constraints are present, randomized…
Scheduling of EV Battery Swapping, II: Distributed Solutions
Pengcheng You, Steven H. Low, Liang Zhang +4
In Part I of this paper we formulate an optimal scheduling problem for battery swapping that assigns to each electric vehicle (EV) a best station to swap its depleted battery based…
Sparse Phase Retrieval via Truncated Amplitude Flow
Gang Wang, Liang Zhang, Georgios B. Giannakis +2
This paper develops a novel algorithm, termed \emph{SPARse Truncated Amplitude flow} (SPARTA), to reconstruct a sparse signal from a small number of magnitude-only measurements. It…
Scalable Electric Vehicle Charging Protocols
Liang Zhang, Vassilis Kekatos, Georgios B. Giannakis
Although electric vehicles are considered a viable solution to reduce greenhouse gas emissions, their uncoordinated charging could have adverse effects on power system operation. N…
Voltage Regulation Algorithms for Multiphase Power Distribution Grids
Vassilis Kekatos, Liang Zhang, Georgios B. Giannakis +1
Time-varying renewable energy generation can result in serious under-/over-voltage conditions in future distribution grids. Augmenting conventional utility-owned voltage regulating…
Optimal Scheduling of Electric Vehicles Charging in low-Voltage Distribution Systems
Shaolun Xu, Liang Zhang, Zheng Yan +3
Uncoordinated charging of large-scale electric vehicles (EVs) will have a negative impact on the secure and economic operation of the power system, especially at the distribution l…
