Robust Power System State Estimation for the Nonlinear AC Flow Model
Hao Zhu, Georgios B. Giannakis
An important monitoring task for power systems is accurate estimation of the system operation state. Under the nonlinear AC power flow model, the state estimation (SE) problem is i…
Precoder Design for Physical Layer Multicasting
Hao Zhu, Narayan Prasad, Sampath Rangarajan
This paper studies the instantaneous rate maximization and the weighted sum delay minimization problems over a K-user multicast channel, where multiple antennas are available at th…
Lassoing Line Outages in the Smart Power Grid
Hao Zhu, Georgios B. Giannakis
Fast and accurate unveiling of power line outages is of paramount importance not only for preventing faults that may lead to blackouts, but also for routine monitoring and control…
Sparsity-Cognizant Total Least-Squares for Perturbed Compressive Sampling
Hao Zhu, Geert Leus, Georgios B. Giannakis
Solving linear regression problems based on the total least-squares (TLS) criterion has well-documented merits in various applications, where perturbations appear both in the data…
