Optimal partitioning in distributed state estimation considering a modified convergence criterion
Sajjad Asefi, Elena Gryazina, Helder Leite
Distributed state estimation (DSE) is considered as a more robust and reliable alternative for centralized state estimation (CSE) in power system. Especially, taking into account t…
Voltage Feasibility Boundaries for Power System Security Assessment
Mazhar Ali, Elena Gryazina, Anatoly Dymarsky +1
Modern power systems face a grand challenge in grid management due to increased electricity demand, imminent disturbances, and uncertainties associated with renewable generation, w…
Distributed state estimation: a novel stopping criterion
Sajjad Asefi, Sergei Parsegov, Elena Gryazina
Power System State Estimation (PSSE) has been a research area of interest for power engineers for a long period of time. Due to the intermittent nature of renewable energy sources,…
ADMM-based Distributed State Estimation for Power Systems: Evaluation of Performance
Samal Kubentayeva, Elena Gryazina, Sergei Parsegov +2
Recently, distributed algorithms for power system state estimation have attracted significant attention. Along with such advantages as decomposition, parallelization of the origina…
Geometry of quadratic maps via convex relaxation
Anatoly Dymarsky, Elena Gryazina, Sergei Volodin +1
We consider several basic questions pertaining to the geometry of image of a general quadratic map. In general the image of a quadratic map is non-convex, although there are severa…
