Systems and methods for power system state estimation using semidefinite relaxation (sdr)

Abstract

A system for power system state estimation can include one or more processors and a memory storing computer instructions, which when executed cause the system to a system can comprise one or more processor and a memory storing computer instructions. The computer instructions, when executed by the one or more processors, can cause the one or more processors to acquire, from remote terminal units, measurement data of a plurality of parameters of a power system, acquire network topology data of the power system, and determine estimates of a plurality of states of the power system using the measurement data, the network topology data and a semidefinite relaxation formulation. The semidefinite relaxation formulation can include a convex lower bound approximation of a rank function of an augmented state matrix.
