State estimation accuracy enhancement for optimal power system steady state modes

Abstract

State estimation is an important tool for system operators, which determine the state of the system and accordingly act for control and operate the system. Ill conditioned system is a problem facing the state estimation algorithms, which results in numerical instability and inaccurate results of power system state estimation. This paper proposes a method to overcoming the ill-conditioned problem based on their linear correlations between the output parameters for obtaining optimal power systems steady state mode.

“…This reduces the power system losses and improves the voltage profile. In addition, the optimal implementation of FACTS controllers in the power system networks increases the capacity of networks without the expensive construction of new transmission systems [2][3][4]. FACTS devices are based on high-speed power electronics components that are connected to the electrical networks to increase controllability and maximize the capacity of the transferred power with a fast time response taking into consideration the power system constraints [5,6].…”
