PMU-based two stages state estimation for power system with nonlinear devices

This paper presents a two-stage state estimation method for power system containing multiple nonlinear devices. In this work two types of nonlinear devices are considered, phase-shifting transformers and unified power flow controllers. It is assumed that Phasor Measurement Units are available in ord...
