Authors: MEHRDAD TARAFDAR HAGH, MEHDI AHMADI JIRDEHI

Abstract: This paper presents a Least Absolute Value (LAV) state estimator for power system using a new method called Recursive Least Squares (RLS). Also, a suitable model is used for state estimation of power system that includes a Unified Power Flow Controller (UPFC). The IEEE 14-bus test system is used to show the validity of the proposed algorithm in estimation of power system states as well as the states of controllable parameters of UPFC.

Keywords: RLS method, State estimation, UPFC, Power system states estimator
