Abstract

State estimation is a computer program that helps to process the raw measurements and determine the power system state. Paper provides the commonly used state estimation method. It outlines Weighted Least Square Technique and the steps involved in the estimation. The paper describes application of the method based on IEEE 14 bus system and IEEE 30 bus system. It is predetermined system model and carried out in order to provide best estimate of what is happening in the system based on real time measurements data. The simulation program is run on the MATLAB (2013) platform.
