This paper presents a study of the effect of measurement's weight and error on the accuracy of WLS power system state estimation and the correlation between those two parameters and measurement's type. Different simulation cases are tested on a real Network of 14 bus , part of the electrical transmission network of the Moroccan National Office for Electricity and Potable Water (ONEE).
