In the present paper, the effects of Phasor Measurement Unit (PMU) on Weighted Least Squares (WLS) State Estimation are investigated using a proposed approach whereas the network parameters are subjected to different amounts of uncertainty. The approach is implemented and tested on IEEE 14-Bus power network test case. The novelty of this investigation lies behind the consideration of network parameters...
This paper investigates how the efficiency of Weighted Least Squares (WLS) State Estimation changes according to both the uncertainty of network parameters and the uncertainty of measurements. Performance of State Estimator based mainly on the accuracy of its inputs and it is very important for the power system planners to improve the state estimation by determining whether to invest on increasing...
