Abstract :
The impact of reloading conventional state estimation with the addition of synchronized phasor measurements to implement a real time monitoring, supervision and control tool with better features including accuracy and convergence, is evaluated. The accuracy of various state estimation methods using a combination of available conventional and phasor measurements is compared. The most suitable state estimation method for the analyzed cases is determined. The results obtained for a practical case of the Colombian Transmission System are compared to support the obtained conclusions.
