State estimation including synchronized measurements

The paper presents a methodology to include measurements from phasor measurement units (PMUs) as well as conventional measurements in a state estimator. A comprehensive strategy to combine conventional measurements, such as the power flow and power injection measurements, with the direct and pseudo-voltage measurements by the PMUs in a weighted least square (WLS) formulation of the state estimation problem is demonstrated. The proposed state estimator is applied on the IEEE 14-bus test system, and the simulation results are presented.
