Abstract :
To run a state estimator, modern control centers make use of both phasor measurement units (PMU) and conventional measurements. It is expected that in the near future, this hybrid set of measurements would be the common strategy to carry out the state estimation. This paper presents results that allow the assessment of the estimates´ precision when a variety of measurements are taken into account. Tests are evaluated on a grid of the open publications utilizing different sets of information.
