It is well known that Phasor Measurements Units (PMU) can improve the accuracy and efficiency of stateestimation. The mixed use of PMU and conventional measurements might be the most economic way to improve state estimation. However, the fact that PMU measurements and conventional measurements are indifferent coordinates makes them difficult to be combined in a same states estimator.
Smart Electric Grid, LLC provides a software package that is able to perform the following functions regarding PMU measurements:
1. Using linear integer programming to strategically provide an economic placement plan for synchronized Phasor measurements with/without the presence of conventional measurements.
2. Provides an efficient and fast state estimation solution for the combination of synchronized Phasor measurements and conventional measurements.
3. The SEG state estimator will be upgraded to include the synchronized Phasor measurements.
