Supervisory Control and Data Acquisition (SCADA) systems that have been in use for the past four decades are rapidly being augmented by the phasor measurement units (PMU). PMUs are deployed for various applications and provide voltage and current phasor measurements that are time synchronized with respect to the GPS system clock and at much higher scan rates than those of SCADA measurements. Use of only phasor measurements simplifies the estimation formulation which in turn also facilitates implementation of some alternative robust estimation methods which have so far not been widely considered due to their computational disadvantages when applied to SCADA measurements. Use of phasor measurements also enables utilization of modal domain solutions paving the way to simple extension of estimation procedures to unbalanced multi-phase power grid monitoring. Numerical examples will be used to illustrate the discussed procedures and solutions when applied to typical power systems.
