A Critical Review of State-of-the-Art Optimal PMU Placement Techniques

Phasor measurement unit (PMU) technology is a need of the power system due to its better resolution than conventional estimation devices used for wide-area monitoring. PMUs can provide synchronized phasor and magnitude voltage current measurements state prevent blackouts. The drawbacks PMU are high cost device installation. main aspect using in electrical networks property observe adjacent buses, thereby making it possible with fewer number buses through their optimal placement. In last two decades, exhaustive research has been done on this issue. Considering importance field, comprehensive review progress achieved until now carried out limitations existing reviews literature highlighted. This paper be seen as major attempt an up-to-date work all-important field placement indicates that some perspectives still attention. Eventually, will open new standpoint community fill gap.
