Phasor measurement units (PMUs) are important devices for protection, monitoring, and
control of modern power systems. Unlike the supervisory control and data acquisition
(SCADA) system which only measure the magnitude, PMUs can provide a set of
synchronized phasor measurements with high sampling rate with the accuracy of less than
one second, for better system monitoring especially during the outages. Since the PMUs are
costly devices, system operator is not able to install a PMU at each bus to maximize the
observability of system. To this end, determination of the number of PMUs in the system
for having a 100% observability is pivotal. In this paper, honey bee mating optimization
(HBMO) approach is utilized to allocate PMUs in modern power systems. Moreover, the
impact of line outages, as well as measurement loses, are considered. The simulation results
show the effectiveness of the proposed method on solving the PMU placement problem.
