“…Misclassification of metaheuristic techniques presented is correctly presented in our paper. Baba et al [21] reviewed a few published articles available in the literature about OPP for network observability. Johnson et al [22] reviewed different properties of OPP formulation and shortcomings of the techniques in OPP.…”

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

“…Although measurements are scanned through out the system, the system's state is presumed to be static.Whereas power systems are operated completely dynamic in nature. High price tags of PMUs forced the researchers to investigate the optimal locations for the complete observability of the electric network [20]- [27].…”

<span>Sustained growth in the demand with unprecedented investments in the transmission infrastructure resulted in narrow operational margins for power system operators across the globe. As a result, power networks are operating near to stability limits. This has demanded the electrical utilities to explore new avenues for control and protection of wide area systems. Present supervisory control and data acquisition/energy management systems (SCADA/EMS) can only facilitate steady state model of the network, whereas synchrophasor measurements with GPS time stamp from wide area can provide dynamic view of power grid that enables supervision, and protection of power network and allow the operator to take necessary control/remedial measures in the new regime of grid operations. Construction of phasor measurement unit (PMU) that provide synchrophasors for the assessment of system state is widely accepted as an essential component for the successful execution of wide area monitoring system (WAMS) applications. Commercial PMUs comes with many constraints such as cost, proprietary hardware designs and software. All these constraints have limited the deployment of PMUs at high voltage transmission systems alone. This paper addresses the issues by developing a cost-effective PMU with open-source hardware, which can be easily modified as per the requirements of the applications. The proposed device is tested with IEEE standards.</span>

“…This measurement is somehow bearable to monitor the power system in a stable condition; however, during the uncertainty and disturbance in the electrical network, this measurement level is not good enough to monitor the varying effects in the system. The lack of monitoring, controlling, and protecting performance in the previous devices was noticed, therefore a novel device was introduced with Global Positioning Systems (GPS) and digital signal processing (DSP) in the late 1980s in the research laboratory of the University of Virginia [3]. In the latest survey according to North America Synchrophasor Initiative (NASPI), there are nearly 2000 PMU devices installed in the North American transmission and distribution network [4].…”

“…The real-time synchronized measurement is obtained by the improvement in monitoring, protection, and control of the power system [3]. Similarly, PMU provides the real-time synchronized measurement, synchronized frequency, rate of change of frequency of voltage, current phasor quantities, and their magnitude with a high precision rate of ±1 • or ±1% [2][3][4][5][6][7][8] with the support of GPS [14,15]. The measurement level of PMUs is very high -nearly 60 samples of measurement per cycle as compared to the traditional devices [16].…”

The electrical network is a man-made complex network that makes it difficult to monitor and control the power system with traditional monitoring devices. Traditional devices have some limitations in real-time synchronization monitoring which leads to unwanted behavior and causes new challenges in the operation and control of the power systems. A Phasor measurement unit (PMU) is an advanced metering device that provides an accurate real-time and synchronized measurement of the voltage and current waveforms of the buses in which the PMU devices are directly connected in the grid station. The device is connected to the busbars of the power grid in the electrical distribution and transmission systems and provides time-synchronized measurement with the help of the Global Positioning System (GPS). However, the implementation and maintenance cost of the device is not bearable for the electrical utilities. Therefore, in recent work, many optimization approaches have been developed to overcome optimal placement of PMU problems to reduce the overall cost by providing complete electrical network observability with a minimal number of PMUs. This research paper reviews the importance of PMU for the modern electrical power system, the architecture of PMU, the differences between PMU, micro-PMU, SCADA, and smart grid (SG) relation with PMU, the sinusoidal waveform, and its phasor representation, and finally a list of PMU applications. The applications of PMU are widely involved in the operation of power systems ranging from power system control and monitor, distribution grid control, load shedding control and analyses, and state estimation which shows the importance of PMU for the modern world.
