Brief Study on Applications of Phasor Measurement Units in Smartgrid Technology

Abstract

In this review paper mostly discusses Smart grid technologies nowadays' phasor measurement units (PMUs) uses and its role in the modern power grid increases. Uses of the PMUs in a smart grid have several applications in the wide-area monitoring system to protect the power flow from long transmitting system in real-time-monitoring. In this filed, application of synchrophasor act as bidirectional functions, such as both controlling and communication technology, recognize in a specific time horizon by using GPS. Since the PMUs can handle both monitoring and communication technology from generating station to end-users and vice versa. Such devices are costly since it is practically impossible to mount PMUs on each bus, and it is preferred to use in critical buses of the network. This paper explains the advantages of PMUs inclusion in the power system network. It addresses different optimum positioning methodology used to assess the required number of PMUs to achieve maximum observability of the modern power grid and give an idea about the future scope.
