Abstract
Synchrophasor technology opens a new window for power system observability. Phasor measurement units (PMUs) are able to provide synchronized and accurate data such as frequency, voltage and current phasors, vibration, and temperature for power systems. Thus, the utilization of PMUs has become quite important in the fast monitoring, protection, and even the control of new and complicated distribution systems. However, data quality and communication are the main concerns for synchrophasor applications. This study presents a comprehensive survey on wide-area monitoring systems (WAMSs), PMUs, data quality, and communication requirements for the main applications of PMUs in a modern and smart distribution system with a variety of energy resources and loads. In addition, the main challenges for PMU applications as well as opportunities for the future use of this intelligent device in distribution systems will be presented in this paper.
Highlights
Worldwide, increasing pressure is being placed on the electric power grids and in particular distribution systems due to the steadily increasing introduction of renewable energy resources (RESs).For this reason, the European Commission has a long-term plan to increase the use of RESs
Besides the advantages of using Phasor measurement units (PMUs) in power systems, PMU applications are faced with many challenges in distribution systems, such as inadequate phasor measurement accuracy and a lack of communication network infrastructure that can support a large number of sensors and actuators with different technologies
Using a single comprehensive data/sensor architecture is an opportunity for distribution systems to access high-accuracy voltage and current phasors using PMUs
