On-line voltage stability monitoring and control in smart grid — A survey

Abstract

Most of the work on voltage stability assessment of power systems has concentrated on offline studies. With advancement in Phasor Measurement Unit (PMU) technology, it is quite possible to assess voltage stability margin of real time systems in smart grid. This paper has addressed on different works going on in the area of voltage stability monitoring and control using PMU technology. The report in this paper has elaborated on different methodologies which have been proposed in literature for optimal placement of PMUs for control of voltage stability margin in smart grid. The paper sets new scope for promising researchers for the best utilization of PMUs in online voltage stability monitoring and control in smart grid architecture.

Voltage stability assessment using PMUs and STATCOM

“…The majority of studies on STATCOM's involvement in improving the voltage stability of offline systems have been taken into consideration. It appears that voltage stability of online systems can be monitored and managed with the development of phasor measurement units (PMUs) [24]. This study suggests employing phasor measurement units to monitor and regulate the voltage stability of online systems used with STATCOM.…”
