Novel Utilization of Phasor Measurement Units (PMU) in Smart Grid Restoration: A Brief Survey

摘要

As the power grid is becoming smarter, the aspect of reliability is very important when an electric power network is subjected to disturbances at any instance of time and location. Restoring the power system to its normal operating condition post-disturbance is vital, to minimize the impact on its reliability needs. With the deployment of smart grid, an enhanced and intelligent restoration system is possible given the large-scale implementation of online monitoring systems and advanced technologies. Online monitoring systems (OMSs) and information and communication technologies (ICTs) provide situational awareness and intelligence of power system operation from a local and wide-area perspective. As the traditional power system becomes complex, the next-generation grid is commonly referred to as a smart grid. Applications of advanced tools and online monitoring systems become the need of the hour under such circumstances. The potentials and challenges associated in restoration process become vital as the grid becomes smarter. This paper presents a brief review and vision for the future in deploying PMUs for smart grid restoration.
