The increasing complexity and management of power systems, growing demand and service-quality expectations — for example, system reliability, efficiency and security — in addition to environmental energy sustainability concerns, have triggered the evolution of smart grids. Utilities are implementing new technologies in power systems, including renewable energy resources, distributed generation, and the latest information and communications technologies.
Transmission & Distribution World's March issue examines how Hydro-Quebec has adopted advanced distribution automation applications and power-quality monitoring in its smart grid.
Advanced distribution automation may be defined as a number of technologies that enable an electric utility to remotely monitor, coordinate and operate distribution components in a real-time mode from remote locations. The group of ADA technologies includes supervisory control and data acquisition (SCADA), volt and VAR control (VVC), fault location and feeder reconfiguration, or self-healing. In combination, this is known as fault location, isolation and service restoration (FLISR).
The article looks at each technology, and how the utitlity developed, implemented and is using each to work together.
