Distribution Automation (DA) is viewed as an integral component of the Smart Grid paradigm. It facilitates the employment of computer technology and communication infrastructure to advance management and operation of the distribution network from a semi-automated approach towards a fully automated one. SCADA systems, advanced sensors, and electronic controllers are integrated into the DA system in...
Southern California Edison is developing a Smart Grid Demonstration project in Irvine California under ARRA funding from the DOE. The project, named the Irvine Smart Grid Demonstration (ISGD) is an integrated deployment of smart grid elements from transmission to the home. Subprojects of the ISGD include (1) Zero Net Energy Homes (ZNE), (2) a Solar Shade EV charging station, (3) Distribution Circuit...
VVC facilities that maintain acceptable voltage at all points along the distribution feeder and maintain high power factor have been a fundamental requirement for all electric distribution feeders. Recent Smart Grid initiatives have created growing interest in the deployment of more advanced Volt-VAR systems for efficiency improvement, demand reduction, and better overall asset utilization. This paper...
This paper summarizes the history of Distribution Automation (DA) at Progress Energy Carolinas (PEC). PEC's first introduction into DA occurred in 1997 with the installation of a DSCADA and Feeder Monitoring System. In addition to these systems, PEC also implemented a capacitor control program for distribution feeder capacitor banks. Currently PEC is implementing a Distribution System Demand Response...
This paper focuses on Load Tap Changer (LTC) transformer duties associated with SMART GRID (SG) Integrated Volt/Var/kW Management (IVVM) functions. Implementation of SG technology, with resultant changes in power systems, may cause increased or excessive tapchanger duties. These duties will be affected by a) the integration of renewable energy sources; b) more precise operational voltage control levels...
