Distribution networks, which are already complex large scale systems with diverse loads, are becoming more complicated in the smart grid era due to the increasing connections of distributed generators (e.g., solar and wind) and smart devices (e.g., electric vehicles and storage batteries). Although highly automated and integrated control systems have been proposed, systems with coverage from the zone...
While plug-in electric vehicles (PEVs) are expected to provide economic and environmental benefits to the transportation sector, they may also help the electric grid, both as a potential source of energy storage and as a means to improve power quality and reliability. In this paper, our focus is on the latter, where PEVs offer reactive power compensation using P-Q control at their charger inverters...
Dominion Virginia Power's Conservation Voltage Reduction program has demonstrated energy savings of up to 4% by optimizing off-peak voltage. The key innovation is incorporating end-of-line voltage data from every customer meter, which eliminates the need to maintain an electrical model of the feeder. CVR is accomplished via DMS control of the load tap changer based on voltage feedback from AMI meter...
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...
This paper summarizes the history of volt/VAR control at Progress Energy Carolinas (PES) for the transmission to distribution and distribution systems. PEC has transitioned from a volt/VAR control system that incorporated local control of capacitors and regulators to an automated system that provides remote control of feeder capacitor banks. Currently PEC is implementing a Distribution System Demand...
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...
