Voltage Control Jan 2013 – Transmission/Generations Buses with a Defined Voltage Profile - Boxes represent the 25%/75% percentiles. Leader lines show the min/max voltage during the period. - Data is normalized so that the 1.0 per-unit value represents the control point from the voltage profile. - Based on one-minute PI data Preliminary Information for Reliability Discussion
