FE Integrated Volt/Var Control
Reliability focused
• Maximize Power Quality - Optimize voltage
levels, flatten voltage, prevent voltage sags
• Reactive Support - Provide reactive support to
the transmission system
• Respect Voltage Limits - 106% to 98% of
nominal, minimizes device operation
Energy efficiency / cost savings focused
• Loss Minimization - Flatten voltage, reduce
losses - both kW & kVAR
• Minimize Demand - Reduce kW while still
providing acceptable voltage

Circuit Ties (continued)
■ Customer Benefits: allow customers to be served from multiple
sources; facilitates modern grid architecture
28
Example: Fault
occurs between A2
and R3; Customers on
remainder of circuit
can be restored by a
manually closing a
normally open switch
shortening the duration
of their outage

Reconductoring for DA
■ When creating new circuit ties, wire size needs to be increased
to accommodate new power flows on the lines
■ Customer Benefits: facilitates power flows from multiple sources;
improves the resiliency of the line making it better able to
withstand adverse weather conditions
