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

Benefits of an Integrated Smart Grid Solution
CIGRE / FirstEnergy DOE Experience, Grid of the Future 23
■ Provides line of sight for grid operators all the way down to
the consumer endpoint
– DA & IVVC devices can be coordinated to optimize results
– AMI meters provide service level voltage
– IVVC can help synchronize voltages
■ Adds flexibility to accommodate distributed generation,
storage potential and other advanced distribution
technologies

■ Traditional circuit design brought power from a generating source
to the substation and then to end use customers
Reclosers R1, R3, R6, R7
Breakers A1, A2, B1, B2
Circuit Ties for DA
October 23, 2017CIGRE / FirstEnergy DOE Experience, Grid of the Future
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
October 23, 2017CIGRE / FirstEnergy DOE Experience, Grid of the Future
Circuit Ties w/
Manual Switches
Still Requires a
Truck Roll
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

Reclosers
■ Reclosers divide up the distribution circuit into small sections
■ Customer Benefits: improved restoration times and fewer
outages by isolating faults to smaller groups of customers

occurs between
A2 and R3; R3
