Traditional distribution architectures are radial, open loop, and are operated with normally open points along the feeders o Distribution systems tend to be operated radially from a single substation

3.5 MVA

.5 MVA

o The picture on the right illustrates a common topology o At the bottom is a tie switch which is open during normal operations.

Overloaded Elements

o The concern is that if this tie switch were closed, there may be unanticipated loop flows.

Critical Load

The power flow controller can tie these feeds together into a meshed network increasing reliability, efficiency, and management of distributed generation 2.0 MVA

o By coupling these feeders with the power flow controller, loads can be balanced better through the substation transformers

2.0 MVA

o Reactive power can be supplied for Volt-Var Optimization o More reliable power can be supplied to critical loads P,Q

o Loop flows are eliminated by the device’s power flow control

Tie Controller can connect out of phase or differing magnitude voltage feeds and control real and reactive power flow, designed to support an entire 15kV 10MVA circuit Voltage Angle Mismatch Power Flow Controller:

Ability to couple together asynchronous connections, those with disparate phase angles

Voltage Magnitude Mismatch Power Flow Controller: Can couple together systems at different voltage levels
