Smart Grid Applications

Volt VAR Optimization (VVO)• A voltage control system at the substation medium voltage bus

that will allow the real time management of energy flows for loss reduction.

With VVO, load tap changers, capacitor banks and voltage regulators are continuously fine tuned throughout the year. The net effect is a flattening of voltage drop and lowering voltages at non-critical points resulting in substantial energy savings.

Feeder will experience voltage drop, depending on conductor size, load, and distance.Peak load (solid line) has more voltage drop than light load (dashed line).

Load tap changer at the substation can lower the voltage during light load, yet remain within operating limits at the service entrance.

The amount of energy savings is contingent upon the voltage profiles for all feeders, load composition, time of day, and many other factors

There is some voltage uncertainty, minimized by metering at select service entrances.
