Smart Grid Applications Distribution Management System (DMS) • A Decision Support System to assist the control room and field operating personnel with the monitoring and control of the electric distribution system
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. Transformers
TapChangers
Substation The amount of energy savings is contingent upon the voltage profiles for all feeders, load composition, time of day, and many other factors
V
CBs
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.
Upper limit 125V at Service Entrance 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.
Energy Savings
Critical point There is some voltage uncertainty, minimized by metering at select service entrances.
Lower limit 112V at Service Entrance
In Summary
The modernization of the power deliver system is necessary and imminent, providing an extraordinary challenge and opportunity for the utility industry… We need to work together on the many technical and business issues to succeed in delivering the system of the future!
