Smart Grid (Energy Transmission & Distribution)

Smart Grid is a transformed electricity transmission and distribution network or "grid" that uses robust two-way communications, advanced sensors/meters, and distributed computers to improve the efficiency, reliability and safety of power delivery and use. Think of a Smart Grid as an “internet routing network” for Electricity, instead of for Data.

The Smart Grid is enabled by the convergence of technologies from several industries

High Temperature Superconductivity (HTS) Cables Yttrium Barium Copper Oxide (YBCO) YBa2Cu3O7

5/8/2011 28 Prepared by Dr. William Kao

Resistance of YBCO

This superconductor operated at 93 K, notable because this is above liquid nitrogen's boiling point (77.1 K). 92 Kelvin = -181.15 Celsius

Summary and Conclusion

• Smart Grid: definition, components.
• Three key elements: Architecture, Communications,

Technology

• Five technology areas in SM : Sensing & Meas.,

Advanced Control Methods, Improved Interface & Decision Support, Advanced Components, and Integrated Communications.

• Focus on advances in:
• Hardware (meters, sensors,..)
• Software (HEMS,…)
• Components (cables, storage,…)
• Smart Grid will evolve over next 5-15 years, most of

the work still lays ahead of us!
