Smart Grid ???

U.S. Department of Energy:

A smart grid integrates advanced sensing

technologies, control methods, and integrated

communications into the current electricity grid


3/19

Old Electrical Infrastructure (Power Grid)

Current Power Grid

It is not efficient Transmission Loss: Up to 20%

Distribution Loss: Up to 30%

It has not kept pace with modern challenges

Generation must follow demand to ensure balanced grid

No dynamic pricing

Limited or hard to intergrated alternative power generation sources

Poor situation awareness, damage isolation...

Poor control and management of distribution network. No control to help

change behavior

Energy Management: is it important?

Daily Load Distribution Washing Machine (%)

Washing machine, dryer and dish

washer represent >10% of household

electricity consumption

All three run mainly during peak

hours

Intelligent energy management and

home automation can shift major

part of their consumption into

cheaper off-peak times

Intelligence Infrastructure

Smart Grid (Future Power Grid)

Generation drives demand

Dynamic Pricing

Energy Distribution optimization technologies

Integration of renewable generation becomes easierand more cost-effective

Self Monitoring, Healing...

What Is Smart Grid?

Networkof all advance power devices,

optimize electrical power generation, delivery

and use

Optimize power delivery and generation

Optimize Consumption, consumer participation

Self monitoring, self-healing

Accommodate generation options High quality power

. . .

11/19

Key Technologies

Integrated communications

Fast and Reliable communications for the grid

Allowing the grid for real-time monitoring, real-

time control, information exchange to optimize

system reliability, asset utilization and security

Wireless, power line or fiber-optics

For wireless: WSN (Zigbee...), WiFi, GPRS/3G, WiMAX...
