Grid, Smart grid, CURENT
Basic components of the
Electric Grid
Power Plant- Electricity generation
Transmission- Transmit electricity to different areas
Distribution- Distribution to different loads
Loads- Industries, Residences, etc.

Electric Grid
▫ Converts different forms of energy to
electricity (generation)
 Forms of energy conversion (??)
▫ Transmits electric energy from one place to
another (transmission) (how??)
 Challenges(??)
a)Less losses b)Long distances
c) No wire cut offs
▫ Distribute to residential and industrial loads
(Distribution)
 Challenges(??)
Sources of Energy
• What are renewable and non-renewable sources
of energy?
U. S. Energy Consumption by Source, 2010
Transmission and Distribution
Transformer:
Transmission:
Step up voltage to kV
Distribution:
Step-down voltage to
120 V

CURENT National Science Foundation Engineering
Research Center.(
)
A collaboration between universities, industry and national labs.
Center for Ultra wide Resilient Electric Energy Transmission
Networks.
Ultra wide ????A nation-wide or continent-wide transmission grid.
Resilient???? Able to withstand and overcome overload or
stressful/disturbed conditions
How??? Develop a system that is fully monitored
and dynamically controlled in real-time.
Why?? high efficiency, high reliability, low cost.
Electric Energy - renewable energy sources, energy storage

What we do not do
▫ Generate, transmit or distribute energy
 That is what electric grid does!!
What we do
 Monitor grid data,
 Analyse the various disturbances/overloads
 Develop control methods to improve and make
the transmission grid resilient
