Grid, Smart grid, CURENT

Basic components of the Electric Grid

Power Plant- Electricity generationTransmission- Transmit electricity to different areasDistribution- Distribution to different loadsLoads- 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(??)

• What are renewable and non-renewable sources of energy?

Sources of Energy

U. S. Energy Consumption by Source, 2010

Transmission and DistributionTransformer:

Transmission:Step up voltage to kVDistribution:Step-down voltage to

120 VLines

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 storageTransmission Network

CURENTWhat 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
