4. WHAT IS SMART GRID ?
DEFINATION :-
4
IN SIMPLE WORD:- Two way transmission of electrical energy and two
way communication is known as smart grid.
OR
IN OTHER WORLD:- A "smart grid" is an electrical grid which includes a
variety of operational and energy measures including smart meters,
smart appliances, renewable energy resources includes a variety of
operational and energy measures, and energy efficiency resources.
6. NEED OF SMART GRID :-
1. To satisfy the increase demand of growing population .
2. To minimize the Transmission and Distribution losses .
3. To Integrate the renewable energy sources into the system to
reduce the dependency over the fossil fuel and would get pollution
free energy .
4. To set up a communication channel between utility and consumer .
5. To make fault detection , isolation and restoration easier and
convenient .
6. For Advance Metering Infrastructure (AMI) .
7. For Cyber Security .
8. For Distribution Grid Management .
9. For Energy Storage 2

Reliability- By reducing the cost of interruptions and power quality
disturbances and reducing the probability and consequences of widespread
blackouts.
Economics- By keeping downward prices on electricity prices, reducing the
amount paid by consumers as compared to the “business as usual” (BAU) grid,
creating new jobs, and stimulating the U.S. gross domestic product (GDP).
Efficiency- The smart grid can improve load factor and reduce system
losses , by reducing the cost to produce, deliver, and consume electricity.
Environmental- By reducing emissions when compared to BAU by enabling a
larger penetration of renewable and improving efficiency of generation,
delivery, and consumption.
Security- By reducing the probability and consequences of manmade attacks
and natural disasters.
Safety- By reducing injuries and loss of life from grid-related events
Benefits of Smart Grid :-

1. RESILIENT GRID:-
11
It is operated , command , instruction
by the human .
Basic work of resilient grid are to
prevent initial failure and reduce their
magnitude .

2. SELF –HEALING GRID :-
Self-Healing grid regularly check the working status
of the system .
The process of pre-fault ,during-fault and post-fault
is being perform automatically of the system .
Self-Healing grid is operated without any human
command and instruction .
Automatic troubles swinging and facility of the
smart grid .
13. KEY DRIVER IN SMART GRID :-
13
1. INTERNAL MARKET :-
• Liberalization
• Competitiveness
• Low price
2. SECURITY OF ENERGY SUPPLY :-
• Energy availability
• Reliability and quantity capacity
3. ENVIRONMENTAL :-
• Global warming
• Climate change
• Pollution
14. CHALLENGE IN SMART GRID :-

CONCLUSION :-
By using smart grid technology energy can be utilized to maximum and would not be wasted .
This technology also helps to save earth from global warming .
It refers to the modernized version of the earlier traditional method of energy supply.
THINK ‘SMART’!!!
