What Exactly Is A Smart Grid? Smart Grid Applications

Smart Grid & Their Application in the Grid System

What is Grid?

Concept of smart grid is quite in the news and market but majority of the people actually don’t know that what exactly are the things which make a grid smart?

The term “Grid” refer to an “Electric Grid” basically describes a complete network which includes transmission lines, transformers, distribution substation all accessories that are used for delivery of electricity from generation plants to home and commercial scale.What is Smart Grid?

The very first grid was built in decade of 1885-1895 and the with the passage of the time number of grids kept on increasing that’s why by now there are about more than 9200 grids all over the world which are providing about 1 million Megawatt power to the consumers.

As evolution has a direct relation with time so for an efficient functionality of grid, digital technology has been introduced in grid system. This new digital technology enables two way communications which guarantees the direct link between utilities and all consumers.

What is a Smart Grid Then?

In simple words, an automation system between utility and consumers. This smart grid consist of advance digital system, automation, computer and control which make sure to perform a duplex “two way” communication between the power provider and load consumer. 

In a typical electrical grid system, electricity provider only will know the power failure when a costumer call them. But in case of smart grid system, if electric supply fails, service provider will automatically respond to the affected area because the components of smart grid  provides enough data i.e. from the power transformer, main transmission and distribution system and finally, to the home supply system (you may say the utility meter).

What Things Make a Grid “Smart”?

According to the Department of Energy (United States), Four types of advance technology will transform a typical electrical grid into Smart Grid which are as follow:

  1. Fully automated and Integrated two way communication between the overall components of an electric grid.
  2. Automatic Control for power distribution, faults and repairs.
  3. Advance management panel, decision support software and mechanism.
  4. Accurate sensing and measurement technologies.

What is exactly a smart grid and their operations?Upgraded technology of smart grids has well-organized automation equipment and control system, whose response is accurate to meet the rapidly increasing demand for electricity. Time when these smart grids were not implemented all utilities companies were bound to send their respective workers to take meter reading and acquire data related to consumer.

What Does a Smart Grid Do?

Smart grid performs lots of smart jobs :) . Some advantages of a smart grid are stated follow:

Efficient Transmission and Distribution of Electric Power.
Quickly restore electric power after power failure due to faults.
Lower cost for operation, maintenance, management  and electricity for both utilities and consumers.
Lower electric power tariff and rates due to reduced peak demand.
Provide better options of integration of renewable energy for self power generation systems.
Improve the security and protection.

Applications of a Smart Grid System.

Deployment of Digital Technology in smart grids ensures the reliability, efficiency and accessibility to the consumers regarding all utilities which count towards the economic stability of the nation. Right at the start of transition time it become perilous to execute testing, to improve the technology by up gradation, developing and maintaining standards on a standard threshold and also application of these efficient grids serve all these problems

Basic applications of smart grids are

  • They improve the adeptness of transmission lines
  • Quick recovery after any sudden breakage/disturbance in lines and feeders
  • Cost Reduction
  • Reduction of peak demand
  • They possess the ability to be integrated with renewable energy sources on a large level which leads to sharing of load and reduction of load on large scale

What does a Smart Grid do?


In these days disruption of power supply is very common issue faced by majority in which any fault in feeder or main distribution lines lead to a complete blackout due to which whole system will be out of order and functionality of industries will be stopped.

But smart grid system has capability to secure the system on the spot by handling emergencies because they possess the ability of automatic rerouting in case of any fault current . Smart Grids are not only providing the link between consumers and utilities moreover they enable users to handle their electricity usage systematically like we use online banking from anywhere any time.

Management of electricity in well-organized matter will clearly lead to cost reduction. One of the interesting application is smart meters. With the help of smart meters we need not to wait a whole month to get electricity bill rather we can see reading and receive bill daily online which will obviously save money for consumers and save electricity or power for whole country which will provide support in economical stability of the country.

Coming toward the precautions as this system has wide range of technical data and equipment along with automation equipment and protocols, so most important thing will be to ensure whether the system is properly installed because, if there will be no loop holes in deployment of this technology, smart grids on global level will bring revolution in power sector same as internet did transformation in the World of IT.

  1. Hi diar iam wahidullah electrical eng from afghanistan when i see uor websit i so happy becuas this sit has evrething that i need in my job and uor realy hard worked on this site best regrad

  2. you will have to chande the wriing due to the wriing for the 120v can not old the power that would go thru a 30/50 amp breaker.The lines to replace would be priced by foot.You just need to run a dedicated line and use a 30amp breaker.depending on how long of wire you have to run an electrician could cost from 300.00 and up just to do this.breaker depending on the type you have can run from 40.00 and up. A culter hammer 30 amp cost me 70.00.If you don’t know anything on how to wire inside of the electricial box I would advise you call an electrician.
