Definition by Wiki

A smart grid is an electrical grid thatuses information and communication technology togather and act on information, in an automatedfashion to improve the efficiency, reliability,economics, and sustainability of the production andeconomics, and sustainability of the production anddistribution of electricity.


Smart Grid Conceptual Model

� Bulk Generation

� Transmission

� Distribution

Smart Grid - A large "System of Systems”

� Customers

� Operations

� Markets

� Service Providers

� Non-variable� Hydro

� Biomass

� Geothermal

� Distributes the electricityto and from the endcustomers

� Connects the smartmeters and all intelligentfield devices, managingand controlling them

Distribution Domain

Distribution

and controlling themthrough a two-waywireless or wire linecommunicationsnetwork.

� It may also connect toenergy storage facilitiesand alternativedistributed energyresources at thedistribution level.


Customer� The end-users of electricity

� Connected to the electricdistribution networkthrough the smart meters.

� The smart meters controland manage the flow ofelectricity to and from thecustomers and provideenergy information about

Customer Domain

energy information aboutenergy usage and patterns.

� Each customer has adiscrete domain comprisedof electricity premise andtwo-way communicationsnetworks.

� A customer domain mayalso generate, store andmanage the use of energy,as well as the connectivitywith plug-in vehicles.


Operations� Manages and controls theelectricity flow of all otherdomains in the smartgrid.

� It uses a two-waycommunications networkto connect to substations,customer premisesnetworks and otherintelligent field devices.

Operations Domain

intelligent field devices.

� It provides monitoring,reporting, controlling andsupervision status andimportant processinformation anddecisions.

� Business intelligenceprocesses gather datafrom the customer andnetwork, and provideintelligence to support thedecision-making.


Markets� The Markets domain operates

and coordinates all theparticipants in electricitymarkets within the smartgrid.

� It provides the marketmanagement, wholesaling,retailing and trading of energyservices. The Markets domaininterfaces with all otherdomains and makes sure they

Markets Domain

domains and makes sure theyare coordinated in acompetitive marketenvironment.

� It also handles energyinformation clearinghouseoperations and informationexchange with third-partyservice providers.

� For example, roaming billinginformation for inter-utilityplug-in-vehicles falls underthis domain.


Service Provider

� smart grid handles allthird-party operationsamong the domains.

� These might include webportals that provideenergy efficiencymanagement services toend-customers, dataexchange between the

Service Provider Domain

exchange between thecustomer and the utilitiesregarding energymanagement, andregarding the electricitysupplied to homes andbuildings.

� It may also manage otherprocesses for the utilities,such as demand responseprograms, outagemanagement and fieldservices.


It means everyone has to play their part effectively It means everyone has to play their part effectively to make our grid more efficient


Potential Benefits

� Optimizing the cost of existing production andtransmission capacity

� More renewable integration

� Improving power quality

� Improving utility’s power reliability, load anddelivery efficiencies ,asset management and overallproduction

� Consumer participation

� Self-Healing

Why we need such changes ?

Two grid disturbances affecting half of the country


Smart Grid Solutions??

Increasing Electricity Demand


Feasibility -smart grid ??

Coal shortage


Accountability –Smart Grid???

Energy loss is very high in India


Sustainable development in Power Sector


� Cost of power increasing

� Increasing system complexity

And the list goes on …….


Status of smart grid in India

� Smart city : Pondicherry� Demand side management.� AMI and DMS under R-APDRP.� PMU integration into the grid.� Smart power electronics devices ( HVDC, FACTS, SVC ) .� URTDSM Project.� URTDSM Project.� Renewable integration into the grid.� National transmission asset management centre.� Many more undergoing and many to come …..

So we are not far behind ....
