About Smart Grid

No Simple Definition

Smart : Intelligent , Interactive.

Conventionally Electricity grids are dumb.

A 33 KV feeder tripping can black out entire area it

powers.

Locating a line fault due to line coming in contact

with branch of a tree is tough task for a line man.

About Smart Grid

No Simple Definition

Fault in Distribution system can drag EHT system to

its knees in a dumb ele network.

Peak Load Management is a daunting task for SLDC.

About Smart Grid

No Simple Definition

It is difficult to trace series of cause-and-effect chain

of events when a serious electrical fault occurs.

Power Quality is seldom maintained in Distribution.

About Smart Grid

No Simple Definition

In a country / state wide EHT network the complex power injections and loads can lead to phase differences between different power parameters. A unhealthy electrical situation.

cause casualties for human life and Elephants in

particular.

About Smart Grid

No Simple Definition

About Smart Grid

Smart Grid is a journey like Smart City

The SG initiatives are capital intensive.

Paucity of Funds result in drafting SG Road Maps.

And staggered materialization of Activities.

We need to keep on refining our grids.

It is like a long journey.

About Smart Grid

Efficiency, Performance, Reliability, Control etc.

Grids become rational, intelligent and responsive.

Self healing

Self diagnosing.

The grids can truly become Economic drivers.

Conclusions

Smart in the context of Odisha

Government of Odisha

formed a Odisha Smart

Grid Steering Committee

during 2014.

The committee chaired by Secy, Energy, GoO, Members include CMD OPTCL, DG CPRI, expert from PGCIL, ex DG CPRI Sri AK Tripathy, Former Member OERC Sri BC Jena..

Smart in the context of Odisha

All power utilities of the

State, OREDA, GEDCOL,

are in the focus for the

initiative.

The committee is

entrusted to come up

with Smart Grid Road

map for the state by

applying SGMM

framework.

Smart in the context of Odisha

SGMM is a management

tool leveraged by the

Utilities to plan their

Smart Grid Journey.

Utilities can prioritize

their tasks and measure

their progress as they

realize the set tasks.
