What Is Smart Grid?
It is a power system architecture that permits two-
way communication between the grid and
essentially all devices that connect to it.
Under smart grid model , traditional generation still
has a large role, but it is augmented by distributed
generation in the form of wind , solar and various
other customer- owned generation sources that not
only generate electricity for end customers, but can
also sell electricity back to utility.
Today’s electrical grid suffers from a number of
problems, including :
Polluted (More than half of our electricity is generated
Less efficient (The delivered efficiency of electricity is
Vulnerable (The 2003 blackout in the Northeast
affected 55M people for up to two days).
Why do we need smart grid?
Conventional Power System
Cannot fully support the integration of renewable energy.
Major source is fossil fuel.
System is not much efficient.
Almost zero customer participation.
Existing Grid Smart Grid
One-way communication Two-way communication
Centralized generation Distributed generation
Few sensors Sensors throughout
Manual monitoring Self-monitoring
Manual restoration Self-healing
Few customer choices Many customer choices
Importance of Smart Grid
Improving energy efficiency.
