3. Objectives
• Understand the need for overhaul and modernization
of the existing power system
• Appreciate the necessity of Smart grid
• Understand the key components of the Smart grid and
its implementation
• Know the benefits and the challenges involved in the
Smart grid
4. Global Warming - The Threat !!
• Improving Energy efficiency
• Renewable Energy sources
• Carbon capture and sequestration
• Reducing Peak demand
5. Smart Grid - What is it??
• Network created through the combination of
Information Technology, Communication Technology
and Electrical Power System.
• A grid remarkable in its intelligence and impressive in
its scope which offers valuable technologies that can be
deployed within the very near future or are already
deployed today
• It simply means, a “smarter “ power grid
6. The Traditional Power Grid
If Alexander Graham Bell were somehow transported
to the 21st century, he would not begin to recognize
the components of modern telephony – smart
phones, texting, cell towers etc. – while Thomas
Edison, one of the grid’s key early architects, would be
totally familiar with the grid.!!
7. The Traditional Power System
• The present infrastructure is overstrained and inter
region bulk transfer is limited
• Cannot fully support the integration of renewable energy
• Low reliability of Power - Outage
• Fluctuating quality of Power
• Major source is fossil fuel
• Efficiency of Power transmission
• Almost zero customer participation
• Low Billing and collecting efficiency
8. What Smart Grid does??
• Decentralization of Generating resources
• Integration of all sources of energy, mainly renewable
• Continuous monitoring and feedback from the network
• Anticipation of faults and helps in fault prevention
• Establishes a two-way communication between the
utilities and the consumers
• Reduces the stress on the power system infrastructure
• Reduces and shifts the peak demand
• Continuous self-learning
9. Enabling Smart Grid
• Local Energy Networks
• Energy Storage
• Electric Transportation
• Robust and cheap network devices
• Large Data storage
10. Energy Storage
• Ultra-capacitors, Li-ion, Vanadium redox batteries and
Fuel cells
• Used in PHEVs and storage of intermittent renewable
energy
• Flywheels and Pump storage - Mechanical
11. Electric Transportation
Plug-in Hybrid Electric Vehicles(PHEVs)
• Efficient means of transportation
• Can be recharged at night during low cost periods
• Can provide grid support during peak periods
• Reduces oil imports and pollution drastically
12. Local Energy Networks
• Micro grids covering small geographic area
• Can generate power even when power from a utility is
absent in case of emergency or disaster - Islanding
concept
• Combining distributed resources the community can
generate sufficient electricity to keep the grocery
store, the police department, traffic lights, the phone
system and the community health center up and
running
29. Advantages of Smart Grid
• Economic Development
o New Jobs: The manufacture, installation, operation
and maintenance of the smart grid and its
components will create new jobs within the state.
o Innovation: Smart grid innovation will enable the
growth of business while rewarding customers with
valuable new products.
30. Advantages of Smart Grid (Cntd.)
• Lower Costs: Costs rise over time and energy is no
exception, but the smart grid should provide less
costly energy than otherwise would be possible. As
such, it will save customers money which can be
invested or consumed as they choose.
• Higher Customer Satisfaction: The combination
of lower costs, improved reliability and better
customer control will raise satisfaction among all types
of customers
31. Advantages of Smart Grid (Cntd.)
• Improved Reliability: Smart grid will reduce and
shorten outages and improve the quality of power.
• Customer Energy/Cost Savings: As pricing
becomes more transparent and is aligned with the
underlying economics of generation and
distribution, customers’ decisions to save money will
benefit society as well
32. Disadvantages of Smart Grid
• Biggest concern: Privacy and Security
• Some types of meters can be hacked
• Hacker:
gain control of thousands, even millions, of
meters
increase or decrease the demand for power
33. Disadvantages (contd.)
• Not simply a single component
• Various technology components:
software, the power generators, system
integrators, etc.
• Expensive in terms of installation
34. Smart Grid’s Future
• In the near future, there will not be any vast
development
• Initially there is requirement of huge financial
demands and regulations.
• In the long-run, attitudes will change, wide spread
usage of the smart grid from every business to
every home just like the Internet
35. Money Matters
• India Smart Grid Task Force (ISGTF) initiates pilot
projects in eight different locations over the next 18
months, with a total cost of $132 million (Rs. 600
crore).
• Asian Development Bank to lend India $759 million
• NDPL receives $686,447 grant for
Smart Grid project.
36. Projects in India
• Bangalore Electricity Supply Company (BESCOM) has
been chosen as the distribution utility that will
implement the first pilot project of smart grid in India
• A smart mini-grid (SMG) or micro-grid using only
renewable energy sources has been commissioned at
The Energy Research Institute’s (TERI), Gurgaon
campus.
37. Summary
Smart Grid is an emerging technology to provide next
generation power grid and is promoted by many
governments as a way of addressing energy
independence, global warming and emergency
resilience issues.
