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
Global Warming - The Threat !!• Improving Energy efficiency• Renewable Energy sources• Carbon capture and sequestration• Reducing Peak demand
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
The Traditional Power GridIf Alexander Graham Bell were somehow transportedto the 21st century, he would not begin to recognizethe components of modern telephony – smartphones, texting, cell towers etc. – while ThomasEdison, one of the grid’s key early architects, would betotally familiar with the grid.!!
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
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
Enabling Smart Grid• Local Energy Networks• Energy Storage• Electric Transportation• Robust and cheap network devices• Large Data storage
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
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
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

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.
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
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
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
Disadvantages (contd.)• Not simply a single component• Various technology components: software, the power generators, system integrators, etc.• Expensive in terms of installation
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
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.
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.
SummarySmart Grid is an emerging technology to provide nextgeneration power grid and is promoted by manygovernments as a way of addressing energyindependence, global warming and emergencyresilience issues.
