The document summarizes a technical seminar presentation about smart grids. It begins with an introduction to smart grids, noting their origins 15-20 years ago as a way to add sensors and software to existing power grids. This allows for two-way communication, self-healing, distributed power generation from multiple renewable sources, and consumer choice. Benefits of smart grids include awareness of peak hours, reduced emissions and costs, integration of renewable energy, instant consumption and production feedback, and support for electric vehicles. The future of smart grids is presented as essential for sustainability, with investments of billions of dollars being made in smart grid projects worldwide.

3. ORGIN STORY
15 – 20 YEARS AGO NOW

4. ENERGY CONSUMPTION IN INDIA SOURCE

5. NORMAL GRID
• POWER LINES BREAK OR POWER PLANTS CANNOT PRODUCE ENOUGH ELECTRICITY BLACKOUTS(POWER FAILURE)
CAN OCCUR
• NO DETAILED INFORMATION ABOUT USAGE & DIFFICULT TO MANAGE
• TIME CONSUMING (WORKERS TO SOLVE AND RE SUPPLY THE POWER)

6. SMART GRID
• ADDING SENSORS AND SOFTWARES TO EXISTING GRIDS SO BOTH THEN CUSTOMERS AND
EMPLOYEES CAN REACT TO CHANGES QUICKLY
• REROUTE TO ANOTHER GIRD DURING FAILURE
• POWER GENATION SPLIT TO MULTIPLE SOURCES(SOLAR , WIND ,ETC)
• Found in 2007 by United states energy Dept

7. BENEFITS TO SMART GRID
 Makes people aware of PEAK HOURS(Smart Meters)
 Reduce emissions & Reduce fuel costs
 Integrate different sources of renewable energy into a single grid,
 Provide instant feedback on energy production and consumption & Make
diagnosing faults seamless
 Provide energy according to demand, making it more efficient
 Generating more efficient renewable power
 Working with smart devices and smart homes &Paving the road for electric vehicles.

8. TRADITIONAL GRID
SMART GRID
 ONE WAY COMMUNICATION
 MANUAL HEALING AND MANUAL MONITORING
 FEW CUSTOMER CHOICES
 CENTRALIZED GENERATION
 TWO WAY COMMUNICATION
 SELF HEALING AND SELF MONITORING
 MANY CUSTOMER CHOICES
 DISTRIBUTED GENERATION

9. SECURITY IN THE SMART GRID
Availability: Ensuring timely and reliable access to and use of information is an essential component of the
smart grid. Without actionable, real-time, and reliable access to data, the benefits of the smart grid simply
cannot be realized. How data is collected, distilled, and shared is highly important, and security solutions must
support these aims by avoiding negative effects on availability.
Integrity: The smart grid depends on reliable and accurate data. To prevent fraud and other more harmful
attacks measures must be taken to ensure that data is accurate and free from manipulation.
Confidentiality: The smart grid generates huge volumes of data which must be collected, stored, and
analyzed. Some of this data will include sensitive details about consumers and the utilities themselves. Steps
must be taken to prevent unauthorized disclosure of sensitive information.Eg : MOBILE PHONE COMPANY
Accountability: Accountability is the idea that users of a system should be responsible for the actions
they perform. This means that user interactions with sensitive systems should be logged and associated with a
specific user. These logs should be difficult to forge, and have strong integrity protection.

10. FUTURE OF SMART GRID
 The benefits of the smart grid are numerous, and one could argue that smart grids will be
essential to the sustainability of a modern society.
 In fact, according to some power retailers, energy costs could increase as much as 400% in
western countries that fail to deploy smart grids.
 IN India MINISTRY OF POWER working on Smart Grid Mission
 With over 13.3 million smart meters forecast to be shipped and $2.7 Billion invested as part of
smart grid projects in the United States in 2016 alone.
 Eg: In Hawaii average electricity bill > 3 times north america , which lead to 12 % population use solar panel on
their homes , the power company has to pay customers for the use of their electricity.3 With fewer paying
customers, there is less revenue to maintain the system. In 2016 these economic realities resulted in Hawaii
putting a halt to further solar DER deployments on the island
