3. Introduction
• India is the third largest country in the world
Electrical transmission and distribution.
• So, Our country need a efficient and strong system to
for distribution.
• What is Smart Grid ?
Smart Grid is an integration of Electrical and
Digital technologies, information and communication
• Smart grid delivers electrical power to the consumers
using two way digital technology.
• Monitors the supply to the consumers and
measurements.

4. Existing Grid
• Limited Delivery System.
• High cost of power outage and power quality
interruption .
• Inefficiency at managing peak load.
• Communications too slow.

13. Advantages
• Integrate isolated technologies : Smart Grid enables
better energy management.
• Proactive management of electrical network during
emergency situations.
• Better demand supply / demand response
management.
• Better power quality.
• Increasing demand for energy : requires more
complex and critical solution with better energy
management

14. Disadvantages
• Present Infrastructure is inadequate and requires
augmentation to support the growth of Smart Grids.
• Most renewable resources are intermittent and can
not be relied on (in its present form)for secure
energy supply.
• Regulatory Policies to deal with consequences of
Smart Grid; like off peak, peak tariffs and other
related matters.
• Grid Operation : Monitoring & control

15. Conclusion and Future work
• The smart grid has been conceived as an evolution of
electric power systems due to the increasing diffusion
of distributed generation by renewable sources.
• This makes cost-effective remote sensing
technologies vital for safe, seamless and efficient
power delivery.
Future Work
• Security
• Up front consumer expenses
• Standardization
