What Is A Smart Grid Smart Grid is the modernization of the
electricity delivery system so that it monitors, protects and automatically optimizes the operation of its interconnected elements.
Smart grid is the integration of information and communications system into electric transmission and distribution networks.
The flow of electricity from utility to consumer becomes a two-way conversation i.e. two way flow of information.
Why Smart Grid? India is having one of the weakest
electrical grids in the world 10 to 20 % of power is lost to THEFT
across the utilities in India. 15-20% power transmitted is lost in the
transmission and distribution network Huge commercial losses due to poor
billing, metering, collection at depth etc
Features of a Smart Grid
Proactive management of electrical network during emergency situations.
Better demand supply / demand response management.
Better power quality Reduce carbon emissions. Increasing demand for energy :
requires more complex and critical solution with better energy management
Key objectives of a Smart Grid Self-healing: The grid rapidly detects,
analyses, responds, and restores Empowers and incorporates the consumer Tolerant of attack: The grid mitigates and is
resilient to physical/cyber-attacks Provides power quality needed by 21st-
century users: The grid provides quality power consistent with consumer and industry needs
Accommodates a wide variety of supply and demand.
Fully enables and is supported by dynamic electricity markets

• Asset Management• HVDC and
UHVAC etc.
• Self Healing Grids• WAMS
• Adaptive Islanding etc.
Smart Grid in Power Sector
SMART GRID IN DISTRIBUTION
Demand Optimization Smart Metering –
Automatic, Time of Use, Consumer Communication & Load Control
Communications : Automated Metering Infrastructure (AMI) – LAN, WAN, HAN
DRMS (Demand Response Management) In Home enabling technology
o Demand in three category: • Immediate, Deferrable, Storable
o Customer aggregation & De-aggregation required for Peak shifting
Advanced Sensing and Measurement
Enhance power system measurements and enable the transformation of data into information.
Evaluate the health of equipment, the integrity of the grid, and support advanced protective relaying.
Enable consumer choice and demand response, and help relieve congestion
Advanced Sensing and Measurement
Advanced Metering Infrastructure (AMI)o Provide interface between the
utility ad its customers: bi-direction control
o Advanced functionality• Real-time electricity pricing• Accurate load characterization• Outage detection/restoration
Advanced Sensing and Measurement
Health Monitor: Phasor measurement unit (PMU)o Measure the electrical
waves and determine the health of the system.
o Increase the reliability by detecting faults early, allowing for isolation of operative system, and the prevention of power outages.
ADVANCED METERINGINFRASTRUCTURE
The Key to Effective Demand Side Management
THE ADVANCED METERING INFRASTRUCTURE (AMI )
AMI is a basic element of the smart grid; its role is to furnish information and active interactive capability to service providers and customers
AMI consists of smart meters, integrated two way communications infrastructure, active customer interface, and meter data management system to gather and store customer data
In addition, AMI provides interfaces to other electricity company enterprise systems
THE SMART METER IN AMI
AMI Components: Smart Meter
The smart meter is the central nervous system of the AMI
The ability to collect consumption data in discrete time intervals allows the utilities to charge time differentiated rates for electricity usage
The meter can also perform other useful advanced functions, such as remote connect/disconnect
The meter is also a key need in the implementation of DR applications
Demand Side Management
Direct Load Management: Direct Load Control Interruptible tariff Demand Bidding
Indirect Load Management: Pricing programs Rebates Education programs
The financial status of power sector can be effectively improved by demand side management
Smart Grids and Local Energy Networks
Smart Grid Enables Demand Response(DR)
Achievements Changes in electric usage by
end-use customers in response to changes in the price of electricity over time is expected to produce major changes from normal consumption patterns.
This will help the utilities in undertaking effective management of power distribution.
Achievements of Demand Optimization
Energy Usage Information
Efficient Communication between Utilities and Customers
Consumer Enrollment in DR programs In Home Technology- Availability &
Purchase , Device Provisioning
