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.

Page 3: Demand Side Management of a Smart Grid

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

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

Page 11: Demand Side Management of a Smart Grid

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

Page 12: Demand Side Management of a Smart Grid

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

Page 14: Demand Side Management of a Smart Grid

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

Page 16: Demand Side Management of a Smart Grid

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

Page 19: Demand Side Management of a Smart Grid

Smart Grid Enables Demand Response(DR)

Page 20: Demand Side Management of a Smart Grid

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
