Smart Grid Operational Strategies that Utilize :

Interoperability Standards

© Yadav Measurement | Marketing | 6

Smart Grid Interoperability Standards

• Supports one or more of the following

– Make it easy for consumers to use smart devices regardless of

location and provider

– Protects privacy while enabling consumers to securely access

information on their own energy consumption

– Prevents premature obsolescence, facilitates future upgrades,

ensures systems can be scaled up, and extends lives of legacy

equipment

– Expands product markets and promote vendor competition:

reducing costs, accelerating innovation, and increasing choice

– Ensures the security and enhances the reliability of the power grid

Some of the bodies working for

Smartgrid standardization

• IEC

– Has identified about 300 standards to be worked

upon

• NIST

• IEEE

• Various smart grid forums

• CEA / PGCIL

Components of AMI

In home Display, (being a consumer device, it is generally kept out of the scope

of AMI)

An advanced electricity meter,

An appropriate two way communication system between each of the above core components this binds them together.

AMI Component : In Home Display

• Intent is to involve consumer.

• Interactive: Displays energy, money, Critical price and CO2.

• ICON intensive – meant for mass public

• Self powered

• Wiring less: Wire less

Home Area Network (HAN)

• HAN: Communication between single meter and multiple In-Home devices.

• License free, interference tolerant wireless operation: Zigbee 2.4GHz

• Mesh architecture from Zigbee to combat interference.

• Other load control devices

Key AMI requirements

• kWh-Import

• kWh-Export (for embedded Generation)

• KVArh-Lag

• KVARh-lead

Metrology :Half hourly consumption

for 4Q

• For settlement, daily sales figures are needed by 07:00 hr. Hence the data for previous day should be collected from 24:00 hr to 04;00 for 99.8% of meters,

Daily remote meter reading 00-04:00 hr

• Electricity rules requires that on vacancy, the service fuse should be pulled out,

• How much would a disconnection cost in India?

Remote/ local load connect/

disconnect

• Upon remote re-connection, there is a chance that a heater/ iron could have been left in the socket. Upon energisation- this could cause fire.

Prepaid Metering

•Customers who either want a lower rate or have a history

of slow payment can benefit from prepayment of power.

•Smart metering makes it easier to deploy new types of

prepayment to customers and provide them with better

visibility on the remaining hours of power, as well as

extending time of use rates to prepayment customers.

•AMI systems can also trigger notifications when the

prepayment limits are close to being reached and/or have

been exceeded.

•Limited Energy Usage Limited Demand
