Utility: Loss/Utility operational efficiency improvement
Benefits of smart metering
• Active tracking of suspicious/ inactive meters and theft in real time, use of analytics
• Control of renewable integration, export only when utility needs it
• Enforcement of sanctioned load limit, IS 16444, Cl. 11.1, 11.2
• Improved and mistake-proof billing processes and efficiency, post and prepaid options
• Faster consumer complaint response time due to outage detection
• Customer service connection/disconnection convenience, saves efforts and time

Consumer and Societal Benefits
• Safety features against shock hazard, fire hazard
• DSM, flattening of peak demands, reduction in outages, personal energy management
• Smart In-home Systems – to provide energy information and consumption feedback
• Lower Energy Bills – by shifting consumption to off-peak periods and by conservation
Smart meter data and smart data analytics can be very useful for consumers

Linking smart meter data with end use
Genus Confidential 7
Interval data constitutes 77% of total throughput
Interval data is like omni bus

Problem of abundance
*Provided data is designed SMART
Genus Confidential 10
SMART Data, Block load profile IS 15959 (Part 2)
• Specific
• Measurable Interval data
1.0.99.1.0.255
Use, different capture parameters for different meters
• Accurate kWh import
kWh export
Real time energy accounting, modelling, forecasting
Real time energy accounting, modelling, forecasting
• Result oriented *Abnormality Need to incorporate for safety features (overload,
flags temperature, leakage, outages, low signal strength,
• Timely internet not connected etc.) for conservation of AMI
traffic
*There is a strong justification for a debate to re-design the interval data profile
Proposal to add abnormality flags

Smart use of DLMS: APDU Data Compression
Example Load Profile reading from 1P Meter for 8 IP with 6 channels
including RTC as per IS 15959 part 2, 300

array
Bytes in APDU Conventional With Null Vector for next With Compact Array* and null
Method RTC vector for next RTC
Bytes to be sent 278 (100%) 187 (67%) 142 (51%)
by Meter
*After taking up with DLMS UA, support of compact array is now included in CTT
Genus Confidential 12
Proposal to add more ‘Push’ profiles in IS
to reduce unnecessary data traffic, conserve resources and improve
reliability
Profile Push frequency Time division
Interval data compact array 5 minutes to 4 hours ( 5 min slots for
array of last 4 hour TDM
intervals) depending on
type of meter
Daily energy registers At midnight 5 min slots for
TDM
Billing data On billing date at 5 min slots for
midnight TDM

Safety feature, PoC to demonstrate smart meter as RCCB
RCCB, trip time 34.2ms Smart Meter, trip time 26.4ms
Genus Confidential 14
Smart meter as MCB (short circuit protection)
Smart meter can prevent short circuit fires
*With use of PGA’s management it is possible to detect short circuit from overload in mere 60ms
Genus Confidential 15
Conclusion
• Smartness lies in the information sent in AMI data for each end -use
– Specific
– Measured
– Accurate
– Result oriented—mapped to the end use
– Timely
• AMI data and push profiles need to be designed intelligently to meet SLA’s. Alarm
flag addition in interval data, smart data compression within DLMS framework
• Smart features can be added in smart meters to provide safety and transparency
to consumers through mobile Apps
• Smart analytics is the name of the game today
