Electricity automation history
1920s
• Supervisory Control and Data Acquisition (SCADA) to operate remote devices
1930s
• Interconnection between grids to balance generation (supply) and load (demand)
• Analogue computers
1950s
• Economic Dispatch and Automatic Generation Control to automatically dispatch lowest cost generators
1960s

Data Solutions
o ASSET INTELLIGENCE :
▪ “a computational framework ensuring that well-chosen data streams
collected by smart network assets are optimally utilised”

CASE STUDY: PREDICTIVE ASSET RATING
![Page 16: The application of MATLAB in Unisons Smart Grid](https://reader031.fdocuments.in/reader031/viewer/2022012513/618cea354ccc41064e3574d4/html5/thumbnails/16.jpg)

What is rating?Rating – upper limit of current or power we subject our
asset to
Determines if we can supply the demand and when we
need to upgrade our assets
![Page 17: The application of MATLAB in Unisons Smart Grid](https://reader031.fdocuments.in/reader031/viewer/2022012513/618cea354ccc41064e3574d4/html5/thumbnails/17.jpg)

Decisions decisions..
What current can I put on these assets
without overloading them?
When do I need to start upgrading these
assets?
Will the investments I approve still be
required in 10 years time?

Rating options
A. Manufacturers rating - near worst-case scenarios
of weather and load conditions. E.g. transformer
rating is based on 30 degrees C of air
B. Dynamic Rating – adaptive to changing
environments conditions
C. Predictive Rating – forecast environmental factors
using AI to schedule loading accordingly

Case Study: Dynamic and Predictive Feeder Rating
• Implemented Dynamic and
Predictive Feeder Rating for 7 pilot
feeders
• Predictive: Forecast weather 6
hours ahead and calculate
corresponding rating
• Dynamic: Update rating calculation
every 30 minutes
![Page 24: The application of MATLAB in Unisons Smart Grid](https://reader031.fdocuments.in/reader031/viewer/2022012513/618cea354ccc41064e3574d4/html5/thumbnails/24.jpg)

Dynamic Cable Rating
• Use soil thermal resistivity and
cable temperature to determine
rating
![Page 25: The application of MATLAB in Unisons Smart Grid](https://reader031.fdocuments.in/reader031/viewer/2022012513/618cea354ccc41064e3574d4/html5/thumbnails/25.jpg)

Dynamic Lines Rating
• Use weather station
data, line temperature
and line clearance to
determine rating
![Page 26: The application of MATLAB in Unisons Smart Grid](https://reader031.fdocuments.in/reader031/viewer/2022012513/618cea354ccc41064e3574d4/html5/thumbnails/26.jpg)

Control room view
• Increased operational flexibility and
resilience
• Helped during extreme event like
Cyclone Cook
• Less risk of lost load using real-time
and predictive data
• Greater confidence in line clearance
and asset condition for pilot feeders

Asset Management
• Dynamic and Predictive Rating provides data driven
decision support for network operations and planning
• Real time data reduces the risk of asset failures
• Additional ratings provide a significant (30-50%)
increase from manufacturer’s rating
• Non Network Solution to defer capital investments and
manage risk of stranded assets
