Challenges:
Turning Data into Opportunity & Value“The world generated five Exabytes*
of data between the dawn of
civilization through 2003….. Erich Schmidt
2010 That amount of data is now
created every two days.”
*1 Exabyte = 250 Million DVDs
That rate is estimated to have Doubled since 2010
Challenges:
Turning Data into Opportunity & Value• From 1 Meter Read/mo to Hourly (720/mo)
• =71,900% increase in Data (((720-1)/1)*100%)
Our industry is no Different
• No. Of PMU’s installed has
doubled in the past 12 months
• Generating Terabytes of data
• Transitioning from
Implementation to Analysis
Management (Optimization) of the Grid = Management of Data
Distribution Application Examples Turning Data into Value
Advanced Data Mining Algorithms Create
Additional Value – Improve GIS & Distr. Apps
AMI Enabling Automatic Customer Phase ID
• Improve GIS - Automatically maintain accurate phase (A, B or C) association of every customer
• Benefit outage management, enable advanced volt/var optimization, improve distribution efficiency
Clustering algorithm on voltage drop/rise data during capacitor bank
operation uncovers customer connectivity
with phase C
Distribution Application Examples
• Using AMI data to Auto-Generate Secondary Circuit Models
• Using AMI and Sensor Data for Distribution State Estimation
• Combine data from similar circuits and weather data to identify benefits
• Pattern Recognition - Using Feeder Monitors to Locate Faults and Estimate Cause
• Trends & Forecasting – Detecting Stressed Assets
Transmission Application Examples Turning Data into Value

Transmission Application Examples
• Combine Synchrophasor & Other Data for:
– Disturbance Location Identification – Dynamic Model Development &
Validation
• Synchrophasor-Based Early Warning of Inter-Area Oscillations
• Sensor Data - The Source of Asset Condition Information

Enabling Infrastructure Examples
Enabling Infrastructure May Apply to both Transmission & Distribution
Enabling Technologies that are Emerging
• Enterprise architecture
• Visualization technology
• Database technology
• Standards for interoperability
