1 1 Big Data Analytics Applications in Distribution Operations and Risk Assessment Edwin C. (Ed) Carlsen Manager - Distribution Management Systems, Georgia Power eccarlse@southernco.com, e.carlsen@ieee.org

2 2 Panel Title / Topic Big Data Analytics Applications Distribution Operations Risk Assessment Trigger some ideas and discussion

3 3 Big Data and Analytics Just AMI? GPC before AMI 53 million reads per year

4 4 Big Data and Analytics Just AMI? GPC before AMI 53 million reads per year GPC after AMI 154 billion reads per year not including meter events

5 Lot s of other data with the distribution grid 5 4.4M Customers 3.4 million distribution poles 1.6 million street lights 1.4 million transformers 150,000 mi. of distribution line

6 6 Customer Data AMI Data Distribution Grid Data Outage Tamper Temperature Reverse power flow Current Voltage Phase angles Power factor Frequency Business Decisions Operations Billing Revenue Protection Marketing Customer Satisfaction

7 Analytics = Data Insight Action 7

8 Analytics = Data Outage Reports 8 Customer Phone or web site SCADA AMI Electrical Model

9 Analytics = Data Insight Outage Reports OMS Work Agenda 9

10 Analytics = Data Insight Action Outage Reports OMS Work Agenda OMS Crew Actions 10

11 11 OMS Enhancement AMI Data Objectives o o Enhance outage response and restoration Improve outage communication to customers Utilize power off and power restore signals from AMI Utilize pinging of meter to obtain current status Simple Concept, but involves complexities B A C

12 Filtering (analytics) required for AMI-OMS 12

13 13 AMI-OMS: Enhanced Analytics What % of outages occur in the middle of the night (or the day) without customer calls? What % of AMI meters report outage events? What % of AMI-reported events create incorrect outage predictions (due to data quality, timing or other issues)? How timely was the data reported? Do weather conditions impact data quality? How does data volume impact quality? Can we use the AMI outage info to correct data issues? Data sources needed: AMI, OMS, SCADA, GIS, CIS

14 Fault Location Analysis (FLA) The Question Can we utilize fault data from electronic relays to accurately locate faults on distribution circuits? 14

15 15

16 16

17 OMS FLA System Integration Data flow from relays via SCADA, ICCP Integrating impedance data and field device data into OMS New functionality in OMS New work processes SCADA ICCP B R 17

18 Fault Location Analysis (FLA) The Question Can we utilize fault data from electronic relays to accurately locate faults on distribution circuits? The Answer Yes! Predicts in less than 1 minute, often within 5-6 spans of trouble Enhanced Analytics Desired: How often is it correct? How close to actual trouble? If incorrect, why? What additional information is needed? 18

19 FLA Pinpointing Fault Location / GPS Position Capture Capture trouble location 19

34 Outages Customer Communication 34

35 35 Customer Outage Communication - Enhanced Analytics Are we providing accurate/timely outage information? Is the information getting to customers in a timely manner? Are customers receiving the information they want? Are we under/over communicating? Are the business processes and technology adequate to provide desired outcome? How much is does it (or will it) cost per channel? Per event? Data sources needed: OMS, Outage Communication Systems (maps, text, voice, ), CIS, Accounting.
