1 Data Challenges in Improving Outage Resiliency in Distribution Control Centers Gary L. Ockwell PE CTO / ACS EPCC 14 May Wiesloch Germany

2 Distribution Control Center Outage Resiliency is related to data management Typical ADMS Data sources: Real-time telemetry (SCADA) Near real-time telemetry (AMI) Application generated data (DMS, OMS) Crew information w/ network updates Customer formal reports (calls) Customer informal reports (social media) Distribution CC operator handles data collected under various time domains, delivered by various systems

3 Technical Complexity Non-integrated Control Center systems Transactive grids independent Renewable Storage & Cntl Centralized Large networks - DERMS Extensive deployment Self healing Volt/ PV/DER/ energy storage VAr Medium / small networks DMS Distributed Feeder Automation (model) D-SCADA AMI OMS Existing 5 years 10 years 15 years Implementation Milestones

4 Technical Complexity Functional ADMS Microgrids Centralized Transactive grids Self healing Renewable Storage & Cntl Volt/ PV/DER/ energy storage VAr Medium / small networks AMI independent Large networks - DMS Distributed Feeder Automation (model) D-SCADA OMS ADMS DERMS Large networks - Existing 5 years 10 years 15 years Implementation Milestones

5 Network Operations: Transmission versus Distribution Transmission network Distribution network Advanced network apps 100% devices have TM Aggregated loads Schematic diagram Little crew coordination Minor public involvement Advanced network apps 10% devices with TM Individual loads Geographic diagram Excessive crew coordination Direct public involvement

6 Model / Database Comparison SCADA Vs DMS Database Size Comparison 2,500,000 2,000,000 1,211,541 1,500,000 1,000,000 Analog Status 1,156,440 Actual utility: before and after same comparison 500,000 42,015 41,949 0 (Cobb EMC) SCADA Total DMS Total

7 Stress ADMS Performance - 12 hour Measurement Actual recorded # of active outages: Peak # of active outages (per hour): Quiescent Trouble Calls per hour: Actual results > 1 million > 125,000 per hour 129,510 per hour # of customer calls: 436,302 Storm Trouble reports per day (taken from all sources: IVR, AMI, Call takers): > 791,690 Concurrent users in the test scenario of all tasks, including Call takers: 325 # of HTTP requests to the Web server: 2,178,469 Total transactions passed: 1,102,949

8 Prime Objective: Improve Outage Resiliency

9 Quality of Data Goal: Improve Outage Resiliency 3 Outage technologies to improve resiliency Restore TM DA w/load flow, Automation TM SCA crew Switch crew w/lf, no Auto AMI TCA crew w/no LF, no Auto Call crew fault location determination x sec xx minutes Relative Restoration Time > hour

10 Quality of Data Goal; Improve Outage Resiliency through Crew & Social media Restore TM DA w/load flow, Automation TM SCA crew Switch crew w/lf, no Auto AMI TCA crew w/no LF, no Auto Calls Social x sec xx minutes Relative Restoration Time > hour

11 Georgia Power s Centrix Project Progress 410 Feeders 1,450 Automated switches and reclosers 654,587 Customers on Centrix 131 Centrix Islands 64 restoration operations in ,694,852 CMI avoided

12 Georgia Power s Centrix Success in Outage Resiliency 770 Feeders 1.2 M Customers on Centrix 2016 > 39M CMI avoided

14 Crew mobile efficiency

15 Advantages of tight crew coupling Human Grid Model topology maintenance Crew safety Improved network situational awareness Improved efficiency Minimal operator interaction Improved accuracy Improved audit and documentation Improved customer communication (ETR)

16 GridVu public: outage communication 3 steps to Report outage: 1 - Sync account 2 - Report outage type 3 - Send report & receive updates What do you see? Tree damage Wire down Fire No lights

17 GridVu public: outage communication 3 steps to Report outage: 1 - Sync account 2 - Report outage type 3 - Send report & receive updates Outage Summary: Address affected: 73 Blue st. Akron, OH Tree damage Contact Number: Sign me up for proactive updates Report outage

18 Postal Service Landline Mobile WWW Texting Smartphone Mobile Apps 550 BC & Social Baby Boomers <75,000, Generation X 66,000,000 Millennials >81,000,000

19 OUTBOUND crew access public access Hyperlink (SMS) Facebook Twitter OUTBOUND Hyperlink (SMS) Facebook Twitter Web browser INBOUND Facebook INBOUND Hyperlink (SMS) Web search Facebook wall Twitter Hyperlink (SMS) Web search Facebook wall Twitter

20 Advantages of tight public coupling Overall call volume reduction Improved public communication Improved customer satisfaction Improved restoration performance Less frustration for everyone during outages
