1 Challenges of DMS Control Centers in the Smart Grid Gary Ockwell Efacec Advanced Control Systems Chief Technology Officer June 5, 2013

2 Affected: 30 Million Inhabitants 800,000 in trapped subways 250 Flights at JFK 150 Hospitals Utilities had minimal information and control capability to monitor and restore service led to the creation of SCADA / EMS... DMS and to the formation of NERC in 1968

3 Aug 14 / 03 Blackout NERC Report: Root Cause 1: FE Situational Awareness Root Cause 2: Vegetation Management Root Cause 3: Reliability Coordinator Ineffective Diagnostics 90% of outages and disturbances originate in the distribution system

4 Our Challenges Experts say the cascading blackout that put millions of Westerners in the dark last week was no surprise: Major power outages have more than doubled in the last decade.

5 The largest power failure in California history left nearly seven million people without power, affecting : San Diego Gas & Electric, Imperial Irrigation District Comisión Federal de Electricidad, Mexico Arizona Public Service Western Area Power Administration

6 Recent Blackout Highlights Nation's Rickety Power Grid Sep 16, 2011 In a July interview with ProPublica, FERC Chairman Jon Wellinghoff said that while the electric grid is reliable, it is degrading. "It's not getting better," he said. "It's getting worse."last week, for example, a mishap involving a single worker doing repairs on a power station near Yuma, Ariz., led to rolling blackouts over parts of Arizona, Southern California and Northern Mexico. Blackouts disrupt power to at least a third of U.S. homes each year, and studies show the number of outages is rising.

15 Classical OMS do not meet the demands of the Smart Grid. Hurricane Isabel was the costliest and deadliest hurricane in the 2003 Atlantic hurricane season. Winds reached: 165 mph (270 km/h) Damage: $3.6 billion (2003 USD) Dead: 16 direct, 35 indirect Pepco identified a problem with the link between the Energy Management System and the OMS in major events with an excessively high number of breaker lockouts and momentary interruptions. Specifically, when a breaker would trip in the Energy Management System, the information would be passed to the OMS, which would then perform the appropriate circuit analysis as if the breaker had locked out.

16 Classical OMS do not meet the demands of the Smart Grid environment. there was concern over the validity of the Outage Management System algorithm in the early stages of the restoration, and there was uncertainty about the stability of the Outage Management System based on problems experienced in the late August thunderstorms. Pepco identified this problem and broke the link between the two systems during the outage, creating the breaker lockout notification in the OMS manually.
