Resiliency in the US Capital RegionHardening the Grid: One Year after Sandy
G. RACKLIFFE, ABB

Superstorm Sandy• 8.5 million people without power across 21 states
– the highest outage total for an extreme weatherevent in history
• $65 billion in damage making it the 2nd mostcostly hurricane to hit the US after Katrina
• The superstorm followed three major extremeevents on the East Coast:
1. Hurricane Irene in August 2011 interruptedpower for 4 million people along the eastcoast with $15.6 billion in damage
2. A Halloween nor’easter knocked out powerfor more than 3 million people in the Mid-Atlanta and Northeast
3. Outages from a Derecho in June 2012affected more than 4 million people in theMidwest and Mid-Atlantic

Severe weather events
• Severe weather events arecausing widespread outages
• Regulators and policy makersare increasing penalties
• Customers are dissatisfiedand are investing indistributed generation

Traditional definition of resiliency
“The ability to become strong, healthy, or successful again after something bad happens.”
Webster

No one-size-fits-all solution to grid security, hardening and resilience
New definition of resiliency: The ability of people, networks and systems to anticipate events, absorb disturbances and adapt to evolving conditions • OT/IT worlds are converging; requires a holistic solution set
• Synthesis of grid data key to building system wide common operating picture for strategic scenarioanalysis and foresight planning

Self healing grid strategies• Fault Detection, Isolation, and Restoration (FDIR)
– Coordinated control between groups ofreclosers, load break switches, and highvoltage circuit breakers across thedistribution grid
– Determines fault locations and preparesswitch orders to isolate faults andreconfigure the grid to immediately restoreas many customers as possible usingdistribution SCADA
• Benefits– Maximum improvement in SAIDI and CAIDI
scores– Takes advantage of the load profile
forecasting applications and uses the loadflow to verify solutions
– Allows utilities to take a proactive approachto grid management
– Highest level of worker safety

Benefits of outage lifecycle management
Ensure compliance with regulatory requirements
Restore power faster, more safely and efficiently
Better real-time visibility for smarter, faster decisions
Capture expertise into mobile technology for safer, more efficient work
Better communication with customers, regulators and media
Better processes = quicker outage restoration = happier stakeholders

Minimal space requirement
Compact, unobtrusive design ideal forkey urban electrical infrastructure
Gas insulated substations are easilyelevated. Due to smaller size, can beplaced inside or covered.
Improving resiliency – physical design solutions
Gas insulated switchgear Underground cables
No overhead lines
Buried cables are more difficult totarget
Greater resiliency to weather
Same power can be transmitted

Grid Resiliency – Supported by Situational Awareness
• Synthesis of grid data key to building system wide common operatingpicture for strategic scenario analysis and foresight planning
• Automatic control of recovery following a disturbance is paramountto efficient decision making based on a multitude of catastrophescenarios
