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

Microgrid technologies – grid resiliency

1. Grid-connected and off-grid operations2. Interconnection of renewable generation3. Islanded operations during storm response

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


State of the grid – aging transformers, 300M wooden poles

• Many T&D assets arepast their expected lifeand are at risk forcatastrophic failure

• Utilities must maintainor improve reliabilitywhile controlling bothcapital and operationalexpenses


Uses advanced analytics to improve overall asset performance and system reliability. It balances:

Operational performanceFinancial performance Business Risk

Monitors assets at the ‘fleet’ or “substation” level by Risk of Failure (ROF) and Importance.

Asset Health Management

Reduce risk of critical assetfailure

Deploy capital most effectively

Optimize O&M spend whereit’s needed most

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
