The Increasing Importance of Resiliency
RESILIENCY IS MORE THAN RELIABILITY
• Prevent and minimize damage• Enable continued operation • Rapidly return to normal
Resiliency - System improvements that prevent or reduce the impact on reliability and ability of the system to recover quickly after adverse events

Utilization of Grid Assets
Power Line Utilization = Maximum Demand / Rated Capacity
‣ 45%-55% due to contingency (NERC standards)
‣ Power losses increase withline utilization (4% vs. 20%)
‣ Transmission system is near peak loading for 40% of year
‣ Distribution system is near peak loading for 10% of year

Tight T&D Integration is Critical!
‣Plan T&D jointly– Incorporate local resources into broader area planning & analysis– Determine optimal location and sizing of grid assets– Account for supply and demand flexibility
‣Operate T&D jointly– Dispatch distributed generation in coordination with bulk generation– Coordinate flexible loads & DERs with bulk generation & storage– Mitigate the effects of extreme operating conditions

Technology Gaps – Tools Missing
• Develop multi-scale simulation tools accounting for increasing DER deployment and “edge” effects Simulation
• Enable optimal, cost-effective grid asset additions and upgrades Planning
• Conduct T&D market analysis and design Market Design
• Balance the system over larger areas and across T&DOperation
