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
