Concerns About BES
• NERC began pursuing the issue following events in Germany.• High-penetration parts of the US began to see stability issues
(CA & HI).• NERC formed a Task Force to study the problem.• A Key Report was released December 2013:
Performance of Variable Resources During and After System Disturbance

Good News!
• Can help stabilize Voltage on Distribution circuits.• Reduce wear on Voltage Regulators & LTCs.• Can mitigate flicker and other voltage fluctuations.• May reduce the need for reconductoring to offset
effects of voltage swings.

Caution!Law of Unintended Consequences!
• Evaluate circuit & DER carefully to choose method and settings.
• As other DERs are added, may need to reevaluate original method & settings.
• Load increases, decreases or reconfiguration of circuit can all come into play.
• Any of these methods may lead to power quality issues if not closely managed.

Categories A and BNormal Operating Performance
• Cat A Meets VAR & Control requirements for all DER systems presently in use.
• Cat B Enhanced requirements which can benefit the power system, but which some DER systems may not meet.
