14 Backup Power: Provide backup power after disconnecting from grid The DER system, including energy storage and electric vehicles, has the ability to provide real when the site is disconnected from grid power. The reason is for providing backup power to the facility and possibly black start capabilities. Autonomous Local: Monitor voltage, frequency, and connected load O Decision by the DER 15 Imitate capacitor bank triggers: Provide reactive power through autonomous responses to weather, current, or time-of-day Similar to capacitor banks on distribution circuits, the DER system implements temperature-var curves that define the reactive power for different ambient temperatures, similar to use of feeder capacitors for improving the voltage profile.
