Fast Frequency Response
(FFR) Fast Frequency Response Virtual End Node for 2.0a where a Simple High Signal sheds load based on a Modbus Meter providing Frequency Data when Under Frequency is detected. Conversely the Utility may set up the VTN to a send Moderate Signal which would consume load based on an Over Frequency.
GRIDlink can be configured to invoke custom Control Logic to Shed or Consume Loads based on Special 2.0b Signals.
