Frequency Containment Reserve. Disturbance (FCR-D) The purpose of FCR-D is to mitigate the impact of incidental disturbances, including the reference incident of the synchronous area. Upward FCR-D is activated when the system frequency drops below 49,90 Hz. The objective of FCR-D is to facilitate: • that the maximum frequency deviation does not exceed the maximum instantaneous frequency deviation (see section 3.4.1); and • continuous frequency stability outside the standard frequency range (see section 3.4.1).
