Frequency containment reserves (FCR products)
Frequency Containment Reserve for Normal Operation (FCR-N) and Frequency Containment Reserve for Disturbances (FCR-D) are active power reserves that are automatically controlled based on the frequency deviation. Their purpose is to contain the frequency during normal operation and disturbances. FCR-N aims to keep the frequency within the standard frequency range of 49,9 Hz to 50,1 Hz. FCR-D aims to limit the frequency deviation to 49,5 Hz or 50,5 Hz when the frequency goes outside the standard range.
FCR-N is a symmetrical product that must be capable of both up- and downregulation. Upregulation means increasing power production or decreasing consumption. Downregulation means decreasing power production or increasing consumption. FCR-D is divided in separate up- and downregulation products.
