EUGINE position on LFSM-O requirements defined at national level

The Commission regulation (EU) 2016/631 of 14 April 2016 establishing a network code on requirements for grid connection of generators defines a ‘limited frequency sensitive mode at overfrequency’ or ‘LFSM-O’ as “a power-generating module or HVDC system operating mode which will result in active power output reduction in response to a change in system frequency above a certain value”. LFSM-O is thus to be activated, when the system is in an emergency state of overfrequency and needs fast reduction of active power production.
