Abstract: The invention lies in the field of current stabilisation in a power generation system comprising a plurality of elementary power groups connected in parallel. It relates to a control system for regulating the elementary power groups. According to the invention, the control system comprises a global current control system (510) and a plurality of local current control systems each associated with an elementary power source of the power generation system. The global current control system (510) comprises: ▪a divider (511) arranged to deliver a fixed current set point In_fix, ▪correction unit (512) arranged to deliver a variable current set point In_var and to take either a steady state or a transitory state, the variable current set point In_var being determined as a function of a correction signal Scorr in the transitory state, ▪an adder (513) arranged to deliver a global current set point In_glob as the sum of the fixed current set point In_fix and the variable current set point In_var, and ▪a scenario management unit (514) arranged to detect when the state of at least one elementary power source (2201-220N) switches from an OFF-state to an ON-state, or vice versa, to determine the correction signal Scorr and to trigger the transitory state of the correction unit for a predetermined transitory period τtrans when a change of state is detected.
