A control system and control method of a wind farm allows taking into account dynamic variations in the possibilities of reactive power generation of each wind turbine with respect to maximum reactive power generation capacities. The system is configured to receive from at least one first wind turbine of the wind turbines of the wind farm a maximum reactive power limit desired lower than a minimum reactive power capacity required. The system is configured to calculate the individual reactive power setpoints for each of the at least two wind turbines of the wind farm such that the individual reactive power setpoint for the at least one first wind turbine of the wind farm does not exceed the maximum reactive power limit desired.
