ELECTRICITY GENERATION SYSTEM COMPRISING A WATER TURBINE WITH IMPROVED DYNAMIC RESPONSE

An energy production system including a hydraulic turbine system having undesirable electrical power output setpoints and identified safe electrical power output setpoints, an energy storage system, a connection connected to the energy storage system and to an electric machine of the hydraulic turbine system, and further connected to an AC power network, a device for determining the state of charge, a control circuit controlling a transfer of electrical power between the connection and the energy storage system, configured to receive an electrical power setpoint value (Reps) and configured to determine that this received electrical power setpoint value belongs to the undesirable electrical power output setpoint values to generate an electrical power transfer setpoint value (Epts), and an actual electrical power output setpoint value (Aepos) belonging to the safe electrical power output setpoint values, satisfying the relationship Reps=Epts+Aepos.
