Abstract
(EN)
A hybrid power system (100) comprising a wind turbine (102) having a wind turbine generator and a power converter, and one or more DC power sources (104). The hybrid power system is configured to prioritize active power output over reactive power capability when the wind turbine is not operating, and is further configured to prioritize reactive power capability over active power output when the wind turbine is operating and wind speed is above a predetermined threshold. Methods for operating a hybrid power system are also provided.
(FR)
La présente invention concerne un réseau électrique hybride (100) comprenant une éolienne (102) ayant un générateur éolien et un convertisseur de courant, et une ou plusieurs sources d'alimentation en courant continu (104). Le réseau électrique hybride est configuré pour hiérarchiser la puissance de sortie active sur la capacité de puissance réactive lorsque l'éolienne n'est pas en fonctionnement, et est en outre configuré pour donner la priorité à la capacité de puissance réactive par rapport à la puissance de sortie active lorsque l'éolienne est en fonctionnement et la vitesse du vent est supérieure à un seuil prédéterminé. L'invention concerne également des procédés de fonctionnement d'un réseau électrique hybride.
