Abstract
(EN)
A method for operating a renewable energy power plant comprising a plurality of renewable energy generators, a plurality of power dissipation systems and a battery storage system is provided. The method comprises steps of: monitoring the statuses of the power dissipation systems; performing a ramped active power recovery operation following a voltage deviation, and controlling the battery storage system during the ramped active power recovery operation to absorb power generated by the renewable energy generators in dependence on the monitored statuses of the power dissipation systems.
(FR)
L'invention concerne un procédé de fonctionnement d'une centrale électrique à énergie renouvelable comprenant une pluralité de générateurs d'énergie renouvelable, une pluralité de systèmes de dissipation d'énergie et un système de stockage de batterie. Le procédé comprend les étapes consistant : à surveiller les états des systèmes de dissipation d'énergie; à effectuer une opération de récupération d'énergie active en progression, suivant un écart de tension, et à commander le système de stockage de batterie pendant l'opération de récupération d'énergie active en progression pour absorber l'énergie produite par les générateurs d'énergie renouvelable en fonction des états surveillés des systèmes de dissipation d'énergie.
