A central plant controller is configured to carry out a method of controlling an electric output of the wind power plant in the event of a transient low-voltage fault of the electric grid. The central plant controller is configured, after a fault stage in response to detection of a low-voltage fault during which the wind turbines ride through the grid fault, to control the wind power plant during a post-fault-support stage to provide only real power, or perform voltage control. The central plant controller is configured to resume control of the wind power plant according to the nominal-grid operation mode, which prevailed before the low-voltage fault, in a nominal-grid operation stage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Wind-power-plant control upon low-voltage grid faults","description":"A wind power plant connected to an electric grid.
