Utility
Control of a wind power plant
23 Aug 22
The present invention relates to a method for controlling a wind power plant, WPP, comprising a plurality of wind turbine generators, WTGs, connected to an electrical grid, the method comprising: setting a plant power reference (Ptotal) according to an electrical value of the electrical grid; determining an inertia delta power reference (IRdeltaP) required for the WPP to meet a power demand in response to a change in the electrical value; adding the inertia delta power reference and the plant power reference (Ptotal) to form a power reference (Ptotalref); deriving an overboost reference (PrefOB) as the difference between the power reference (Ptotalref) and an available power value; dispatching the power reference (Ptotalref) to each wind turbine generator; dispatching the overboost reference (PrefOB) to each wind turbine generator.
