Abstract

The purpose of the invention is to reduce the contribution of wind power installations to frequency errors on the grid, and preferably to contribute to the elimination of such errors. Thus, the method involves the use of PID control and / or control with hysteresis so as to regulate the active power injected into the grid, in view of the deviation between a measured grid frequency and the nominal grid frequency.

Description

technical field

[0001] The present invention relates to the field of wind energy systems and equipment, and in particular to a method for controlling the power generated by such systems and equipment to be supplied to a network or grid for power distribution. Background technique

[0002] Wind energy systems and devices include one or more wind generators or turbines arranged to generate electrical energy through wind-induced rotation. Electric energy produced by one or more of these generators (eg by several generators forming part of a so-called "wind farm" or constituting such a "wind farm") is supplied to a grid or network for energy distribution. Usually, a large number of electric generators are connected to the grid, and usually several electricity consumers are also connected to the grid.

[0003] In order to keep the voltage and frequency on the network substantially constant, it is important that the power input to the grid at each moment is exactly equal to the p...
