Embodiment
[0084] In the following, the present invention takes an actual wind farm in China as an example to illustrate the application effect of the present invention in detail. The wind farm contains 33 double-fed wind turbines with a rated power of 1.5MW, and is connected to a properly modified IEEE-9 node power system. The measured data on May 18, 2019 was selected as the test data, including the measured wind speed of each wind turbine inside the wind farm (one measurement point every 5 minutes, a total of 288 measurement points) and the real-time active output of each wind turbine. .
[0085] figure 1 The implementation process of the content of the present invention is shown. Based on the aggregation evaluation model of wind farm reactive power control capability and the online monitoring model of wind farm reactive power control capability, according to the gradually accumulated relevant operation data, the evaluation error and evaluation consumption in the daily operation sce...
