This invention belongs to the field of wind power system control technology and discloses a wind power system control method and controller to cope with DoS network attacks. It constructs a novel adaptive event triggering mechanism algorithm with memory characteristics. When a hacker launches a DoS attack on an interconnected wind power system through the communication network, the controller signal is not updated, and the communication triggering mechanism does not generate a new trigger moment.

The combined effect of these two factors achieves system stability requirements while reducing data transmission and saving bandwidth. It has good adaptability and strong robustness and can be applied to various industrial applications.
