1. A wind farm control strategy method, comprising:
acquiring incoming flow wind data of a target wind farm, a restriction relationship between wind turbines in the target wind farm and current working condition data of the wind turbines in the target wind farm, wherein the restriction relationship between the wind turbines in the target wind farm is a wake influence relationship between the wind turbines;
inputting the incoming flow wind data, the restriction relationship and the current working condition data into a pre-trained working condition prediction model to obtain target working condition data corresponding to a target generation power of the target wind farm, wherein the target generation power is a maximum generation power of the target wind farm; and
controlling an operation of the wind turbines in the target wind farm based on the target working condition data;
wherein, a training method of the working condition prediction model comprises the following steps of:
acquiring sample incoming flow wind data, initial working condition data of wind turbines in a reference wind farm, sample working condition data corresponding to a sample generation power of the reference wind farm and a restriction relationship between the wind turbines in the reference wind farm, wherein the restriction relationship between the wind turbines in the reference wind farm is a wake influence relationship among the wind turbines in the reference wind farm; and
training a preset neural network based on the sample incoming flow wind data, the initial working condition data of the wind turbines in the reference wind farm, the sample working condition data corresponding to the sample generation power and the restriction relationship between the wind turbines in the reference wind farm to obtain the working condition prediction model, wherein the sample generation power is a maximum generation power of the reference wind farm, and the sample generation power comprises the target generation power; and
the operation of acquiring the sample working condition data corresponding to the sample generation power of the reference wind farm, comprises:
simulating the sample incoming flow wind data and the initial working condition data of the wind turbines in the reference wind farm by using a preset wind farm simulation model to obtain generation power of the wind turbines in the reference wind farm; and
adjusting the initial working condition data of the wind turbines in the reference wind f am according to the sample generation power and a sum of the generation power of the wind turbines in the reference wind farm to obtain the sample working condition data corresponding to the sample generation power of the reference wind farm.
