Abstract: Aiming at the complexity of offshore wind power prediction, an offshore wind power prediction model is established with the power generation prediction accuracy as the main optimization objective, and multi-dimensional meteorological data input methods such as wind speed, wind direction, air density, etc. At the same time, on the basis of constructing the XG-Boost algorithm, a parameter-seeking optimization mechanism that introduces the simulated annealing algorithm is proposed to avoid the algorithm from falling into the local optimal solution. The algorithm is applied to enterprise data and compared with the other three algorithms, and the results show that the improved SA-XG-Boost algorithm can effectively improve the prediction accuracy and provide reliable support for the stable operation of offshore wind power enterprises.
