Improvement of power forecasting model for wind power generation
摘要
Abstract
In order to improve the generation power and application efficiency of wind generator,the power prediction for wind power generation is needed to achieve optimal control of the generator. A fuzzy PID based power prediction model of wind power generation is proposed in this paper. The circuit model of wind power generator is built,and then the controller model for wind power generator is designed by taking the parameters of output goal current,output power,excitation current and rotor cur-rent of the wind power generator as the constraint parameter model. In the optimized control model,the fuzzy PID control objec-tive function for generation power prediction is established according to Kirchhoff voltage loop model,and its optimal solution is obtained to achieve effective generation power prediction. The experimental results show that the method has high precision and good convergence for power forecasting of the wind power generation,and can improve the output efficiency of wind power genera-tor effectively.关键词
