Outline of Final Research Achievements

In this research, for the purpose of improving efficiency in maximum power control of small wind power generator, we proposed a control method using wind speed prediction value and examined its usefulness. In order to obtain good control performance, it is necessary to improve prediction accuracy of wind speed / wind direction, we investigated about various wind speed / wind direction prediction models (complex-valued neural network, support vector machine, 1 dimensional convolution neural network) based on statistical method. In addition, a simulation model of a maximum power control system using a chopper circuit was constructed and high efficiency improvement based on the wind speed prediction value was examined. However, it is necessary to further improve the wind speed prediction accuracy because the dependency of the wind speed prediction value is high.
