Wind energy source has a complex control situation because of dependence of its torque and output power on wind speed and its fluctuations. Based on this, in order to improve its control condition and dynamic efficiency, when connecting to the microgrid, ultra-capacitor which has a fast charging and discharging speed is used. Furthermore, the maximum energy derived from wind turbine and ultra-capacitor by the microgrid is of high importance which must be considered besides decreasing output power fluctuations. In this paper, for increasing the harvested energy, the Wind Speed Forecasting (WSF) model is used. So, the control method is applied by using WSF. In the proposed method, the gained energy is more than the lost energy. In fact, we increased harvested energy using a predictive control method. The considered predictive control is applied to the induction generator rotational speed variations. The …
