Abstract

This research work focuses on a stand-alone low power wind energy conversion system (WECS) where the main objective is to obtain the most energy from the wind and deliver it efficiently to the electrical load. The strategy to deal with this problem is to design a sliding mode controller applied with a maximum power point tracking algorithm (MPPT). In this dcbased micro-grid, the dc output voltage is kept nearly constant by the battery bank; therefore, it is not necessary to regulate this voltage. As the objective is to maximize the WECS power production, the specially designed sliding mode controller constantly adjusts the boost converter inductor current to modify its input voltage, which is the rectified wind generator ac voltage, until the system power reaches the maximum set by the MPPT.
