Recently, Maximum Power Point Tracking (MPPT) algorithms plays an important factor in optimizing the output power obtained from WECS. Because of that, the implementation of a robust and effective MPPT algorithm in the power converter becomes necessary to keep the output power at its maximum value irrespective of any sudden change in either wind speed or load. This paper presents a novel MPPT algorithm based on optimization of converter duty cycle values. The main idea is to build a mathematical model which relates the optimal duty cycle according to wind speeds. This model has been built based on simulations of a standalone low-cost WECS consisting of wind turbine, permanent magnet synchronous generator (PMSG), uncontrolled rectifier, DC/DC boostconverter and constant load. The WECS have been simulated based on variable wind speed. The duty cycle values have been selected while monitoring and recording the output power. Then, the model has been built based on the optimal duty cycle which ensures the successful achievement of the MPP operation at specific wind speed. The results obtained have shown improved and acceptable performance of low-cost WECS in terms of MPP operation achievement and tracking time.
