Design of an Optimal Tip Speed Ratio Control MPPT Algorithm for Standalone WECS
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
This paper presents a design of an optimal tip speed ratio (OTSR) control maximum power point tracking (MPPT) algorithm for standalone wind energy conversion system. The system consists of a wind turbine, permanent magnet synchronous generator, diode bridge rectifier, boost converter and fuzzy logic controller (FLC). The wind turbine model details the mechanism of three bladed fixed pitch variable speed operation of the turbine. The generator model is established in the dq–synchronous rotating reference frame. Controlling the generator to achieve maximum power point can be done by diode bridge rectifier connected to a boost converter. Fuzzy logic controller is used to control the duty cycle of the boost converter. In order to verify the presented model simulations with MATLAB/Simulink software have been conducted. Simulation results prove the validity of the model. Moreover, the concept of the MPPT has been presented in terms of the adjustment of the generator rotor speed to maintain the optimal tip Speed ratio according to instantaneous wind speed.
