The paper by climbing method, the tip speed ratio method and other traditional maximum power point tracking control technology research and analysis, presents a new maximum power point tracking control technology ---- adaptive area method. This method can overcome the climbing method and incremental conductance method deficiencies, increasing the maximum power point tracking accuracy and response speed.
Finally, the use of matlab M-Function Editor, the first and the tip speed ratio for hill climbing method for modeling and simulation, to obtain its maximum power point tracking images. Then adaptive area method for modeling and simulation, adaptive area method to get the maximum power point tracking images. Climbing method and with the tip speed ratio based on the maximum power point tracking method simulation image contrast, response time and waveform from the stability of two aspects, reflecting the advantages of adaptive area method.
