Abstract

This paper proposed a modified MPP-Locus method. Compared to the other MPPT methods, the MPP-Locus method is relatively simple to implemented into the PV system. Furthermore, this method does not require the designer's knowledge on the PV characteristic or the FLC rules. However, the conventional MPP-Locus method generally has some drawbacks, such as additional circuits required and less tracking accuracy for some cases. The proposed method can simplify improve the tracking accuracy, and does not increase the implementation complexity. Different scenarios are analyzed and simulated according to the irradiance change. Both simulation and experimental evaluation demonstrate the superior performance over other traditional MPPT methods.
