碩士 === 中原大學 === 電機工程研究所 === 105 === The solar modules will have a number of local maximum power point under partial shading conditions, such that the traditional maximum power point tracking (MPPT) methods will lead to some local maximum power points and reduce energy conversion efficiency. In order to avoid this problem, this thesis proposes a hybrid method by combining shuffled frog leaping algorithm (SFLA) and incremental conductance method (IncCond) for a multi-module DC solar power system. In this system, a master boost converter is used as a voltage regulator for the DC load, while the other slave boost converters perform the maximum power point tracking with Arduino control board. Finally, Matlab simulation and circuit implementation are carried out to verify the proposed hybrid method to achieve the global maximum power point tracking under partial shading conditions.
