Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of WSEAS Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

ABSTRACT: A novel maximum power point tracking (MPPT) algorithm is proposed in this paper. The novel algorithm adopted a round back measurement which makes it easy to avoid misjudge when the irradition varies rapidly, especially comparison to traditional MPPT strategy. What’s more, round back measurement makes it possible to imitate PV array’s P-U curve with mathematical method which makes it possible to reduce the oscillation near PV’s maximum power point (MPP). Lagrange Interpolation Formula is used in this paper to fit PV’s P-U curve and a simulation with Matlab/Simulink tool to verify the proposed has been done. The result reveals proposed MPPT algorithm is more accuracy in irradiation variation situation and less oscillation near the MPP. These features make the algorithm a good idea in high-power solar generation system.
