Maximum Power Point Tracking Algorithm with Turn Round Measurement and Curve Fitting Method for Solar Generation System
Authors: , , ,
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.
