Study of MPPT Simulation Based on Power Prediction Method and Variable Step Incremental Conductance Method

Abstract:

Traditional incremental conductance method is one of the most widely used methods of MPPT in solar photovoltaic system. But oscillation and misjudgment also exist, which have a great impact on the efficiency and stability of solar system. This thesis proposes a new MPPT algorithm, that is, to combine power prediction method with incremental conductance method organically; simultaneously to apply variable step theory to reduce oscillation and avoid misjudgment. After the simulation in MATLAB7, it proved to be feasible by comparing with traditional incremental conductance.
