Maximum Power Point Tracking of PV Module Based on New Explicit I-V Relation

This paper proposes an algorithm for maximum power point tracking of a photovoltaic (PV) module using an explicit current-voltage (I- V) relation. The model considers a variation in I with linear and power dependency on V. The proposed model is validated for a 160 W polycrystalline silicon module connected to a resistive load through a boost converter under different environmental conditions in MATLAB and experimentally. The performance of the proposed algorithm is compared with an existing model based algorithm or P&O and also analyzed for tolerance and aging effect. The accuracy of the proposed algorithm is better than the existing algorithm.
