Improving the Performance of MPPT on DC Grid PV Systems by Modified Incremental Conductance Algorithm

Mehmet Ali Özçelik and Ahmet Serdar Yılmaz
Abstract—The performance of photovoltaic (PV) system is affected by temperature, solar insolation, solar panel configuration and shading. In order to succeed maximum efficiency, PV arrays should operate at their maximum power point (MPP). Hence, the MPP tracking (MPPT) unit is implemented among the PV energy conversion system to obtain maximum power. In this study, incremental conductance (IC) algorithm, the most commonly used algorithm in MPPT systems for expectation-maximization, was analysed and an approach towards eliminating ripple problems, improving speed to obtain more power value, were maintained and duty cycle (Dk) value was obtained from IC algorithm under changing PV panel radiation conditions. In the end, it was evaluated alongside with MATLAB simulation results.

Index Terms—Photovoltaic (PV) cell, incremental conductance, maximum power point tracking (MPPT), boost DC/DC converter.
