Abstract
Solar photovoltaic system is one of the growing renewable energy sources in the energy market. The performance of the PV system is mainly affected by the partial shading which is inevitable. It creates mismatch losses between the PV rows that reduce the power generation. Many research works proposed solutions like Maximum Power Point Tracking (MPPT) and static & dynamic reconfiguration methods. These methods can enhance the power conversion rate of the PV system. However, this power conversion rate can be enhanced by the proposed mismatch loss mitigation algorithm. A current compensation converter has been developed to operate the PV system with even current generating rows. The PV row currents have been measured by using the current sensor and fed to the controller. The controller performs the algorithm and generates the triggering signals to the DIDO converter and it operates the PV rows with even current generation. The performance of the proposed system has been simulated under five kinds of shading patterns using the MATLAB/Simulink® and the corresponding PV curves were plotted. This work is also validated using the 200Watts PV system, which is constructed with the four polycrystalline PV modules as a 2 × 2 PV array. The performance of the proposed system with the corresponding results and waveforms are presented in this work.
