Artificial Bee Colony Based MPPT Technique for Solar PV System Under Partially Shaded Condition

Abstract

Energy recovery circuit plays significant role in PV string, during different irradiance value condition of PV modules. The BBCSC circuit is the combination of buck-boost converter and switched capacitor circuit; used to eliminate bypass diodes. The main objectives of BBCSC circuit are energy recovery from the photovoltaic modules under different irradiance value condition of PV modules and the voltage of the PV string is maintained on the level generated. In this paper, artificial bee colony (ABC) optimization technique is implemented with MPPT algorithm for solar modules string with boost converter and energy recovery circuit; to improve maximum output power and voltage values during PSC. The main limitation in the conventional method is to track exact MPP under partially shaded condition (PSC) is not satisfactory and Sometimes takes local maxima as global maxima. To overcome this, a new proposed artificial bee colony (ABC) algorithm MPPT is implemented. Comparative analysis has been carried out and verified between the above of state of art methods through simulation results. To valid and verify the effectiveness of the proposed BBCSC circuit, simulation results are presented in MATLAB/Simulink software.
