<![CDATA[This study aims to analyze the performance of the Incremental Conductance Maximum Power Point Tracking (MPPT) method on a photovoltaic (PV) system operated under partial shading conditions using a double boost converter topology. This study is motivated by the limitations of the conventional MPPT method in accurately tracking the Global Maximum Power Point (GMPP) under multi-peak power conditions due to partial shading, as well as the limited studies that integrate the Incremental Conductance method with a double boost converter. The PV system studied consists of four modules configured in series-parallel and connected by a double boost converter. The converter duty cycle is controlled using the Incremental Conductance algorithm designed to detect changes in conductance with voltage. Performance evaluation wascarried out through simulations using the PSIM software by applying three different partial shading patterns to test the GMPP tracking capability and system response. The simulation results show that the system can extract 185.40 W of input power and produce 180.66 W of output power in the first shading pattern. In the second and third patterns, the input power is 184.77 W and 183.52 W, respectively, with output power of 180.05 W and 178.76 W. The MPPT efficiency obtained is in the range of 97.40%–97.44% with a system response time of 0.1 ms. These results indicate an increase in the tracking capability compared with conventional approaches that generally experience oscillations in multi-peak conditions. The novelty of this research lies in the integration of the Incremental Conductance method with a double boost converter topology to improve the accuracy of GMPP tracking in partial shading conditions. In addition, this research demonstrates that the proposed approach is capable of producing high efficiency and fast response; therefore, it has the potential to be applied to real PV systems to improve reliability and energy efficiency in non-uniform environmental conditions.]]>
