Comparative analysis of the MPPT methods employed in the PV system, involving incremental conductance control and sliding mode control

The objective of this research paper is to investigate diverse strategies for achieving optimal maximum power point tracking (MPPT) in photovoltaic (PV) systems. The research delves into the evaluation and comparison of two distinct MPPT techniques: incremental conductance (InC) and sliding mode control (SMC). A DC/DC boost converter is employed between the PV system and the load to facilitate the efficient transfer of the maximum available power. Conventional MPPT methods, such as InC, have shown limitations in detecting and accurately tracking the high point, resulting in a notable power loss. To address this issue, a proposed solution is the utilization of sliding mode control. This method has a number of benefits, including as accurate reference tracking, low distortion in current output, and resilience to changes in parameters. However, a challenge with this technique is the occurrence of pronounced oscillations during transitional periods. The results of simulation confirm that the outcomes achieved through The MPPT SMC outperforms the MPPT INC in relation to tracking the MPP, leading to reduced power losses. This suggests an improvement in the overall efficiency of the system. Additionally, the voltage and current are higher than in MPPT with InC. However, oscillations are more noticeable when using MPPT with SMC.
