This article introduces a simple and reliable interleaved boost converter that interfacing photovoltaic (PV) generator. The PV generator is driven at Maximum Power Point (MPPT) via Perturb and Observe (P&O) algorithm. A simple control strategy based on a Proportional-Integral (PI) controller is advised to control the boost chopper and the PV generator. PI improves the dynamic performance, reduce the steady-state error, and increase the robustness against nonlinearities and parameter variations. The controller parameters are optimally tuned using the bio-inspired Goose Optimization Algorithm (GOA), which exhibits fast convergence and high efficiency in complex optimization tasks. The simulation studies corroborate the proposed ability of the system to maintain constant DC link voltage, accurately track current references, and achieve high power conversion efficiency under dynamic operating conditions.
