Introduction Photovoltaic systems offer immense potential as a future energy source, yet maximizing their efficiency presents challenges, notably in achieving optimal voltage due to nonlinear behavior. Operating current and fluctuations, driven by temperature radiation changes, significantly impact power output. Traditional Maximum Power Point Tracking (MPPT) methods struggle adapt accurately these dynamic environmental conditions. While Artificial Intelligence (AI) optimization techniques show promise, implementation complexity longer attainment times for (MPP) hinder widespread adoption. Method This paper proposes hybrid MPPT technique that integrates the Pelican Optimization algorithm (POA) with Perturb Observe (P&O) grid-connected photovoltaic system (PV). The proposed consists of two loops: PO reference point setting loop (inner loop) POA fine-tuning (outer)loop. combination inner outer loops minimizes oscillations adjusting perturbation direction enhancing convergence speed MPPT. Results Discussion To validate efficacy different conditions, comprehensive comparison is conducted between pelican perturb observe (HPPO) other algorithms. has optimized PV grid outputs an 99%, best tracking speed, total harmonic distortion (THD) all conditions below 5% agree IEEE 519 standards.

Among the most sustainable forms of energy, solar energy delivers clean, dependable, and limitless power. However, PV arrays experience uneven irradiance as a result partial shadowing situations, which causes several peaks in their characteristics. Reconfiguration alleviates mismatch loss enhances power generation shading. Compared to normal conditions, this shade scenario results less generation. In proposed work, 4 × array is exposed different shading conditions identify optimal arrangement, various parameters like losses, fill factors are found compared with existing methods. The comparisons examines revealed that reconfigured deliver improved maximum global values. This reconfiguration technique an average output by 18.37% thereby increasing 293.2 kWh even under when other conventional configuration

ABSTRACT Urgent demand for renewable energy coupled with rapid urbanization and limited space in urban environments requires innovative photovoltaic (PV) module designs that can efficiently address significant power loss under shading. This research proposes small‐area high‐voltage (SAHiV) modules equipped cross‐tied bypass diodes at the level. SAHiV are pseudo‐high‐voltage, low‐current principle improve efficiency reliability of PV various shading conditions. study involves extensive simulations experimental validation to compare performance conventional, shingled, influence diode connection configurations generally used array scale. In particular, five intensively considered total (TCT) modifications level arrays determine optimal configuration. addition, we tested output using methods maximum point tracking (MPPT) fixed voltage standard test conditions (V STC ). The results show substantially outperform conventional shingled maintaining high nearly ideal some TCT connections. These findings emphasize importance optimizing connections system performance, safety, lifetime offer a practical solution partial
