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.

In large PV plants, a number of inverters are linked together at grid-side to generate more power. However, as the inverter modules increases, ground current problem worsens. This can result in fault, and cause failed disconnected from grid. this paper, solutions, including hardware software, proposed suppress current. The solution is connect filter capacitors back DC-bus, directing rather than grid reduce Additionally, software carrier phase shifting frequency shifting, proposed. for be cancelled each other, which alleviate problem. system architecture presented first. concept connecting neutral point DC-bus midpoint explained. zero-sequence mathematical model then built. Moreover, effect voltages DC/AC converter on investigated. Then, control presented, followed by an explanation how obtain three-phase output voltage components inverters. Two detailed. Finally, experiment conducted verify theory.

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
