ENHANCEMENT OF MPPT MODULE FOR PARTIAL SHADING PHOTOVOLTAIC SYSTEM UNDER UNIFORM IRRADIANCE CONDITIONS

Maximum Power Point Tracking (MPPT) algorithms play a critical role in maximizing the output power of solar panels. Different MPPT techniques are evaluated based on several criteria, such as tracking speed, simplicity, and accuracy with changes irradiance ambient temperature. Under partial shading conditions (PSCs), conventional fail to track global maximum points (GMPP). This paper aims present an automatic accurate method fix complexity determining lookup table data fast process under uniform (UICs) PSCs. The proposed runs photovoltaic (PV) module all potential It automatically calculates perfect voltage reference (Vref) for PV system cases. Vref is collected array, sent into two-dimensional table, used controlling boost converter. Simulation results verify effectiveness method. In addition, comparison was also made perturb observe (P&O) UICs, takes less time than P&O algorithm reach MPP. difference between them ?t = 0.133 sec 0.04 first scanning at t 0 sudden change 1.5 sec, respectively. As PSCs, reached GMPP during pattern 104 (first peak) without any loss, while able but losses 2729.97 watts. ABSTRAK: Algoritma Penjejakan Titik Kuasa Maksimum memainkan peranan penting dalam memaksimumkan kuasa keluaran panel solar. Teknik yang berbeza dinilai berdasarkan beberapa kriteria seperti kelajuan pengesanan, kesederhanaan, dan ketepatan dengan perubahan sinaran suria suhu ambien. Di bawah keadaan teduhan separa (PSC), teknik konvensional gagal menjejak titik maksimum Kajian ini bertujuan bagi membentangkan kaedah automatik tepat membetulkan kesusahan menentukan carian berjadual secara tepat, pantas di seragam (UIC) PSC. Kaedah dicadangkan menjalankan modul fotovoltaik semua potensi mengira rujukan voltan sempurna kes berpotensi sebarang jenis sistem PV. dikumpul tata susunan, dihantar ke jadual dua dimensi, digunakan mengawal penukar rangsangan. Keputusan simulasi mengesahkan keberkesanan dicadangkan. Perbandingan juga dibuat perhati ganggu (P&O). UIC, mengambil masa lebih singkat berbanding algoritma mencapai Perbezaan antara keduanya adalah masing-masing, saat proses pengimbasan pertama iaitu pada mendadak saat. Bagi PSC, semasa corak (puncak pertama) tanpa kehilangan manakala dapat mengesan tetapi pengurangan sebanyak watt.
