Abstract

Penelitian ini menyajikan pengembangan sistem hybrid charge controller yang mengintegrasikan modul solar panel (PV) dan generator magnet permanen (PMG) yang digerakkan oleh hydrokinetic turbine untuk aplikasi kapal penangkap ikan. Sistem dimodelkan dalam MATLAB Simulink dengan menggunakan Simscape Electrical dan Simscape Battery, di mana model fisik diimplementasikan melalui MATLAB Function Block dan algoritma kendali diimplementasikan melalui integrated code interface. Maximum Power Point Tracking (MPPT) menggunakan algoritma Perturb & Observe (P&O) untuk modul PV dan Incremental Conductance (IC) untuk PMG, yang dipilih berdasarkan karakteristik dinamis masing-masing sumber energi. Sistem ini terdiri atas empat subsistem, yaitu dua subsistem pembangkit daya (PV dan PMG), satu subsistem baterai yang terdiri atas 16 modul baterai LiFePO₄ 120 Ah yang dirangkai dengan konfigurasi 16s, serta satu subsistem utama modul MPPT yang mengintegrasikan algoritma kendali dengan rangkaian PV dan PMG ke dalam satu sistem pengisian daya hibrida. Array PV dikonfigurasikan sebagai 2P4S dengan kapasitas terukur 1600 Wp pada tegangan 72 VDC, sedangkan PMG memiliki daya terukur 300 W pada tegangan 24 VDC. Hasil simulasi menunjukkan bahwa sistem berhasil melakukan mode pengisian baik secara stand alone maupun hibrida dengan mempertahankan keluaran listrik yang stabil. Pengendali pengisian otomatis mengatur proses pengisian, memulai dan menghentikan operasi ketika state of charge yang telah ditentukan tercapai. Algoritma IC diimplementasikan pada PMG karena kemampuannya dalam memberikan transisi yang stabil di bawah kondisi operasi yang sering berubah, sedangkan P&O digunakan untuk modul PV karena kondisi yang lebih stabil dan kemampuannya dalam mempertahankan tegangan tinggi meskipun pada tingkat irradiansi rendah. Kemampuan energy harvesting dievaluasi selama satu hari operasi penangkapan ikan yang berlangsung selama 8 jam muali dari pukul 08.00–16.00 dengan jarak tempuh 6 mil laut dan 4 mil laut pada malam hari. Hasil menunjukkan bahwa sistem menghasilkan energi rata-rata sebesar 9.558 Wh, melampaui konsumsi beban sebesar 7.747,15 Wh, sehingga mengonfirmasi bahwa sistem ini memadai untuk aplikasi yang dituju.

This research presents the development of a hybrid battery charging control system integrating a photovoltaic (PV) array and a hydrokinetic turbine driven permanent magnet generator (PMG) for fishing vessel applications. The system is modelled in MATLAB Simulink using the Simscape Electrical and Simscape Battery libraries, with the physical plant implemented with a MATLAB Function block and the control algorithms implemented through an integrated code interface. The maximum power point tracking (MPPT) strategy employs the Perturb & Observe (P&O) algorithm for the PV module and Incremental Conductance (IC) for the PMG, selected based on the respective dynamic characteristics of each source. The system comprises four subsystems, two power generation subsystems, PV and PMG, a battery subsystem consisting of sixteen series-connected 120 Ah LiFePO4 battery packs configured in 16S, and a main MPPT module subsystem that integrates the control algorithms with the PV and PMG circuits into a unified hybrid charging system. The PV array is configured as 2P4S with a rated capacity of 1600 Wp at 72 VDC, while the PMG is rated at 300 W at 24 VDC.
Simulation results demonstrate that the system successfully performs both stand alone and hybrid charging modes while maintaining stable electrical output. An automatic charge controller regulates the charging process, initiating and terminating operation upon reaching the predefined state of charge. The IC algorithm is implemented for the PMG due to its ability to provide smooth transitions under frequently changing operating conditions, whereas P&O is employed for the PV module, where less dynamic conditions happen and high voltage must be sustained at low irradiance levels. The energy harvesting capability was evaluated over a typical one day fishing operation spanning 8 hours from 08:00–16:00 with a range of 6 nautical miles for day operation and 4 nautical miles for night operation. Results indicate that the system generates an average of 9558 Wh of energy, exceeding the load consumption of 7747.15 Wh, thereby confirming its adequacy for the intended application.
