The steady increase in fossil fuel costs and the lack of dependable grid access in many coastal and inland fishing regions have created a strong demand for alternative energy sources. Renewable energy, particularly solar power, offers a practical solution for operating essential equipment in remote fisheries. This study examines the design and performance of a solar photovoltaic (PV) powered DC pump system integrated with a Maximum Power Point Tracking (MPPT) control strategy to enhance energy utilization efficiency.
The proposed system is intended to support key fisheries activities such as water pumping, aeration, and circulation, which are vital for maintaining aquatic environments and handling operations. The overall configuration includes a PV array, a DC–DC boost converter, an MPPT controller, and a DC motor-driven pump. To ensure optimal power extraction from the PV array under changing weather conditions, the Incremental Conductance (INC) algorithm is employed. This method continuously evaluates voltage and current variations to identify and maintain operation at the maximum power point, even when solar irradiance and temperature fluctuate.
The complete system is modeled and simulated using MATLAB/Simulink to assess its dynamic behavior and steady-state performance. Simulation results indicate that the MPPT-controlled system achieves faster tracking of the maximum power point with minimal oscillations compared to conventional control techniques. The boost converter effectively regulates the output voltage, supplying stable and sufficient power to the DC pump motor. As a result, the pump operates reliably under varying environmental conditions, ensuring uninterrupted performance for fisheries-related tasks.
The findings demonstrate that a solar PV system equipped with an MPPT-based control scheme provides an efficient, environmentally friendly, and economically viable solution for small-scale fisheries. By reducing reliance on diesel or grid electricity, the system lowers operational expenses and supports sustainable practices in isolated and off-grid locations. Overall, the proposed configuration shows strong potential for practical deployment in fisheries where clean and dependable energy is essential.
