Abstract

This thesis describes the system required for a solar electric boat power system with energy storage and a DC gas generator for sailing the boat at 10km/h with 20people. Details of existing diesel engine-driven boats in a river in Bangladesh were collected for the system design. Sizing assessment, sensitivity analysis, and optimization of required power are performed in HOMER. The system’s equipment is modeled in MATLAB Simulink platform and simulated to know the dynamic performance of system components. An Arduino-based basic control system also was proposed for the solar boat. The proposed system was simulated in Tinkercad.com web-based software to check the live functionality of the designed control system. Power system instruments were proposed, including solar PV panel, PMDC motor and driver, generator, lead-acid battery, circuit breaker, busbar, and a programmable display device to measure battery voltage and capacity and display data. Additionally, navigation instruments were proposed for measuring water depth, boat speed, and water temperature and display the values on a monitor. The projected payback period was calculated for the recommended solar boat. PV/diesel/battery hybrid power system is compared with PV/battery and the traditional diesel-only power system in this research. Economic analysis indicates that the proposed solar boat design is the best option for rivers in Bangladesh.
