Item Design and Construction of an Arduino Based Solar Power Parameter Measuring System with Data Logger(Faculty of Engineering, University of Maiduguri, Maiduguri, Nigeria, 2020-06) Ibrahim, O; Babatunde, A. Y; Boluwatife, A. J; Afolayan, M. A; Ogunbiyi, O; Madugu, I. S; Zakariyya, O . SAccurate monitoring and measurement of solar photovoltaic panel parameters are important for solar power plant analysis to evaluate the performance and predict the future energy generation. There are always challenges of getting such data readily available due to huge amount of money to be spent on state of the art equipment or the purchase of reliable satellite weather data. This study aimed at the development of a cost-effective parameter-measuring system for a solar photovoltaic panel using Arduino microprocessor board. The systems measure five parameters, including voltage, current, light intensity, temperature, and pressure. The hardware circuit was designed to link different sensors with the Arduino board and the measured data were in turn were documented into a computer for further analysis. The accuracy of the constructed device was ascertained by comparing the measured parameters with that of conventional standard measuring instruments which shows good agreement. The measured parameters show that the output energy generation from solar photovoltaic panel largely depends on the solar irradiance and temperature.Item Development of A Direct Conductive Coupled Multi- Input Phase-Shifted Full-Bridge DC-DC Converter(School of Electrical Engineering, Faculty of Engineering, Universiti Teknologi Malaysia, Johor Bahru., 2020) Ibrahim, O; Yahaya, N. Z; Saad, N; Md Hassan, K. N; Otuoze, A. O; Afolayan, M. A; Madugu, I. S; Usman, A.MHybrid energy system is commonly employed in renewable energy systems to bridge the gap of non-availability of one power source with the others. In this work, a direct conductive electrical circuit connection topology for realizing multiple power source synchronization in the hybrid energy system is proposed. A three-input power sources integration scheme was realized via forward-conduction bidirectional blocking switch which serves input to the common power conversion stage of phase-shifted full-bridge DC-DC converter to boost the synchronized common bus voltage. An average current sharing controller is designed for the multiple parallel power sources to ensure equal load sharing when all the sources operates on the same and different voltage level. In this study, a 3-kW rating hybrid energy system was implemented in Simulink environment to investigate the multiple source integrator, the current sharing capability, and the common power conversion stage performance. The system ensured equal load sharing, allowed individual and simultaneous power transfer from the multiple sources to the load under the same and different operating supply voltage level.
