Thesis / Project Title: Development of Battery/Supercapacitor Hybrid Energy Storage Scheme for Grid Connected Solar PV Source

The research has expressly developed a hybridized energy scheme for a solar PV source that is integrated to the grid. The main objective of the study was to achieve a continuous power flow from the solar PV generated with the backup storage from lead acid battery (PbA) and the super capacitor (SC). This research objective was met by first obtaining the design parameters and then modelling the three power sources namely; solar PV, battery and supercapacitor. The battery would deliver intense energy at longer duration while the supercapacitor would deliver intense power at shorter period. The results for this work were obtained through analysing data from the solar PV, battery and supercapacitor using MATLAB Simulink. By observation of the power profiles, comparison was made between the pure energy storage systems (ESS) against the hybrid energy storage systems (HESS) components. The outcome from the simulation portrayed that the performance of HESS was

better than the pure ESSs as means of energy storage backup. These shows that when the pure ESSs are used, more power and energy are used which may result to more costs and energy utilization. On the other hand, the HESS utilizes less power and energy signifying economic advantage of single HESS component against two pure ESSs.
