Dynamic modelling, analysis and design of smart hybrid energy storage system for off-grid photovoltaic power systems

This thesis made a comprehensive study about the battery-supercapacitor hybrid energy storage systems for stand-alone photovoltaic power systems that aims to mitigate primary chemical battery operating stress by minimizing life-limiting factors such as high charging/discharging rate, fluctuating current and frequent charge-discharge transition. The results of this study demonstrate the effectiveness of extending the lifetime of the battery in such systems. The outcomes of this thesis could significantly contribute to energy researchers and industry practitioners to address the issues in rural electrification and to reduce the lead-time required in designing and implementing new hybrid energy storage solution from photovoltaic-battery power systems.
