This paper presents the design and implementation of a standalone photovoltaic (PV) system using ultracapacitors as an energy storage unit. Ultracapacitors offer a high power density and long life cycle and could improve PV systems efficiency when subjected to peak loads. The setup is used to evaluate the direct parallel connection between the PV panel and the ultracapacitors bank without additional...
This paper presents a new robust control scheme for the efficiency optimization of an ultracapacitor-based hybrid energy storage system. The purpose is to improve the performance of the battery supply with the addition of an ultracapacitor as an auxiliary energy storage device for electric vehicles applications. The control scheme is based on an internal hysteresis-based current control loop combined...
