Using ultracapacitors to optimize energy storage in a photovoltaic system

In this paper, a hybrid energy storage system was implemented using batteries and ultracapacitors. The goal of the research is to manage and to optimize energy flow from sources considering consumer demand. Ultracapacitors are requested during power demand, so batteries function under better conditions by avoiding deep discharges. Ultracapacitors role is very important, particularly when temperature is considered. Our results were obtained by simulation in order to confirm the performance and advantages of the global system.
