Abstract :
Energy storage systems are mandatory in renewable energy based power supplies. They work as both an energy buffer and a backup. Regarding the renewable energy sources intermittent behavior and the load profile, high energy and power density are important requirements. To achieve both, this paper presents a modular design of a hybrid storage system including supercapacitors and batteries, benefiting from resizing possibility, optimized control strategies and improved reliability. Its performance in a renewable energy standalone power supply is analysed.
