Design and verification of a hybrid energy storage system for a defined power profile

Abstract This article presents the design and development of a supercapacitor for defined power profiles, focusing on the selection process for an optimal supercapacitor to form a high-performance supercapacitor module. The study outlines the methodology for selecting suitable components based on energy and power density requirements, considering operational efficiency and durability under specific load conditions. A control algorithm for bidirectional power flow is developed to regulate the charging and discharging processes of the supercapacitor module, ensuring efficient energy management. Practical verification of the designed SC module is performed to evaluate the system dynamic response under various operational scenarios. The practical experimentation using the supercapacitor module is tested in laboratory conditions. The experimental results demonstrate the effectiveness of the control strategy in achieving bidirectional operation, confirming the suitability of the designed supercapacitor module for applications requiring fast power delivery and recovery.
