Advancements and challenges in hybrid energy storage systems: Components, control strategies, and future directions

Abstract

Hybrid energy storage systems (HESSs) can considerably improve the dependability, efficiency, and sustainability of energy storage systems (ESSs). This study examines the components of HESS, including the different types of ESSs that are typically used in hybrid systems. The advantages of integrating various ESS types in hybrid systems are also covered, along with design considerations for HESS and the interconnection topologies, which include passive, active, and semi-active architectures. For HESS, several control techniques both traditional and intelligent-have been suggested, including filter-based control, droop control, sliding mode control, rule-based control, deadbeat control, model predictive control, fuzzy logic control, optimization-based control, supervisory control, feedforward control, unified control, and robust control. The current work also discusses HESS's difficulties and potential possibilities, including technological advancement, standardization, interdisciplinary cooperation, grid integration, environmental sustainability, security and dependability, and legislative and regulatory frameworks.
