Hybrid Energy Storage Systems for Renewable Energy Integration: An Overview

Integration of Renewable Energy Sources (RES) into the power grid is an important aspect, but it introduces several challenges due to its inherent intermittent and variant nature. Hybrid Energy Storage Systems (HESS) is a reliable approach to overcome this issue. HESS combines various storage technologies to improve both the performance and reliability of the grid systems. In this review, we summarize the advantages and development needs of HESS in comparison to standalone Energy Storage Systems (ESS). The paper details different RES, their importance of storage in sustainable development, and the classification based on the present technologies. This review article brings insights into current HESS-implemented models in real-world applications and their performance metrics. Concisely, the work investigates the economic and environmental impacts from recent findings, the increasing trends and research tracks, as well as future directions in this emerging technology.
