The most popular ESSs used in this context are battery energy storage systems (BESS) and supercapacitors (SC). Therefore, the hybrid energy storage system (HESS) can be comprised of BESS and SC to guarantee the reliability of the system and improve the overall performance of the BESS and power network [ 3 ].
B. A. Aderemi, A. T. Puati Zau, S. Daniel Chowdhury, T. O. Olwal, and A. M. Abu-Mahfouz, “Hybrid Battery Technologies with Battery Management System in Power and Energy Sectors”.
Hybrid energy storage system HESS have three primary setups that are regularly utilized. The first is detached, the second is semi-dynamic, and the third is entirely dynamic HESS, consisting of qualities and boundaries.
Optimal coordination of energy storage systems (ESSs) significantly improves power reliability and resilience, especially in implementing renewable energy sources (RESs) [ 2 ]. The most popular ESSs used in this context are battery energy storage systems (BESS) and supercapacitors (SC).
The battery is needed to improve the reliability of variable renewable energy plants by optimizing power production. However, the fluctuating charge and discharge of the battery energy storage system (BESS) is one factor that negatively impacts its lasting capacity.
