Control strategy for secondary frequency regulation in hybrid energy storage considering real-time dispatchable power and maximum output constraints

open access: yesGlobal Energy Interconnection
Hybrid energy storage systems (HESSs) involved in secondary frequency regulation (FR) can overcome the technical limitations of single energy storage systems (ESSs). However, coordinating the control of ESSs with differing characteristics remains a major
