The significance of this research is in expanding the application scope of hybrid energy storage systems. The proposed control method addresses the limitations of traditional hybrid energy storage systems, which are restricted to DC buses, enabling more flexible applications in distributed energy storage devices.
An important observation is that throughout the power variation process, the total power output remained constant. These results demonstrate that the hybrid energy storage control strategy proposed in this paper effectively allocates power between the batteries and supercapacitors while maintaining a stable external power output.
Existing hybrid energy storage control methods typically allocate power between different energy storage types by controlling DC/DC converters on the DC bus. Due to its dependence on the DC bus, this method is typically limited to centralized energy storage and is challenging to apply in enhancing the operation of distributed energy storage.
At the same time, a strategy based on multi-agent theory is employed to enable multiple distributed energy storage sources to collaboratively achieve hybrid energy storage. This strategy can be directly applied to energy storage systems connected to the AC grid, facilitating more efficient utilization of renewable energy.
Adopting a Hybrid Energy Storage (HES) to realize VSG can maximize the advantages of different types of energy storage, improve system's frequency and inertia response capabilities and extend the life of energy storage.
