In the past decade, the implementation of battery energy storage systems (BESS) with a modular design has grown significantly, proving to be highly advantageous for large-scale grid-tied applications. However, despite its increasing prevalence, there is a noticeable absence of review papers dedicated to this specific topic.
Prospective avenues for future research in the field of grid-tied modular battery energy storage systems. In the past decade, the implementation of battery energy storage systems (BESS) with a modular design has grown significantly, proving to be highly advantageous for large-scale grid-tied applications.
The stored energy requirements for the MMC topologies is 40 J/kVA, according to . Therefore, the energy storage is 40,000 J and 45.5 J for capacitor and inductor, respectively. The number of semiconductors is smaller for the 2 L converter.
Recent works have highlighted the growth of battery energy storage system (BESS) in the electrical system. In the scenario of high penetration level of renewable energy in the distributed generation, BESS plays a key role in the effort to combine a sustainable power supply with a reliable dispatched load.
