Summary

• What is new: A novel decentralized control method for managing heterogeneous battery energy storage systems (BESSs) autonomously based on each battery’s characteristics.
• Why this is important: The need for a stable power supply in renewable energy systems, especially with the future incorporation of massive and pluggable heterogeneous batteries.
• What the research proposes: A control method that enables autonomous operation of each battery using a single broadcast signal per battery type, ensuring system stability and robustness even with battery failures.
• Results: Numerical simulations demonstrated the method’s effectiveness in maintaining robust power tracking and equalization of the state of charge among different batteries without requiring inter-battery communication.
