A Battery Management System for Efficient Adherence to Energy Exchange Commands Under Longevity Constraints

This paper is focused on the problem of controlling the energy storage such that the energy exchange between the storage and the remaining system is performed in the required amount with maximum efficiency, and that all the constraints for the storage system longevity are adhered to. There is a huge need for such storage management in energy flow optimization of microgrids where energy flows from/to storages are planned in order to achieve maximum gain in microgrid operation. The case of a valve-regulated lead-acid battery is elaborated. The underlying computation tractability and the performance of such a battery management system is demonstrated both in simulation and experimentally.
