Abstract
The battery energy storage systems (BESS) have been gaining notoriety in recent years due to the high penetration of renewable energies in distributed generation, with the aim of providing a dispatchable and reliable energy source, in addition to serving ancillary services and assisting in infrastructure and energy management. It is noteworthy that in this implementation a multi-cell converter is used, in order to expand the power supply capacity, reduce the ripples in the electrical variables and reduce the volume occupied by the inductors of the dc/dc converters. This study presents the design and simulation implementation of a decentralized Phase Shedding strategy for an energy storage system. The converter is modeled and control equations are presented, as well as the development of Phase Shedding and Auto- Interleaving, bringing the results obtained.
