The concept of regenerative energy management in dual-ac-dc grids in presence of pulse-load is investigated in this paper. The results of this work are applicable to dual ac-dc micro-grids with flywheel (FW) energy storage systems. Undesirable impacts of the pulse-load, on the dual system, are mitigated through both the proposed system configuration, and time-coordination between the occurrence of pulse-loads and the release of kinetic energy from the flywheel. The obtained results are validated through experiments.
