Solid-State Technologies for Flexible and Efficient Marine DC Microgrids

This paper presents flexible operating modes of marine DC microgrids and main advantages employing energy storage systems into such microgrids. Scaled-down with two buses integrated storages are considered in this paper. To verify superior features the solid-state technologies systems, a wide range system experimentally demonstrated, ranging from basic to advanced modes: voltage regulation, power sharing control, soft start (smoothly charging bus potential nominal level), seamless transition (transiting open-bus closed-bus operations), load leveling (flattening generator loads by systems), transient mitigation (mitigating sudden changes zero-emission (powering networks near port). The experimental results show that provide ship owners flexibility management system, fuel savings, environmental compliance port.
