Abstract

The paper presents a microgrid architecture and control allowing full dispatchability of the power generated by distributed energy sources. To this purpose, full advantage is taken of power control and energy storage capability of distributed generation units and of the Utility Interface, a grid-interactive power converter equipped with energy storage and located at the point of common coupling. A master-slave power-based control ensures good efficiency and power quality in the stationary regime, fast dynamic response, full dispatchability, and soft transition from on-grid to off-grid operation, both in case of intentional and non-intentional islanding.
