With the assessment of single-phase microgrids (MGs), three-phase/single-phase (TP/SP) hybrid multi-microgrids (MMGs) are emerging, provided with more complex architecture. This paper deals with the black-start problem for TP/SP MMGs in islanded mode caused by an unscheduled breakdown from the main grid. The three-phase units, such as energy storage systems (ESSs), photovoltaic (PV) systems, and loads,...
With the popularization and application of microgrid projects, the multi-microgrids (MMGs) with three-phase / single-phase (TP/SP) architecture is formed in a plurality of adjacent microgrids with certain needs. Due to the complexity of the topology and the diversity of the power supply modes, the MMGs can operate in various modes. It is an urgent problem to realize the flexible seamless switching...
In this paper, a novel type of voltage control strategy based on internal model robust and compound control is proposed for three/single-phase hybrid multimicrogrid, which is composed of two parts, feedforward control and internal model robust feedback control. Feedforward control is mainly used to improve the dynamic response and reduce the steady-state error of the system. The objective of the internal...
