Hybrid AC/DC microgrids facilitate the procedure of DC power connection into the conventional AC power system by developing the distributed generations (DGs) technologies. The conversion processes between AC and DC electrical powers are more convenient by hybrid systems. In this paper, an energy management system (EMS) for a hybrid microgrid network is proposed due to the optimal utilization of...

Abstract There are risks of resonant instability exiting in the DC distribution system configured with battery energy storage devices because capacitors and inductors network fast speed-controlled DC-DC converters. The needs to provide voltage support when it operates an isolated island mode no AC or sources at that moment. To explore key factors affecting network, a three-terminal consisting c...

This paper proposes a novel topology of multilevel current source inverter which is suitable to apply in low/medium voltage. The proposed topology is capable of producing desirable bidirectional output current levels. Furthermore, it can employ symmetrical DC current sources as well as asymmetrical ones which is a significant advantage. Asymmetrical mode makes it possible to generate a great nu...

This work introduces a multiple-input, multiple-output (MIMO) isolated converter for low-power applications involving residential DC nanogrids and nanogrids. The topology has multiport characteristic that allows the integration of loads sources with distinct ratings, e.g., photovoltaic (PV) modules, battery banks, loads, AC grid. structure relies on DC-DC multi-winding multidirectional flyback ...

In the context of sustainable buildings, this paper investigates power flow management for an isolated DC microgrid and focuses on efficiency and energy cost reduction by optimal scheduling. Aiming at high efficiency, the local produced power has to be used where, when, and how it is generated. Thus, based on photovoltaic sources, storage, and a biofuel generator, the proposed DC microgrid is c...

This chapter titled “Hybrid AC/DC Microgrids: Solution for High Efficient Future Power Systems” presents a new configuration for future power systems which is the hybrid AC/DC gird for high efficient connection of the inherent AC and DC sources and loads. Three-phase AC power systems have been in dominant position for over hundred years due to invention of transformer and the inherent character...
