This paper proposes a novel non-isolated high voltage gain dc–dc converter with boost2 (B2) technique. The derived single-switch hybrid voltage-lift topology generates higher conversion ratio less component counts than traditional converters. Furthermore, to show its superiority, the proposed is compared other recent converters in terms of number power components such as inductors, capacitors, ...

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...

In this paper a novel distributed control algorithm for current sharing and voltage regulation in Direct Current (DC) microgrids is proposed. The DC microgrid is composed of several Distributed Generation units (DGus), interfaced with Buck converters, and current loads. The considered model permits an arbitrary network topology and is affected by unknown load demand and modelling uncertainties....

A high-performance photovoltaic (PV)-battery hybrid power conversion system (HPCS) which is integrated to a microgrid using a quasi-Z-source inverter (qZSI). The battery system is directly connected to the intermediate dc link of the qZSI without any further converter which reduces the size and the cost of the power electronic interface. A controller equipped with a vocal compensator is designe...

In modern infrastructure, the demand for DC power-based appliances is rapidly increasing, and this phenomenon has created a positive impact on the acceptance of the DC microgrid. However, due to numerous issues such as the absence of zero crossing, bidirectional behaviour of sources, and different magnitudes of fault current during grid connected and islanded modes of operation, protecting DC m...
