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...

Electrification to rural and remote areas with limited or no access to grid connection is one of the most challenging issues in developing countries like Iran. Most of electricity  demand is met by diesel generators in Iran remote areas, although they create environmental problems and economic concern. These issues can be minimized by hybrid renewable energy systems. This research paper aims at...

In a standalone hybrid wind-diesel-battery system, the battery lifetime is often optimistically overpredicted by hybrid system designers and battery manufacturers. As a result, battery replacement takes place more often than required. One of the reasons is due to the underestimation of battery wear from the short charge-discharge cycles, otherwise known as microcycles. A microcycle takes place ...
