Abstract Since the islanded AC Microgrid is affected by impedance of line, it difficult to coordinate voltage regulation and reactive load distribution. A distributed secondary controller based on observer proposed for isolated Microgrids, does not need more communications. This method can guarantee estimated average equals actual output voltages that converge nominal values, realize accurate p...

Microgrids gain popularity due to their economical and environmental benefits along with low power losses smaller infrastructure. However, it has several operational challenges such as quality, system instability, reliability, protection issues. Microgrid strategy is a prime issue for the reliable operation of microgrid. The microgrid scheme must meet essential conditions grid-connected islande...

Abstract A distributed autonomous economic control strategy is proposed to realize the operation of DC microgrid in islanded state. The first introduces incremental cost primary control, but due influence line impedance, it not possible precisely achieve consensus at each unit, and generates a steady-state error. To overcome this problem, secondary based on dynamic algorithm designed basis whic...

Microgrids can bring electricity power to rural communities or isolated military forward operation bases. For many rural areas, renewable powers could be the cheapest power sources available. Utilizing renewable power sources and energy storage systems such as batteries requires new power and voltage control strategies. In addition, these microgrids may be reconfigured frequently. Therefore, th...
