Coordination of various distributed generation (DG) units is required to meet the growing demand for electricity. Several control strategies have been developed operate parallel-connected inverters microgrid load sharing. Among these techniques, due lack essential communication links between coordinate DG within a microgrid, droop method has generally accepted in scientific community. This pape...

In the hierarchical control of an islanded microgrid, secondary control could be centralized or distributed. The former control strategy has several disadvantages, such as single point of failure at the level of the central controller as well as high investment of communication infrastructure. In this paper a three-layer architecture of distributed control is given, including the device layer, ...

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...
