Abstract This paper presents the power flow modelling for AC/DC hybrid islanded microgrids including droop-controlled distributed generation units, secondary frequency and voltage restoration control AC side of microgrid, DC microgrid. The interlink converter between includes a frequency-voltage droop control, considers effect microgrid side. Two case studies are presented model evaluation, in ...

A microgrid is considered to be a smart power system that can integrate local renewable energy effectively. However, the intermittent nature of causes operating pressure and additional expense in maintaining stable operation by management microgrid. The structure multi-microgrids provides possibility construct flexible various trading framework. In this paper, order reduce adverse effects uncer...

In this paper, different types of synergetic controllers (SCs), such as simple SC, piecewise linear function form controller, improved controller with terminal and fast SC have been designed applied to an islanded DC microgrid. To be able make the design independent from system component values, a generalized mathematical method has derived for all power electronics-based subsystems microgrid s...
