—In this paper, electrical parameters of a microgrid containing distributed generation wind and fuel cell units are controlled in islanding mode operation. Islanding operation refers to isolation of a part of power system including distributed generation from the grid having continuous and independent operation. This has negative impacts on the isolated network including voltage and frequency dependence on load. These impacts and their solutions are studied in this paper. A proper controller using power electronics converters has been proposed. In order to verify the validity of the proposed control approach, it has been implemented and simulated on a 13-bus IEEE distribution power system containing a combination of distributed generation wind and fuel cell units.
