ABSTRACT A microgrid is a power grid consists of distributed power generation units and loads. Microgrid is also a system that can operate in grid-connected mode and islanding (autonomous) mode. The control of distributed power generation units in microgrids is necessary for reliability and continuity of power grid. In this study, the droop control method which is widely used in the control of distributed power generation units in intelligent microgrids has been examined. The droop control method, which operates similarly to the primary frequency regulation system of the conventional power grid, does not have communication with other distributed generation units. In this study, the design steps of the droop controller which is designed in order that linearly considering the relationship between active power – frequency (P-f) and reactive power – voltage (Q-V) and regulating the deviations that occur have been examined in detail. The designed droop controller has been compared with voltage - current control and hierarchical control methods.
