Microgrids (MG) are new concept of electric power networks consisting of Distributed Generation
(DG), renewable energy resources and sensitive loads. The goal of microgrid operation is to provide reliable
and high-quality electric power regardless of faults or abnormal operating conditions. Many control methods
have been employed to regulate the output power of DGs used in MGs. This paper presents a control scheme
for DGs of a power system, especially with Voltage Source Inverter (VSI) interface, for both grid connected
and islanded modes. A comprehensive study has been performed through PSCAD simulations of the inverterfed
MG behavior under both islanding and connected operation for different load conditions. The simulation
results prove the droop method efficiency in controlling the voltage and frequency of the inverter output which
is connected to the loads.
Key words: Connected mode, DG, droop method, islanding mode, microgrid, ,
