Abstract :
The paper presents the study of the multi-functions of a power electronic converter in distributed generation systems. The converter is an interface of a DG unit and also may perform other functions with the help of the appropriate control strategies. In steady states, the converter is used as an interface for the DG unit to delivery the power, and acts as an active power compensator in a hybrid compensation system for the local DG network to improve the overall power quality; while in power system transient and dynamic situations, the converter can help to improve the stability of the power systems. The operation of the converter in performing the multi-functions has been described. The control strategies under various operation conditions have been discussed. Simulation results are presented to demonstrate that the converter can effectively perform various functions, including the stability improvement of DG systems
