说明：  With increasing the presence of Microgrids in the power systems, investigating the MG stability during transient faults is necessary. This study investigates the transient stability analysis of a MG supplied by multiple inverter interfaced distributed generations during fault. The transient stability of a MG is highly depends on the IIDGs control strategy. A MG, simulated on Matlab/Simulink, including three IIDGs and two local loads connected to the IEEE 37-node distribution system is considered as test system. Simulation results show that the MG may lose its stability due to the transient over-currents during fault. By adding a transient current control loop to the voltage source inverter control strategy, the output currents are limited during fault. In the connected mode, an external fault is applied to the MG.
