Abstract: With the emergent expansion of micro grid, the performances of microgrid subsequent to the various fault conditions have become an attractive area to be examined. This paper investigates the dynamic performance of the microgrid during (i) addition of non-linear load and (ii) fault triggered events. The microgrid consists of two DGs which are interfaced through a PE converter. The interface converters are equipped with P-F and Q-V droop control. The impacts of the droop control on the microgrid stability has been analysed in this work. The performance of the controllers in MATLAB/SIMULINK platform is also presented.
