Abstract
An islanded AC microgrid usually consists of multiple Voltage Source Inverters working in parallel. When the impedances of the feeders connecting the VSIs to the Point of Common Coupling(PCC) are equal, the active and reactive power demanded by the load will be equally distributed between the two VSIs. However, when the VSIs are at unequal distance from the load, the connecting feeder impedances will be different. When the feeder impedance values are not equal to one another, the reactive powers shared by each of the VSIs will become unequal even if they are of same rating. The reactive power distribution is also affected if there is an asymmetry in the physical location of the loads. There are several control algorithms available in the literature to reduce this mismatch in reactive power sharing among the VSIs. This paper will explain the step by step procedure to build a MATLAB/SIMULINK model of an islanded microgrid consisting of two parallel VSIs and will help to understand the effect of feeder impedances and location of load on power sharing among the VSIs.
