Reactive power sharing is one of the main issues in the control and operation of an autonomous Microgrids (MGs), especially for MGs composed by power generation interfaced with the MG distribution by means of Power Electronic Converters (PEC). Among the various MG control techniques, the droop is the one that has been widely applied thanks to the possibility of achieving a communication-less regulation of the MG. However some issues arises as far as reactive power and voltage control is concerned. The aim of this study is to draw some analytical consideration of reactive power sharing in droop-controlled autonomous MGs in order to highlight the parameters and configuration that can lead to undesired operational conditions.

Abstract
Reactive power sharing is one of the main issues in the control and operation of an autonomous Microgrids (MGs), especially for MGs composed by power generation interfaced with the MG distribution by means of Power Electronic Converters (PEC). Among the various MG control techniques, the droop is the one that has been widely applied thanks to the possibility of achieving a communication-less regulation of the MG. However some issues arises as far as reactive power and voltage control is concerned. The aim of this study is to draw some analytical consideration of reactive power sharing in droop-controlled autonomous MGs in order to highlight the parameters and configuration that can lead to undesired operational conditions.
