Description
Summary:	The concept of the micro grid is still growing with regard to co-ordination strategies and the development of proper controllers to enhance the reliability aspects under different operating modes. In this context,due to the growing interest of renewable energy sources droop based inverter dominated micro grids are one of the fastest emerging technologies. This research paper aims to study reactive power sharing and voltage variation under different scenarios in an inverter dominated islanded micro grid. In this regard, non-linear equations that describe the model have been derived and an averaged model is used in the derivation of the mathematical model resulting in simplified equations which are used to model large signal equivalent circuits in PLECS software. In addition, the impact of load perturbations, filter parameters, line impedances and droop variations are analyzed
