Abstract - In this paper, an improved self-frequency control strategy is proposed for distributed generation units (DGs) connected in a micro grid. Micro grid works with two operating modes of operation such as grid integrated mode and islanded mode of operation. In case of grid connected operation micro grid is connected to main grid having large system inertia which helps to maintain micro grid frequency almost to nominal value. But in case of islanded mode operation micro grid must supply its own demand and maintain its frequency. There are various methods or control techniques for distributed generation to control active power sharing as well as frequency in islanded micro grids. Generally most commonly used method of load frequency control is droop control. In that active power – frequency is used for DG controller and frequency deviation is recovered by DG itself by self-frequency recovery control without using any secondary frequency control. But the electrical distance i.e. impendence between each DG and loads are different which may cause frequency deviation among the DG units. These differences are fed into the integrators of self –frequency recovery control which may cause the error in operation of active power sharing. So to solve this problem new technique or control method is developed which share active power more accurately. This method is compensation control method. In that active power sharing is done by considering droop coefficients of each of DG units.
