Brushless generation systems have high reliability, so it is very suitable for remote area distribution networks. The dual stator winding induction generator (DSWIG) to be one of the suitable generating scheme which enable distributed generation (DG) with hybrid micro-grid for DC /AC loads. This work has a unique structure of DSWIG which facilitates simultaneous power flow through both the stator windings in rated speed range. First winding called as power winding and second winding called as control winding. Power winding generates constant frequency AC supply to meet AC loads and control winding generates DC supply through Static Excitation control to meet DC loads. To ensure reliability of hybrid micro grid system Battery Energy Storage System (BESS) has been incorporated with proposed generation scheme. Indirect field oriented current control has been used to validate the 1.5MW DSWIG. MATLAB/Simulink based simulation studies have confirmed that dual stator winding induction generator works properly and both stator windings will produce AC supply. Instantaneous slip frequency has been discussed to control the variable reactive power to the control winding, it will be implemented with prototype in future with 1.5KW capacity which in turn power winding will generates AC supply and control winding will generates DC supply.
