Abstract
The variations in loads can be defined as either increment or decrement in the load. Variation in load causes a similar change in the amount of current which produces opposite variation in output voltage. Microgrids typically use renewable energy resources to meet varying load demands of the local area. Such sources need power electronic converters for controlling proper voltage level for efficient operation. Hence it becomes essential to design control scheme for the DC-DC converters to stabilize the voltage in DC micro grids under any type of load variations. This research work proposes a DC micro grid structure in which sliding mode controller based DC-DC converters are implemented. Microgrid structure is then simulated using MATLAB SIMULINK where output voltage regulation is achieved efficiently in case of rise as well as fall in the load connected on DC micro gird.
