Enhancing quality of power to sensitive loads with MicroGrid

The paper discusses the effectiveness of the MicroGrid (MG) in a distribution system. Combined heat and power (CHP) system has been used to enhance the overall efficiency of the power system. Microturbines have been used for CHP operation in this paper. The various methods of controls of the MG are also discussed. A simple and low cost model for MG based on frequency droop control for active power generation, has been proposed. The proposed model can be used in plug and play mode of operation of the MG. The model has been simulated on the MATLAB platform. Performance of the model has been studied under grid connected and under islanded condition.
