Development of effective technique for integration of hybrid energy system to microgrid

Abstract

Due to lack of energy resources, renewable energy sources have increased fabulous consideration and settled rapidly in recent years. It is a very decisive issue to integrate hybrid energy system to the microgrid. In this paper, a control model for integration of hybrid energy sources to the microgrid and the effectiveness of the control algorithm for DC/DC converter under variation of different load demands are presented. A nearly constant dc voltage at the output of hybrid energy system is preferred for high efficiency So, there is a necessity for developing control techniques for a grid integration hybrid system including a method for output voltage control that stabilizes the voltage and dc-link capacitance. The simulation results of MATLAB/SIMULINK model report that the proposed control algorithm has a good performance. Therefore an idea of an effective technique for integration of solar/wind system to microgrid has been given.
