A New Approach for Soft Synchronization of Microgrid Using Robust Control Theory

چکیده مقاله

Microgrid is the main part of future electrical power systems, called 'smart grids'. In this context, synchronization of a microgrid with utility or other microgrids will be a crucial and commonplace task during the power system operation. Based on the robust control principles, a new approach for synchronizing microgrids with utility was presented in this paper. Uncertainties of the dynamic model of microgrids were considered as multiplicative perturbations. Based on the uncertain model, a robust controller was designed by means of µ synthesis analysis so that the robust stability and performance of the system could be maximized. The simulation results confirmed the effectiveness of the proposed control strategy.
