Advanced feed-forward strategy to dynamic control of the islanded micro grids

Abstract

In this paper, by choosing the islanded structure for DER, the problem of voltage and frequency control in micro grids is discussed. The proposed control scheme has been used as a feed forward compensation strategy to reduce the nonlinear effects and to compensate for the load dynamics. Thus, the mathematical islanded model of DER system has been introduced and then, the voltage and frequency controllers have been designed to achieve fast and stable response and also zero steady state error. The operation of system in different load conditions is checked by Matlab-Simulink software. The simulation results show the robust operation of closed loop system composed with designed controller.
