This paper presents the design and implementation of a robust joint (P+Resonant) controller for single-phase islanded microgrid in the presence of different load dynamics. Microgrid system consists of different unknown and uncertain load dynamics. The aid of this proposed controller is to achieve robust performance to track the instantaneous grid reference voltage against these uncertain load dynamics. The fault current tracking performance of the controller has also been discussed. The simulation work is done via MATLAB/SimPower system toolbox. It is observed that the proposed controller has successfully tracked the reference grid voltage with minimum steady-state error.
This paper presents the design of a high performance robust resonant controller for the islanded single-phase microgrid operation on different loads conditions. The design of the controller is done using the results of Negative Imaginary approach. The performance of the proposed controller has been found much effective to track the instantaneous reference grid voltage. The simulation work has been done with the help of MATLAB/SimPower System toolbox. This shows that the proposed controller provides effective control of voltage against the uncertain load conditions.
