This paper proposed a new voltage control strategy for an islanded Microgrid (MG). A MG is consists of several Distributed Generation (DG) and local loads and controllers which it should be capable to operates in both connected and disconnected mode from main grid. Often there are some uncertainties in load and system parameters in isolated mode hence, robust control of electrical quantities is necessary for the system. The control structure proposed utilizes an internal oscillator to frequency control and a PI controller to voltage control which it is tuned based on Kharitonov’s theorem. D-stability approach has been used to fine tuning of PI controller. The simulation results show that the proposed control strategy based on Kharitonov’s theorem has a very effective performance in robust control of voltage.
