     dynamics are the most important problems in the microgrid operation. in the islanded microgrid, the mismatch of parallel operations of inverters during dynamics can result in the instability. this paper considers severe dynamics which can occur in the microgrid. microgrid can have different configurations with different load and generation dynamics which are facing voltage disturbances. as a result, microgrid has many uncertainties and is placed in the distribution network where is full of voltage disturbances. moreover, characteristics of the distribution network and distributed energy resources in the islanded mode make microgrid vulnerable and easily lead to instability. the main aim of this paper is to discuss the suitable mathematical modeling based on microgrid characteristics and to design properly inner controllers to enhance the dynamics of microgrid with uncertain and changing parameters. this paper provides a method for inner controllers of inverter-based distributed energy resources to have a suitable response for different dynamics. parallel inverters in distribution networks were considered to be controlled by nonlinear robust voltage and current controllers. theoretical prove beyond simulation results, reveal evidently the effectiveness of the proposed controller.
