In this paper, an AC/DC microgrid is proposed to reduce processes of multiple reverse conversions in the AC or DC microgrids and to facilitate the connection of the AC and DC energy resources and loads. Beside, according to the research the control of the voltage and frequency is a very important issue in the microgrids. Therefore, control schemes studied in this paper, are developed and published in order to improve the voltage and frequency stability of the microgrid operated in the stand-alone (islanded) mode. Results are achieved considering short-circuit fault and the uncertainty of the generators and loads verifying the correctness, accuracy and robustness of the controllers to stabilize and restore quickly the voltage and frequency of the proposed microgrid due to these disturbances.
Keywords: Microgrid, Voltage Control, Frequency Control, Energy Resources Modeling, PI Controller
