Abstract: This work considers an AC/DC microgrid that is composed by an integrated PV/wind microgrid, a storage system (battery), DC and AC loads, and between the two buses there is a bidirectional static converter to transfer power. The PV source is connected into the DC bus through a Booster converter while the double fed induction generator that is used in the wind energy system is connected directly with the AC bus. Using the fact that there is a complementarity role between the renewable sources, the purpose of this work is to analyze and improve the power flow dynamics between the AC and DC buses by designing an appropriate control strategy that stabilizes the microgrid during a lack of power generation at one of the renewable sources. Several simulation studies are presented to illustrate the performance evaluation of the proposed microgrid.
