Therefore, this study presents a composite controller incorporating a global integral terminal sliding mode controller with a backstepping controller. . Fluctuations in distributed power supply and sudden changes in DC load power will lead to serious DC bus voltage fluctuations in DC microgrids, which will have a certain impact on the safe and stable operation of DC microgrids. The system inertia is enhanced by exploring the auxiliary power of DESS and thus t e stability of the voltage is improved. In addition, the microgrids suffer from an inherent low-inertia problem.
