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.

Capacitance values for commercial capacitors are specified as "rated capacitance CR". This is the value for which the capacitor has been designed. The value for an actual component must be within the limits given by the specified tolerance. Typical values are in the range of (F), three to six larger than those of electrolytic capacitors. The capacitance value results from the energy (expressed in
