How can a dc microgrid reduce voltage fluctuations?

Improving the inertia of a DC microgrid is an effective way to reduce DC voltage fluctuations. Initially, the problem of the low inertia of DC microgrids is mainly solved by adding hardware devices, such as supercapacitors [6, 7]. However, their high cost is not conducive to practical engineering applications.
