6 FAQs about [Microgrid voltage deviation]

How to solve dc microgrid control problems in a distributed manner?

A new voltage compensation mechanism is presented in this study to resolve the control issues of DC microgrid in a distributed manner. In this mechanism, a fractional-order voltage compensation term is used in the outer controller loop which eliminates the voltage deviation in the steady-state condition.

How to improve the stability of DC microgrids?

The inertia of the system can be increased by reducing the degree of bus voltage oscillations and solving the problem of large voltage deviations. Current methods for improving the stability of DC microgrids are positive and passive damping strategies.

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.
