What is Microgrid technology?
It is a small-scale power system with distributed energy resources. To realize the distributed generation potential, adopting a system where the associated loads and generation are considered as a subsystem or a microgrid is essential. In this article, a literature review is made on microgrid technology.
What is the difference between AC microgrid and dc microgrid?
Compared with AC microgrids, DC microgrids have no problems in reactive power, phase and frequency, and DC voltage has become an important indicator of system stability [ 3 ]. In DC microgrid system, in order to ensure the stability of DC voltage, it is necessary to coordinate the control of multiple microsources.
How to control a dc microgrid system?
An effective control strategy should be employed for a DC microgrid system's well-organized operation and stability. Converters are critical components in the operation of DG microgrids as they ensure proper load sharing and harmonized interconnections between different units of DC microgrid.
