Overview of Improved Droop Control Methods of Hybrid AC/DC Microgrid Interlinking Converter

摘要

The hybrid AC/DC microgrid can combine the advantages of AC microgrid and DC microgrid, and it can reduce the loss caused by multi-stage power conversion, so it has become a hotspot in recent years. And the interlinking converter (ILC) between the AC subgrid and DC subgrid can ensure the balance of power of both sides and maintain the stability of the entire system. In this paper, the basic structure of hybrid AC/DC microgrid is introduced, the principle of traditional droop control is analyzed briefly. The main content of this paper is to analysis and summary the improved droop control methods of interlinking converter in hybrid AC/DC microgrid.
