An Improved Power Control Strategy for Hybrid AC-DC Microgrids. Int. J. Electr. Power Energy Syst. 2018, 95, 364–373. [ Google Scholar] [ CrossRef] [ Green Version] Adi, F.S.; Song, H.; Kim, J.-S. Interlink Converter Controller Design Based on System Identification of DC Sub-Grid Model in Hybrid AC/DC Microgrid. IFAC-Pap. 2019, 52, 45–50.

Are microgrids AC or DC?

Microgrids can be classified as AC or DC based on the usage of the AC/DC distribution buses. In the present scenario, hybrid microgrids have gained their importance, because of their ability to overcome the limitations of AC/DC microgrids such as the use of multiple converters, poor conversion efficiency, and voltage drop issues.

How to control a hybrid microgrid?

With regards to hybrid microgrid, similar control can be used within AC and DC subgrids, but special control strategy needs to be developed for ILC. The control schemes for ILC can be based on droop control [17, 19] or communication-based control [20, 21]. A more robust control can be obtained by using a combination of these control schemes.

Why are hybrid microgrids important?

In the present scenario, hybrid microgrids have gained their importance, because of their ability to overcome the limitations of AC/DC microgrids such as the use of multiple converters, poor conversion efficiency, and voltage drop issues. A hybrid microgrid is formed by combining AC–DC microgrids.
