Voltage Regulation Of Dc Link For Microgrid Stability And Operation
Equal power-rating at different power set points in an isolated or grid-connected mode may result in inter-unit circulating power due to a significant mismatch between power generation and demand during network contingencies. This mismatch can occur when there is a substantial imbalance between powe...
