Abstract:Direct current (DC) microgrid is being increasingly investigated in modern power grid. An important issue in DC microgrid operation is to ensure proper current sharing among converters. While this has been addressed through droop control, the resulting voltage deviation in DC bus has to be compensated. This talk will report our recent research on a new distributed secondary control scheme for both current sharing and voltage restoration. A key part of our scheme is the integration of a new parameter ‘virtual voltage drop’ defined from droop gain and line resistance. Our secondary control is simple and easy to design and implement. It can also handle both resistance loads and constant power loads (CPLs). We will present case studies with both simulations and experiments to demonstrate the effectiveness of our scheme.
