Abstract

In order to provide autonomous power sharing of the conventional droop-control scheme for multiple power converters in isolated micro-grids, two consensus-based droop-control schemes will be examined. Since the conventional uniform droop gain ratio scheme requires identical droop gain ratio settings among all converters, applications to large-scale systems are restricted. An alternative scheme with the non-uniform droop gain ratio is proposed in this paper to simplify the droop gain setting while maintaining the perfect power sharing. Also, this new scheme is more robust since it is independent of particular gain settings. Real-time simulations of a micro-grid system are conducted to validate the effectiveness of this robust consensus-based droop control method.
