Automatic droop control for a low voltage DC microgrid

IET Generation, Transmission & Distribution, 2016
A DC microgrid (DC‐MG) provides an effective mean to integrate various sources, energy storage units and loads at a common dc‐side. The droop‐based, in the context of a decentralised control, has been widely used for the control of the DC‐MG. However, the conventional droop control cannot achieve both accurate current sharing and desired voltage ...
