Abstract

Aiming at the DC distribution network based on the droop control, this paper proposes that the intersection of the internal characteristics of the node converter droop control and the external characteristics derived from the parameters of the DC distribution network is the actual node operation point. The quantitative relationship between the droop control characteristic parameters and the converter functions is discussed, and the comprehensive droop control characteristics of the multi-converter node is analyzed. The automatic adjustment method of droop control, containing the secondary adjustment and the third adjustment, is presented, and the power flow algorithm of DC distribution network, which considers the impact of power flow controller, droop control and automatic adjustment method, is derived. Finally, three cases about power flow controller, the secondary adjustment and the third adjustment are used to verify that droop control and its related regulation methods can optimize the operation conditions of DC distribution network.
