摘要：
The bidirectional DC-DC converter operating in the buck mode is one of the main factors causing the resonant instability in the DC distribution network. Firstly, the impedance model of the three-phase VSC considering the dynamic process of the AC system and the one of the bidirectional DC-DC converter are established in this paper through a simple case of a DC distribution network. The influence of the main circuit parameters, the control system parameters and the steady-state operation points on their impedance models has been analyzed. The mechanism of the resonant instability in the DC distribution network induced by the DC network equivalent inductance and the bidirectional DC-DC converter is therefore revealed. Secondly, an active damping control strategy of the DC current feedback of the bidirectional DC-DC converter is proposed by considering the impedance characteristics required for the DC distribution network resonance suppression. After that, the influence of the damping controller parameters on its impedance characteristics is studied. Thirdly, taking the parallel resonance suppression of the battery energy storage device and the series resonance suppression of the DC network as the two constraints, the expression of the parameter selection range of the damping controller is presented. Finally, the correctness of the calculation formula is verified by the electromagnetic transient simulation. © 2022 Power System Technology Press. All rights reserved.
