摘要: The medium-voltage direct-current (MVDC) ship power system has been extensively investigated and discussed in recent years. This paper presents an alternating current/direct-current (AC/DC) flow algorithm based on complex affine arithmetic for the zonal MVDC shipboard presence of variation. converter effect is considered, model proposed model. An affine-analysis-based sequential method adopted to solve AC/DC flows. With algorithm, bounds bus voltages can be effectively obtained. A relative influence factor defined quantitatively assess variation voltage profile. Four cases are studied detail demonstrate applicability algorithm. useful network architecture design, planning, online operations systems when such decisions subject
