摘要在风电规模不断扩大的背景下,多端柔性直流输电（VSC-MTDC）成为一种灵活、经济的输电手段。本文以VSC-MTDC与交流电网共同构成的交直流并列运行系统为研究对象,分析并完成了计及多种功率控制模式的概率潮流计算方法。首先,建立含VSC-MTDC的交直流潮流模型;其次,在潮流计算中考虑实际调度场合下VSC-MTDC的多种功率控制模式,进一步基于拉丁超立方采样法计算概率潮流;最后,以广东南澳多端柔性直流输电系统作为算例,验证本文算法的有效性。

Abstract：Under the background of the continuous expansion of the scale of wind power, VSC-MTDC provides a flexible and economical way of transmission. In this paper, a probabilistic power flow calculation method considering power control mode is proposed for AC-DC parallel operation system composed of VSC-MTDC and AC power grid. Firstly, the AC/DC power flow model with VSC-MTDC is established; secondly, the multi-power control modes of VSC-MTDC are considered in power flow calculation, and then the probabilistic load flow is calculated based on Latin hypercube sampling method; finally, the effectiveness of the proposed method is verified by a case study of Guangdong Nan'ao multi-terminal flexible HVDC transmission system.

Key words： wind power VSC-MTDC power control mode probability flow
