ABSTRACT

Traditional AC distribution network usually adopts “closed loop design, open loop operation” mode of power supply, which restricts the further increase of the power supply reliability. When the DC network joins in, it is possible to realize the closed loop operation through reasonable control strategies, so as to improve the distribution network reliability. This paper mainly studied the operation mode and its reliability assessment of the AC/DC hybrid distribution network. Two-terminal power supply distribution structure was selected to be transformed to AC/DC hybrid distribution network containing flexible HVDC. Then the system control and operation mode of the new distribution model was studied and discussed. Adopting sequential Monte Carlo method based on the minimal path sets, the reliability of AC/DC hybrid distribution network was assessed and compared with traditional AC distribution network according to the cases.
