Introduction With the development of flexible DC technology and more and more distributed generation and energy storage equipment connected to the grid， in order to better satisfy new energy access and development of urban smart distribution network， this paper assesses the reliability and economy of flexible DC distribution network.
Method This paper calculated the reliability assessment of Flexible DC Distribution by Minimum Path Method and evaluated the economy， which selected the demonstration project in Zhuhai as the research object.
Result With the localization and maturity of IGBT and IGCT devices， the economy and reliability of Flexible DC Distribution network will gradually be better than that of AC distribution network.
Conclusion The relevant research results of this paper can provide important reference and foundation for the construction of flexible DC distribution Network projects in the future.
