Abstract
With the access of distributed power sources such as wind power and photovoltaic,energy storage systems,electric vehicles,integrated energy system and other devices,the distribution network has gradually become a service platform to meet the complex and interactive service needs for all kinds of power users,which is of greater significance in order to guarantee the reliability,security,stabilization and economy.Aiming at the development demand of the distribution network in developing the new-type power system,the high-and medium-voltage distribution network structures are proposed with hierarchical paralleling loop network platform in this paper.Firstly,the"212"two-side power supply and"323"three-side power supply chain structure were proposed to construct 110 kV high-voltage distribution network.The structure adopted closed-loop design and loop operation,which can improve the safety of power supply and reduce the line investment.Secondly,the 220 kV substation was proposed as the upper power point of the new-type power system distribution network.Then,the two proposed distribution network structures were applied to the 110 kV substation.Finally,the"212"type two-side power supply loop structure was used to construct 10 kV medium voltage distribution network.It is of great significance to improve the medium voltage distribution network structure to build a stronger and more elastic distribution network.关键词
