Overview of Architecture and Planning of Cyber Physical Distribution System

With the deep integration of advanced information and communication technology, Internet of Things technology and power grid technology, and the deepening application in the field of power distribution, power distribution system has developed into a typical cyber physical distribution system. The connotation and method of traditional power distribution network planning cannot adapt to the development demand of integrated system. This paper reviews cyber physical distribution system (CPDS) and distribution network-internet of things (DN-IoT). Firstly, the connotation and technical characteristics of cyber physical distribution system and distribution network-internet of things are analyzed. Then, the relationship between cyber physical distribution system and distribution network-internet of things is explored according to their technical framework. Then, a technical framework of cyber physical distribution system planning is developed combining the traditional power distribution network planning framework with distribution network-internet of things framework, and planning constraint conditions are proposed based on the double-layer coupling characteristics of information and physics. Finally, the future research direction of cyber physical distribution system planning design is prospected.
