摘要：
The rapid development of the distribution Internet of Things(IoT) has further enhanced the coupling between the power physical network and the power communication network. A single failure of the power communication network will interact on the stable operation of the power physical network and even the entire distribution IoT. Therefore, the evaluation of important nodes in the power communication network has theoretical and practical values. First, based on the distribution network topology of a domestic city where the pilot project of power distribution IoT is launched, in this paper, a power communication network model including ring network cabinets, switching stations, and branch boxes is established. Secondly, the coupling between the power physical network and the power communication network mechanism is taken into account, and a power communication coupling network model based on the complex system theory is established.Moreover, combined with the power communication network node importance evaluation index set based on the complex system theory, a node importance evaluation mechanism based on the normal cloud combination weight method and variable weight coefficients is proposed, so that the node importance evaluation of the power communication network is realized.Finally, the distribution network of a domestic power distribution Internet of Things pilot city is taken as an example, a communication network OPNET simulation model is established, and the effectiveness of the node importance evaluation method proposed in this paper is verified. © 2022, High Voltage Engineering Editorial Department of CEPRI.
