A Reliability Evaluation Method for a Power Distribution Cyber-Physical System Based on Wireless Access Networks

The communication network plays an increasingly important function in the Cyber-Physical Distribution System (CPDS) to ensure a dependable power supply as the quantity and type of terminal devices in power distribution systems increase.This article examines CPDS reliability in the context of wireless access conditions. We begin by developing a reliability model specifically for communication channels within a 5G network. Additionally, we introduce an enhanced evaluation method using an improved minimal path approach. Simulation results demonstrate that 5G communication technology significantly enhances system reliability, offering valuable insights for optimizing CPDS operations. Keywords: CPDS reliability, 5G communication network, wireless access, power distribution system,communication network reliability, improved minimal path method.
