Wireless network is embracing unprecedented popularity in power distribution communication due to its flexible and cost-efficient coverage for the massive number of sparsely distributed service terminals. This paper evaluates the reliability and security of power distribution wireless networks. Technical suitability suggestions from the perspective of reliability are obtained based on the mapping between communication performance and service requirements. Security challenges on the protection of radio link and wireless terminals are analysed and overcome by proposed random-noise-disturbed encryption method and joint authentication scheme. The evaluations provide suggestions for the application of wireless network carrying power distribution services, and ensure the reliable and secure operation of power distribution network.
