Abstract—The power distribution and utilization network is an important link between the grid and the user. The data privacy protection is related to the secure and stable communication of the whole network. Based on quantum secure communication and combined with existing power security protection measures, this paper proposed a quantum key application solutions. The system architecture contained the primary station layer, access layer and terminal layer. Through the quantum key distribution network, the key generation devices of both sides of the communication negotiated to generate the quantum key, which was used to encrypt the transmitted data. In the aspect of quantum key distribution, the paper proposed the distribution mode of online distribution and offline distribution, which promoted the flexible distribution of the terminal side quantum key, and realized the low-cost application. The feasibility of the scheme was verified through the pilot application.
