Abstract: As an important infrastructure for the country’s economic development, the power system, once the relevant grid production and enterprise management information is leaked or falsified, will inevitably cause significant losses to residents' electricity use and even national information security. Quantum security communication is based on the basic principles of quantum mechanics and has theoretical unconditional security. It provides a theoretically absolutely secure information channel for the safe transmission of grid production and operational data. This paper introduces the development status of quantum secure communication technology and its application in power systems, and analyzes the problems and challenges of
current quantum security communication technology in power system applications. Aiming at the main problems, this paper focuses on the key technologies of power quantum security communication, and prospects the future development and application mode of power quantum security communication technology, which can provide reference for the quantum security communication technology in thepower industry.
