Abstract: Under the overall framework of the future lunar research station, the research status of the power system of foreign lunar research stations is investigated, and the power system capacity requirements of Chinese lunar research station are studied and analyzed; then the overall goal, construction stage and general idea of the energy system are put forward in this paper. The demand analysis is carried out according to the three stages of local capability improvement, comprehensive mission capability improvement, long-term maintenance and function expansion and the development concept of "integrated design, modular construction, intelligent operation and digital development" is proposed. According to the standard of "engineering verification, technological breakthrough, innovation leading", the energy technology is divided, and the solutions and development strategies in a targeted manner are put forward. The application scenarios are analyzed in turn for near-field or far-field wireless power transfer technology, high efficiency and lightweight thermoelectric conversion technology, nuclear reactor power generation and protection technology, large-scale energy storage array technology, fuel cell technology in space, system construction, lunar power grid system construction and management technology, etc. Then, the application index is put forward, and the implementation suggestions are given. On this basis, the conceptual ideas of large, medium and small power system are put forward, and they are briefly compared and analyzed.
