Abstract: A highly reliable and weatherproof microgrid system was designed under extreme climate conditions, including extremely cold, high winds and thin oxygen, at Taishan Station in Antarctica. The essential operating parameters and installation strategy of the multi-energy complementary microgrid system were studied and simulated using the environment of Taishan Station. The development of this system provides a breakthrough for key technologies, such as solar and wind power generation, capacity and design, under extreme climate conditions. Advances in design and operation, including snow protection and control system designs for a multi-energy complementary microgrid and an intelligent control platform that can operate autonomously, were first studied and applied. Through the use of two control modes (grid-connected and off-grid operation modes), an efficient, stable and complementary system, including wind, solar, fuel and storage, was constructed. The system was installed, debugged and tested at Taishan Station; the results showed that the system met the design requirements and calculation results and can be used as a reliable power supply for Antarctic research stations.
