Optimal Configuration of Comprehensive Power Supply System of Zhongshan Station in Antarctica Considering Low Temperature Characteristics of Batteries

In order to achieve the dual carbon goal and solve the problem of wind power consumption at the same time, this paper proposes a hybrid energy storage capacity optimization configuration method considering electric-hydrogen coupling for Zhongshan Station in South Pole. Firstly, the model of combined heat and power supply of hydrogen storage system with electrolytic cell, hydrogen storage tank and fuel cell is established to fully explore the potential of hydrogen storage system in combined heat and power supply. Secondly, considering the influence of temperature on battery capacity and charge-discharge characteristics, the relationship between battery capacity and temperature under the low temperature environment below 15°C was analyzed and studied, and mathematical modeling of battery capacity was carried out. Finally, a specific example of Zhongshan Station in Antarctica is solved and analyzed to verify the effectiveness of the proposed configuration method.
