Abstract: Taking a mountain stadium as the measurement object to study the capacity configuration of the regional energy supply system suitable for multi-energy scenarios. Energy use scenarios such as competitions,training and vacation are set considering future competition use and operations after the competition. The regional energy supply and demand system is established by using literature research,field visits,digital simulation and other methods. The results show that the average power consumption ratio of each scenario is 99.1%. The stadium uses photovoltaic power and wind power as the source of power supply,and the photovoltaic modules are arranged on the east and south sloping roofs,and the proportion of solar photovoltaic modules on the roof is 100% of the horizontal projection area of the entire roof. The energy storage capacity of the venue is 37952 kWh,and the effective energy storage is 12651 kWh.
