Abstract：Focusing on the configuration optimization of energy storage equipment in the power supply system of large-scale data centers,taking the data centers in Tianjin area as the research object,the energy configuration situation is analyzed.The results show that when the installed capacity of wind turbines and photovoltaic power is less than 1 500 kW,it is not recommended to configure energy storage systems.Under different power supply modes,the function of the cold storage pool varies with the changes in the installed capacity of photovoltaic and wind power generation.When the installed capacity of photovoltaic or wind turbines exceeds a certain value,adding batteries can improve efficiency.When in the mixed configuration,when the installed capacity of both reaches 2 000 kW,the addition of the battery can also bring benefits.The cold storage tank can play an active role under specific installed capacity conditions.This research provides a reference for the planning of distributed energy systems in data centers,which helps to improve energy utilization efficiency,reduce carbon emissions,and promote the sustainable development of data centers.
