This paper designs a new AC & DC hybrid power supply system for data centres, which includes photostatic power generation, wind power generation, solar thermal power generation, storage power systems, and different types of loads. According to the above‐mentioned, the paper first presents the reliability evaluation indicators and analysis methods applicable to the new AC & DC hybrid power supply system for data centres, which are for solving the problem of the reliability evaluation under uncertain parameters and load parameters of the new data centre power supply system. The paper describes the new power supply system reliability indicators and evaluation methods in detail. The problem of the power supply reliability in the new AC & DC hybrid power supply system in the data centre is analysed in a targeted manner by adopting actual examples, then it is verified that the power supply reliability of the new AC & DC hybrid power supply system can perfectly meet the qualification of the A‐class data centre power supply. The reliability of assessment index and analysis methods presented here will be two simple and superior analysing tools.
