Zusammenfassung:The invention belongs to the technical field of power grid operation and control, and particularly relates to a power distribution system normalization risk analysis method based on Latin hypercube random sampling, which comprises the following steps: establishing a distributed photovoltaic power supply output model, and determining random variables in the distributed photovoltaic power supply output model as illumination intensity and battery temperature; based on the distributed photovoltaic power supply output model, adopting a Latin hypercube random sampling method to carry out probability distribution sampling on temperature and illumination intensity parameters influencing the distributed photovoltaic power supply in different scenes, and generating a sample of the output power of the photovoltaic power station; the samples are accessed to a power distribution system to calculate probabilistic load flow distribution of the system; and analyzing the probabilistic power flow of the power distribution syst
