Disclosed in the embodiments of the present application are a load shedding test method and apparatus for a pumped storage unit, and a device and a medium. The method comprises: determining probability distribution models of at least one known random variable corresponding to a target pumped storage unit, and determining an origin moment of a target random variable according to the probability distribution models; determining each order of semi-invariant of the target random variable according to the origin moment of the target random variable; determining a probability density function of the target random variable according to each order of semi-invariant, and determining an overall offset risk value of the target random variable; and determining a target function according to the overall offset risk value, and determining a target decision variable combination in a load shedding test for the target pumped storage unit, so as to perform the load shedding test on the target pumped storage unit.
