Abstract: The uncertainty factors such as clean energy and electricity price have important influence on the planning and operation of power system.Distributionally robust optimization（DRO） method has received attention from researchers since it combines the advantages of stochastic optimization and robust optimization in dealing with uncertainties.This paper reviews the application of DRO method in power system.Firstly,the characteristics of DRO method are described,and it is compared and analyzed with other methods for coping with uncertainties.Secondly,the application status of different types of DRO methods in power system is introduced.Besides,advantages and disadvantages of various DRO methods are analyzed including two classes of probability density,moment information and distributed robust chance constrained method based on these two classes.Finally,the research directions of DRO method in the field of power system are summarized and prospected.
