The invention provides a method for evaluating the reliability of a wind farm having battery energy storage equipment. The method comprises the following steps of: acquiring original data of the wind farm; establishing a power time series model of a wind generation set; establishing an output power time series model having the battery energy storage equipment; establishing a wind farm reliability evaluation model having the battery energy storage equipment; establishing a reliability evaluation model in which operation characteristic parameters are considered; inputting acquired original data to a computer system for processing; and obtaining an wind farm reliability parameter in which the operation characteristic parameters of the battery energy storage equipment are considered. According to the method, the influence of the operation characteristic parameters of different types of battery energy storage equipment on the wind farm reliability is considered, so the accuracy of the reliability evaluation of the
