Wind-storage-fire combined scheduling method and system capable of interrupting load, and storage medium

The invention discloses a wind-storage-fire combined scheduling method and system capable of interrupting a load, and a storage medium. The scheduling method comprises the following steps: S1, analyzing a wind power prediction error; S2, constructing a wind-storage-fire combined dispatching model: constructing an inner-layer model by taking the minimum wind-storage combined operation fluctuation standard deviation as a target, and constructing an outer-layer model by taking the daily income of a power generation enterprise under full wind power consumption of an interruptible load as a maximum target; S3, substituting the wind-storage combined operation output obtained through the inner-layer model into the outer-layer model, and obtaining the output of each unit meeting the spinning reserve of the system and a scheduling plan of an interruptible load participation system. According to the invention, the power supply end provides spinning reserve by using the pumped storage unit and the traditional unit, and
