Terminal security access and data protection method based on virtual power plant

The invention discloses a terminal security access and data protection method based on a virtual power plant. The method comprises the following steps: S1, setting a plurality of virtual power plant substations according to the distribution condition of terminals aggregated by the virtual power plant; s2, a virtual power plant master station in the virtual power plant communicates with all virtual power plant substations through encryption; s3, sending an application to the virtual power plant master station and the virtual power plant substation at the same time when the terminal is accessed, and accessing the virtual power grid after both the virtual power plant master station and the virtual power plant substation pass the application; and S4, when the terminal transmits data, directly transmitting the segmented and encrypted data part to the virtual power plant master station, and transmitting the other part to the virtual power plant master station through the virtual power plant substation.
