Plug-and-play management method and system based on unified registration of power network devices

The invention provides a plug-and-play management method and system based on unified registration of power network devices. The method comprises the following steps: (1), generating a digital certificate of each power network device, and sending the digital certificates to the power network devices in an offline mode; (2), carrying out identity authentication on accessed power network devices according to the digital certificates, and after the identity authentication succeeds, carrying out valid device registration; (3), carrying out real-time dynamic monitoring on already registered power network devices; (4), arranging discovery and control authorities between the already registered power network devices; and (5), an already registered power network device A, within a discovery and control authority scope, discovering and controlling other already registered power network devices B of needed functions. According to the invention, through registration, discovery, description, control, event and display of all the power network devices, zero-configuration networking of automatic identification and automatic access of the power network devices and a system is realized.
