The invention discloses a hybrid networking method based on power line broadband carrier. The method comprises the following steps: step (A): a hybrid networking architecture is established; step (B): an information security line of hybrid networking is established from five aspects of hybrid networking: terminal verification, communication encryption, authorization management, behavior audit and region isolation according to the hybrid networking architecture; and step (C): adaptive communication with a terminal access is constructed on the hybrid networking after the information security line is established. According to the hybrid networking method based on power line broadband carrier, the remote control function of the controllable loads of resident users can be enabled by hybrid networking; the shunt energy use data of the resident users and the switch running status are provided for an electricity utilization information collecting system; basic data is provided for big-data statistical analysis of the energy use habits of residential users; a technical support is provided for the interaction between power companies and the resident users and the publicity of energy-saving recommendations; and the method is suitable for promotion and has good application prospects.
