The invention relates to a distribution network grid edge agent system which comprises a data acquisition module, an information processing module and a communication module. The data acquisition module is connected with the power distribution grid and acquires power distribution data; the information processing module is connected with the data acquisition module; data processing is performed based on the power distribution data; any one or a combination of more of a control adjustment instruction for the power distribution grid, a processing instruction for a fault in the power distributiongrid, early warning information for the fault in the power distribution grid and suggestion information for user power consumption in the power distribution grid are output so as to achieve any one ormore functions of grid autonomy, grid self-healing, defect early warning and energy consumption guidance; and the communication module is in communication connection with the information processing module, the power distribution grid and an Internet of Things management platform of the power distribution network to realize communication between the information processing module and the power distribution grid and between the information processing module and the Internet of Things management platform. According to the invention, through distributed and localized distribution grid management,reasonable and efficient management of the whole power distribution network is realized.
