In order to ensure that the edge gateway meets the requirement of network safety protection of power grid dispatching automation in the process of intelligently accessing the power dispatching server, before the edge gateway accesses the power dispatching server, the distributed resource body uploads relevant information (namely first gateway hardware information) of the edge gateway connected with the distributed resource body to the power dispatching server after the main body construction is completed.
And after receiving the gateway access application, the power dispatching server extracts the second gateway hardware information from the gateway access application. And storing the second gateway hardware information and the gateway configuration information so as to authenticate the edge gateway subsequently.

In step 710 of some embodiments, after monitoring the activated communication port, the power scheduling server verifies the communication port according to the network security management rule to obtain a verification result. And when the verification result shows that the edge gateway is legal, establishing a preliminary communication link with the edge gateway.
The preliminary communication link refers to the preliminary connection established between the power dispatching server and the edge gateway, which is equivalent to the initial handshake, and the subsequent authentication is performed on the edge gateway, so as to judge whether the edge gateway has the right to access the power dispatching server.
In step 712, the edge gateway sends the first gateway hardware information to the power dispatching server.
And 714, the power dispatching server authenticates the edge gateway according to the first gateway hardware information and the stored second gateway hardware information.
In step 716, if the authentication is passed, the power dispatching server establishes a complete communication link with the edge gateway, so that the edge gateway is accessed to the power dispatching server.
In step 716 of some embodiments, the complete communication link refers to a complete connection established between the power dispatching server and the edge gateway, and after the complete connection is established, the power dispatching server can receive data sent by the edge gateway and can also send control signals and the like to the edge gateway.
When the authentication is passed, the edge gateway is indicated to have the right of accessing the power dispatching server, and at the moment, the power dispatching server establishes a complete communication link with the edge gateway, so that the power dispatching server is accessed into the edge gateway.
In step 718, the power grid monitoring model refers to a model used by the power scheduling server to monitor all distributed resources, including the distributed resource model and the graph file reported by each accessed edge gateway. The database table refers to the corresponding relation among the edge gateway, the distributed resource body, the distributed resource model, the graphic file and the power grid monitoring model. The monitoring data refers to data acquired by the edge gateway on the distributed resources. The distributed resource model refers to model data corresponding to distributed resources connected to the edge gateway. A distributed resource graph file refers to graph data corresponding to a distributed resource connected to an edge gateway.
And 720, the power dispatching server receives the distributed resource model and the graphic file reported by the edge gateway, imports the distributed resource model and the graphic file into the power grid monitoring model, and establishes a database table according to the distributed resource model, the graphic file and the power grid monitoring model.
In step 720, the database table refers to the corresponding relationship between the edge gateway, the distributed resource entity, the distributed resource model, the graph file, and the power grid monitoring model.
And step 722, the power dispatching server receives the monitoring data reported by the edge gateway, associates the monitoring data with the database table, and monitors the distributed resource according to the database table, the power grid monitoring model and the monitoring data.
The monitoring data and the database table established in the previous step are correlated, so that the monitoring data uploaded by the edge gateway can correspond to the distributed resource model and the graphic file, and monitoring and management of the power dispatching server are facilitated.
