The present invention belongs to the field of microgrid technology, and specifically relates to a microgrid cluster system based on single grid-connected power line connection and dynamic networking. Aiming at the distributed renewable energy application scenario of building multiple microgrid systems in one area, according to the main technical characteristics and networking characteristics of the microgrid and from the perspective of optimizing the top-level design, a single grid-connected power line L is used to connect with multiple decentralized independent microgrid systems through the grid access point LC and the grid switch GK, and the grid switch GK and the microgrid energy management system SEMS are controlled by the microgrid cluster energy management and control system GEMS to complete the dynamic networking and form the microgrid cluster system GM, realizing the dynamic connection of multiple decentralized independent microgrid systems and being able to flexibly and effectively control the overall operation and resource sharing of the microgrid cluster system, providing a feasible solution for the safe, reliable and efficient networking of the microgrid cluster system, which is beneficial to the application and development trend of distributed renewable energy.

The application relates to a device network access method and device and electronic equipment, wherein the device network access method comprises the following steps: scanning a first NFC tag of a to-be-network-accessed device to obtain device NFC information; scanning a second NFC tag corresponding to a position where the to-be-network-accessed device is located to obtain position NFC information; sending the device NFC information and the position NFC information to a cloud server, so that the cloud server performs network access verification based on the device NFC information, and when the to-be-network-accessed device passes the network access verification, the to-be-network-accessed device is connected to a network, and the device NFC information and the position NFC information are bound. According to the application, the safety of the device NFC information is guaranteed from the source by NFC technology, the to-be-network-accessed device is connected to the network only when the cloud server passes the network access verification, the to-be-network-accessed device is more safely connected to the network, the mapping between the device and the address is realized, the maintenance efficiency of the corresponding relationship between the device positions is improved, the accuracy of the corresponding relationship between the device and the address is improved, and the positioning efficiency of the device is improved.
