An Autonomous Edge Control Method for Decentralized Smart Grid

Abstract

The invention discloses an autonomous edge control method oriented to a distributed smart grid. The steps include: 1. using a platform framework consisting of multiple mobile nodes, multiple terminal nodes and a cloud server; 2. using the mobile node as a transit connection terminal node and the cloud server; 3. The terminal node uploads data to the cloud server through the secure socket protocol, the transport layer security protocol and the link layer security protocol encrypted line; 4. If the connection is interrupted, the GPS position change of the mobile node is reacquired. The invention can improve the network security and data transmission efficiency of terminal nodes and cloud servers.

Description

technical field [0001] The invention relates to a distributed power grid, an intelligent edge device, and an autonomous control technology, in particular to an autonomous edge control method for a distributed smart grid. Background technique [0002] As distribution systems move toward decentralization, millions of devices, including transformers, capacitors, switches, PV inverters, and loads, need to coordinate with the grid to provide queryable status data, as facility classes vary significantly, traditionally Solutions suitable for power generation and transmission systems are not necessarily suitable for power distribution systems, which may be located in remote areas with poor connectivity, which makes connecting a large number of devices to cloud servers complex and expensive. [0003] The existing cloud connection method of power distribution system is based on a decentralized control method based on multi-layer intelligent communication, which adopts a platform cente...

Problems solved by technology

[0004] However, this method (that is, the existing method of connecting power distribution system facilities to the cloud) relies on the construction of infrastructure, and cannot efficiently deal with the remote geographical location and numerous equipment existing in the power distribution system. Therefore, the existing technology The method has many restrictions in practical application, the structure is complex, the cost is high, the return on investment is low, and there is a lack of rigorous security protection methods

[0005] The design of the connection method between the existing power distribution system facilities and the cloud server is not flexible enough, and different terminal devices and network base stations cannot be effectively compatible, requiring separate settings to increase time costs
