Decentralized control method and system of distributed energy system integrating blockchain and 5g

Abstract

The invention discloses a decentralized control method and system of a distributed energy system integrating blockchain and 5G, and belongs to the field of distributed energy control. The existing Internet of Things communication data volume is generally large, and the communication speed is generally slow, so the existing blockchain technology cannot be directly applied. The invention provides a decentralized control method for a distributed energy system integrating blockchain and 5G. By constructing a deviation data transmission model, a fuzzy gray evaluation model, a 5G communication model, and a smart contract model, the difference between the collected data and the initialization data is calculated. The deviation amount, the deviation collection data is obtained, and only the difference between the collection data and the initialization data is transmitted, which can effectively reduce the amount of data transmission, reduce the communication delay, and realize the decentralized control of the distributed energy system; thus, the present invention can be applied to For distributed energy control scenarios with high latency requirements such as voltage control and frequency control, the solution is scientific, reasonable, and practical.

Description

technical field [0001] The invention relates to a decentralized control method and system for a distributed energy system integrating blockchain and 5G, and belongs to the field of distributed energy control. Background technique [0002] Distributed energy systems represented by microgrids and virtual power plants are developing rapidly. However, distributed energy information systems are relatively weak in network security protection, and the main body is scattered on the user side. Compared with traditional power grids, they are more vulnerable to network attacks. How to improve distributed energy control The anti-attack capability of the system is the current problem. [0003] At the same time, when the existing centralized system faces the problem of system failure, service interruption will inevitably occur. Even if there is a system backup, there are service interruption gaps, which cannot realize the real "multi-activity" of the system. [0004] Further, the Chinese...

Problems solved by technology

[0005] However, in the Internet of Things scenario, the amount of communication data is generally large, and the communication speed is generally slow; at the same time, the above scheme and the existing blockchain need frequent communication for consensus to ensure data consistency. Therefore, if the above scheme and the existing blockchain are directly applied With blockchain technology, it will further increase the latency of IoT scenarios, making it difficult to apply to distributed energy control scenarios that require high latency, such as voltage control and frequency control. As a result, blockchain cannot be used in distributed energy control systems. practical application
