Active power distribution network big data transmission method based on content filtering and multi-Agent cooperation

Abstract

The invention relates to an active power distribution network big data transmission method based on content filtering and multi-Agent cooperation. The method, based on a data sending party and a data receiving party, includes the steps: obtaining a content filtering model from the data sending party on the basis of an active power distribution network big data sample; determining, based on the content filtering model, whether to-be-sent active power distribution network big data is sensitive data, and processing the active power distribution network big data correspondingly through data self-protection marks; compressing and sending the processed to-be-sent active power distribution network big data; and decompressing the received data by the data receiving party according to a multi-Agent cooperation method, and thus obtaining active power distribution network big data. The entire method enables safe, reliable and highly efficient transmission of active power distribution network big data, and ensures that the active power distribution network big data is highly efficient and stale during transmission.

Description

technical field [0001] The invention relates to a large data transmission method of an active distribution network based on content filtering and multi-Agent cooperation, and belongs to the technical field of electric power information security. Background technique [0002] As an important part of the power system, the distribution network is one of the core contents of the smart grid construction. Especially in recent years, with the widespread access of multiple distributed equipment and components (such as microgrids, charging piles, etc.) units such as large-scale distributed energy, energy storage, and flexible loads, the distribution network is moving towards active power distribution. network development. Compared with the traditional distribution network, the composition of the active distribution network and the interaction between the source network and the load are more frequent and complex. With the popularization and application of application systems such as...

Problems solved by technology

[0003] With the extensive application of advanced information and communication technologies such as wireless communication and the Internet of Things in active distribution networks, the entire active distribution network is facing increasingly serious threats from viruses, Trojan horses, and hacker attacks from the Internet. Malicious attacks may also cause the control network of the entire active distribution network to collapse

However, the existing power secondary system safety protection schemes do not consider the security protection issues within the information communication network of the active distribution network and when interacting with the outside. With a more complex access environment, flexible and diverse access methods (such as GPRS, WiFi, and optical fiber communication, etc.), a large number of intelligent access terminals (such as various distributed energy information collection terminals, power distribution equipment and line operation status monitoring terminal, etc.) and dynamically distributed mass access data
