Anti-attack mechanism of novel power grid multi-defense system

Abstract

The invention discloses an anti-attack mechanism of a novel power grid multi-defense system. The anti-attack mechanism comprises a wisdom distributed energy management cloud platform, a data center, amicrogrid energy management unit, an energy storage module, an environment-friendly power generation module, a defense algorithm module, a data reputation evaluation module, a data reputation analysis module, a data collection unit, a storage module and an intelligent distribution network terminal. The wisdom distributed energy management cloud platform is in interactive connection with the datacenter, the data center is connected with the defense algorithm module, the storage module and the intelligent distribution network terminal, the defense algorithm module is connected with the data reputation evaluation module, and the data reputation evaluation module is connected with the data reputation analysis module. The purpose of preventing malicious intelligent terminal attacks is achieved through the reputation evaluation mechanism, the reputation mechanism is combined with intelligent terminal communication behaviors, and the credibility of the intelligent terminal is evaluated through direct reputation and indirect reputation, so the malicious intelligent terminal is isolated, and safe operation of a defense system is guaranteed.

Description

Technical field: [0001] The invention relates to the technical field of power grid defense, in particular to an anti-attack mechanism of a novel power grid multiple defense system. Background technique: [0002] With the progress of the economy and society and the wide application of advanced communication and information technologies, intelligence has become a new trend in the development of defense systems. The defense system has the characteristics of informatization, automation, and interaction, and the two-way interaction with intelligent terminals is enhanced. The access of a large number of intelligent terminals brings more risks to the defense system and poses new security issues for the development of the defense system. How to ensure the safe and reliable operation of the defense system, especially to prevent the attack and damage of malicious smart terminals, so as to realize the optimal allocation of distribution network resources, efficient utilization, comprehe...

Problems solved by technology

This improves the security of the defense system to a certain extent and reduces its security risks. However, after identity authentication, the intelligent terminal is trusted and interacted, and the internal malicious intelligent terminal, internal controlled intelligent terminal and external malicious intelligent terminal are not realized.
