Multi-attribute decision-making method for energy internet security assessment

Abstract

The invention discloses a multi-attribute decision-making method for energy internet security assessment, which comprises the following steps: firstly, establishing eight energy internet security assessment index sets from four aspects of natural disaster threats, network structure vulnerability, system equipment risks and information security threats, and collecting each index data to form an assessment decision-making matrix; determining the objective weight of each safety assessment index by adopting a standard deviation variation coefficient method; adopting a characteristic root method toobtain subjective weight of the multi-expert group, and calculating subjective and objective comprehensive weight of the safety assessment index; and finally, evaluating the safety level of the energy internet by adopting a comprehensive proportion evaluation method. The energy internet safety assessment index system is comprehensive. The assessment method has high operability, a given energy internet safety assessment result has high reference value, weak safety links and potential risk threats existing in energy internet construction can be found out, and the assessment method has positivesignificance in guaranteeing safe and stable operation of the energy internet.

Description

technical field [0001] The invention relates to the technical field of energy internet, in particular to a multi-attribute decision-making method for energy internet security assessment. Background technique [0002] Energy Internet construction is an important task of my country's energy production and revolution. As a complex energy-information coupling system, there are bound to be some unknown vulnerabilities and potential threats in the Energy Internet, which will affect the safe operation of the Energy Internet. Practice in recent years has shown that multi-energy coupling and deep information intervention have also led to new security issues such as large-scale power outages caused by damage to heat pumps and natural gas or misoperation of valves in my country, and blackouts in Ukraine caused by hacker attacks. In order to ensure the operational security of the Energy Internet, it is urgent to consider factors such as the natural environment, structure and equipment ...
