Energy internet safety assessment method based on expert fuzzy preference

Abstract

The invention discloses an energy internet safety assessment method based on expert fuzzy preference, and the method comprises the steps: firstly building an energy internet safety assessment index set, and collecting the index data of each to-be-assessed energy internet; Forming a fuzzy decision matrix of energy internet security assessment according to fuzzy evaluation given by experts, and calculating a positive ideal solution and a negative ideal solution of the security assessment; then determining favorable values and adverse values of all the to-be-evaluated energy networks under all the indexes, and calculating favorable effect values and adverse consequence values of all the energy networks under all the indexes; A fuzzy entropy weight method is adopted to give the weight of eachsafety assessment index; And finally, weights given by experts under favorable and unfavorable conditions are calculated respectively, and safety assessment values of all energy internets are given. According to the invention, reference can be provided for planning construction and investment decision-making through safety assessment; And for the built energy internet, the discovery of the security weak link of the energy internet is facilitated, and the gradual improvement of the energy internet is promoted.

Description

technical field [0001] The invention relates to the technical field of energy internet, in particular to an energy internet security assessment method based on expert fuzzy preference. Background technique [0002] In the face of the global fossil energy depletion crisis and major concerns about environmental protection, the "Energy Internet" characterized by the deep integration of energy technology and information technology has received increasing attention. Energy Internet takes clean energy as the core of the power grid, couples other systems such as heat, natural gas and transportation, makes full use of advanced information technology, and interconnects a large number of distributed energy collection devices, storage devices and loads into a new energy network to realize system energy. and sharing of information. With the deep integration of energy system and information, the comprehensive security of energy physical system and information system has become a new res...

AI Technical Summary

Problems solved by technology

In addition, there are uncertainties in the factors that threaten the security of the Energy Internet, and the relationship between the factors is ambiguous. Only based on the objective evaluation calculation model has great limitations. We should make more use of the knowledge and experience of security evaluation experts to give a suitable Safety assessment method with fuzzy cognition and convenient assessment calculation
