A Security Management Mode of Electrical Power System Through Zero Web of Trust System

With the continuous growth of industrial field, the structure of electrical power system (EPS) is more diverse, and the boundary uncertainty is gradually increasing. In the dispatching work, the operation of EPS is adjusted and controlled by the operators. At the same time, under the basic condition of ensuring their personal safety, the operators need to follow the operation rules of EPS and various dispatching rules and regulations to the greatest extent. This article constructs an EPS security management model of network system based on zero trust, and puts forward a security application solution based on zero trust architecture, thus establishing a truly effective EPS information security architecture. The simulation results show that the error of the proposed algorithm can be stabilized at around 1.3; and the accuracy of the algorithm is as high as 95.76%, which is about 9.87% higher than the compared algorithm. The results show that this method is practical and reliable. The EPS security management mode based on zero trust proposed in this article can effectively reduce data security risks and improve data security and business security of EPS.
