Risk analysis of power information control system based on smart grid security standardization

Abstract

The smart grid has emerged to meet the rapidly increasing power demand and solve environmental problems through sustainable development. Advanced power networks are being developed to improve the efficiency of power system operation and energy utilization. The advancement of power networks enables us to collect power information in real time, build a database, and optimally control it by utilizing various applications of organically constructed energy management systems. Currently, the rapid change in power infrastructure necessitates security, and the establishment of a cyber security system is essential. Therefore, this paper analyzes the functions of the power information control systems and calculates the risk level for each component by applying the security risk estimation criteria in the Korean Smart Grid security standard (SGSF-121-1-1).
