Abstract

Abstract:

With the development of smart grid and trans-region stability control technology, the information communication and the power system is being coupled more closely, and the security risk caused by cyber-attack is becoming higher and higher. As a key measurement and control channel, the E1 channel of the stability control system plays an important role for the security of stability control system. Thus, it is of significance to conduct the attack and defense drills on a hardware-in-the-loop simulation platform to find the security risk of E1 channel of the stability control system. Firstly, a cyber range testbed was designed for the E1 channel of the stability control system based on the hardware-in-the-loop simulation technology, and the scheme of attack and defense drills on the designed testbed was briefly introduced. Then, through the testbed, we simulated a case of a cyber-attack on the E1 channel of an operating power stability control system to test its security risk and validate effectiveness of the designed testbed. Finally, we proposed several solutions to improve the security of the E1 channel, and made a perspective of the future application of the designed testbed.
