Application of internal point methods in cybersecurity problems of intelligent energy systems

Abstract

The paper considers approaches to the creation of intelligent energy systems based on WAMS monitoring systems, using information technology in metrology, in the means of receiving, processing and transmitting information and determining parameters in control tasks. The paper analyzes the existing cyberattacks on the SCADA and WAMS system and considers possible ways to solve control problems in terms of information security violations of intelligent energy systems. DoS-attacks are considered in more detail, which lead to the failure of devices that measure currents, voltages and capacities, as well as to the disruption of information processing equipment. The paper proposes an algorithm for estimating the state of cyber defense of the intelligent energy system based on mathematical modeling of the internal states of the system, which allows to obtain the required accuracy of calculations in terms of incomplete information, which is the inability to access measurement data.
