“…To assess the ability of a complex engineering system to withstand cyberattacks, the concept of system vulnerability level is introduced, the numerical rating of which is a vulnerability index. In [36,37], the concept of the vulnerability index of the state estimation was introduced, with the latter characterizing the degree of exposure of its results to possible errors in measuring information when cyberattacks are directed at the SCADA system. A set of indicators descriptive of the accuracy of state estimation results was used to determine the vulnerability index.…”

The study deals with the cybersecurity concept of cyber-physical electric power systems (EPSs) as a strategic issue of national importance, which affects all strata of society. The link between the cybersecurity of EPSs and Russia's energy security and information security is analyzed. Data on the number of cyberattacks on control systems of industrial enterprises, power plants, and substations for several years are provided. The consequences of cyberattacks for the operability of the EPS physical subsystem and its facilities are analyzed. Areas of research to counteract external cyber threats are outlined. The key findings of the EPS cybersecurity study carried out at the Energy Systems Institute of Siberian Branch of the Russian Academy of Sciences (ESI SB RAS) are summarized.

“…In the third case, we can determine at which node a cyberattack occurred by the value and the components of objective function (1). To eliminate the consequences of these attacks, we propose duplicating the data with WAMS measurements in real time to obtain redundant measurements [9].…”

Development of Smart Grid involves the introduction of Wide Area Measurement System (WAMS), which provides the use of information, computing and digital technologies for measuring, transmitting and processing operating parameters when solving control problems. In this regard, the increased vulnerability to cyberattacks of the control system was noted. The control of Smart Grid includes monitoring, forecasting and planning of the system operation based on its Electric Power System state estimation results. Therefore, the goal of the paper is to develop a mathematical instrument to bad data detection under cyberattacks. Particular attention is paid to false data injection attacks which result in distortion of state variables estimates. The result of the research is an algorithm developed for state estimation based on the interior point method and test equation obtained by Crout matrix decomposition. The obtained results showed effectiveness of the algorithm in state estimation.
