摘要：The properties of electric power systems (EPSs) are currently in the process of digital transformation, which should be taken into account when controlling them. Despite the numerous advantages of the digital transition, there are still problems with quality of the data used to control the EPS, and they are to a greater extent associated with the cybersecurity threats to the EPS information and communication infrastructure. The paper demonstrates the effect of changes in cybersecurity properties of the information and communication infrastructure on the quality of data streams coming from SCADA and WAMS, and reveals their complex interaction. The need has arisen to assess the quality of data during cyberattacks on systems for collecting, transmitting and processing the information. An algorithm is proposed to assess the quality of measurements based on the fuzzy logic.
