PROCESSING OF SYNCHRONOUS PHASOR MEASUREMENTS BY FUZZY LOGIC METHODS IN THE CASE OF CYBERATTACKS ON INFORMATION-COMMUNICATION INFRASTRUCTURE OF A CYBER-PHYSICAL ELECTRIC POWER SYSTEM
The use of intelligent and digital technologies in systems for measuring, transmitting, and processing information, which are part of the information-communication infrastructure, is aimed at improving the efficiency of EPS management. At the same time, with the EPS digitalization, there has been a rise in vulnerabilities to cyberattacks. In this context, the urgency of providing timely, complete, and reliable data to perform control in the case of cyberattacks is increasing. We propose an algorithm to process synchronized vector measurements based on wavelet analysis and fuzzy logic, which improves the quality of information used in the state estimation of electric power systems.
