Security is one of the most important properties of electric power system (EPS). We consider the state esti-mation tool as a barrier to the corruption of data on current operating conditions of the EPS. An algorithm for a two-level state estimation on the basis of SCADA and WAMS measurements is effective in terms of detec-tion of malicious attacks on energy system. The article suggests a methodology to identify cyberattacks on SCADA and WAMS.
