The cross space transmission of cyber risks in electric cyber-physical systems

The electric cyber-physical systems (ECPS) realize the deep integration and collaborative work between the cyber space and power system. But there also appeared a new security risk that the power system faults caused by cyber risks could seriously harm the ECPS stable operation. In order to explain the impact of cyber risks on ECPS, the following meaningful works have been done in this paper: firstly, the cyber risks and the cross space linkage interfaces have been clearly analyzed to elucidate the cross space conduction mechanism of cyber risks; Then, the existing form of cyber risks in power system and its harm have been assessed; finally, a field ECPS test environment has been constructed based on the 110kv smart substation simulation environment. A variety of power system faults caused by cyber risks have been simulated and its harm has been assessed.
