Comprehensive fault simulation method in active distribution network with the consideration of cyber security

With the many characteristics of cyber–physical systems (CPS), including complex evolution various dynamic processes in distribution networks (DNs), communication modes and serious network security events have become important issues. From perspective DN analysis, traditional electrical digital simulations cannot access current models cyber events. The interactions between physical be simulated analysed simultaneously, which is challenging to development CPS DNs. To evaluate impact on networks, a simulation platform that contains physical, control layers discussed. Three-phase short-circuit fault processing islanding operation are by data among three-layer used analyse tampering handling processes. influence false injection interception analysed. results show information has large protection control, leads expansion outage scope failure frequency adjustment. This article also provides basis for analysis identification prevention
