Robustness Analysis of CPPS considering Power Flow Constraints

Comprehensively considering the power flow constraints of network, cyber-physical system (CPPS) network integration model is established by combining with topological structure information and network. The Newton–Raphson method used to solve AC distribution in Based on interdependent theory, a CPPS cascading fault analysis procedure given. Finally, importance nodes evaluated analyzed. Simulation experiments are carried out IEEE39 node as an example. results show that some electrical components failures may lead large-scale transfer flow, resulting overloading other or transmission lines. It promotes further cascade propagation which eventually leads sharp decrease robustness CPPS.
