Reliability Evaluation of Cyber Physical System Based On Fast Analytic Method

With deepening research of Active Distribution Network (ADN), the reliability calculation efficiency of cyber physical system (CPS) has become a key factor restricting its practicality, so a fast evaluation method is urgently needed. This paper proposes a fast method to calculate the cyber link validity considering the transmission efficiency. The failure probability of cyber link is superimposed on the rejection rate of switching in distribution network. The switches model considering cyber failure is established and the reliability of distribution CPS under cyber failure is calculated.
