摘要：
With the increase of the complexity of cyber-physical system of the active distribution network, the evaluation efficiency of reliability has become the key factor which restricts its practical application, so a rapid assessment method of cyber-physical system is urgently needed. Based on the consideration of the cyber transmission performance, a new method is proposed for the rapid evaluation of cyber link validity based on frequency/time domain transformation, which provides a new way for quantizing the cyber transmission performance. Then, in order to quantify the indirect interdependencies of cyber failure on the self-healing of distribution network, the probability model for switch failure is established considering the cyber failure. Meanwhile, considering the multi-switch self-healing action of distribution network and combining the equivalent method and the minimal path method, an innovative calculation method is put forward for the average outage time in the upward equivalent process of network equivalence. Based on this, the reliability of various users in distribution network is calculated. Finally, a test system is established to verify the validity and effectiveness of the proposed method. The influence of the matching degree of cyber and physical elements on the reliability is discussed and the influence of cyber fault on the planned island and load transfer is analyzed. © 2019 Automation of Electric Power Systems Press.
