摘要：

Aiming at time-varying feature of short-term reliability and redundant feature of communication system in islanded microgrid under master-slave control, a short-term reliability assessment method based on time-varying dynamic fault tree is proposed in this paper. Firstly, the time-varying dynamic fault tree is defined, and solution procedures of dynamic sub-tree and static sub-tree are presented. Then, direct and indirect events are defined and probability calculation is performed under the premise on load interruption of buses being regarded as a top event. On this basis, loss of load probability and expected demand not supplied by the microgrid are calculated and reliability assessment procedure is given. The proposed method is tested in an example to verify its correctness and effectiveness. The assessment results can provide some references for dispatching and operation of islanded microgrid under master-slave control. © 2018, Power System Technology Press. All right reserved.
