摘要：
Based on the logical relationship of Bayesian network, specific to the uncertainty output power of distributed generation and time-varying characteristics of load in microgrid, the reliability indices of distribution system were solved by using time-sharing method. In the operation mode of island, the equivalent power (source) node was set with various logical combinations of distributed generation and energy storage elements, and with that, the "dynamic-supply" logical relation model was constructed for the supply-load node of the microgrid based on power flow calculation. The reliability of the modified RBTS Bus6-F4 was evaluated by the time-sequence simulation algorithm based on Bayesian network. With the help of Bayesian networks causal reasoning, the influence degree of each component reliability parameters on the system reliability index was analyzed, with the diagnosis reasoning, the fault condition probability of each element in the system was solved respectively in case of the system fault, the microgrid node fault and important or non-important load fault in microgrid. In turn, the key factors that influence the power supply reliability of important load were found out, and thus, the weak links of the system reliability were identified. © 2019 Chin. Soc. for Elec.
