The reliability analysis of protection systems in smart substations helps to improve their designed functions, whose difficulty lies in the complex configuration with various components. To avoid the dimension disaster, the state spaces of the protection systems may be aggregated to several lumped states. When the states do not satisfy the balance criterion, it is newly found that the lumped states...
A hybrid approach based on the pseudo-sequential sampling and the network-equivalence techniques is proposed for distribution system reliability evaluation in this paper. In pseudo-sequential sampling, a failure state is obtained based on the non sequential simulation at first, then the whole system interruption I(a set of successive failure states) is acquired by the forward/backward simulation associated...
