摘要
A short-term reliability evaluation is used for power stations,where each power generating unit is presented by a multi-state Markov model.The main obstacle for reliability evaluation in such a case is a“curse of dimensionality”—a great(huge)number of states of entire power station that should be analyzed.A modern approach is proposed based on using Lz-transform that drastically simplifies computation.The proposed approach is useful for power system security analysis and short-term operating decisions.In order to illustrate the proposed approach,the short-term reliability evaluation for a power station with different coal fired generating units is presented.
