The application of connection number on generation system reliability assessment

Abstract

Generation system reliability assessment not only has its macro-certain factor, but also has its uncertain factor. Uncertainty factor gets reliability parameters fluctuating around its expectation. The connection mathematics, developed from the set pair analysis, can well deal with the macro-certain factor and the uncertain factor in power system generation reliability assessment. The connection number is applied for generation system reliability assessment in this paper. The identical-discrepancy connection number (IDCN) is used to represent reliability parameters. Quantitative method of reliability evaluation, based on the state space method, is used to evaluate generation adequacy of power system. IEEE-RTS79 generation system is assessed and the result is discussed. The method suggested in this paper gives a new idea to deal with the uncertainty of parameters in reliability evaluation of power system. © Springer-Verlag 2012.
