A New Approach For Reliability Evaluation Of Interconnected Power Systems

Abstract

__Abstract: Itcli:hility of iiitcrcotiiieclctl power systciiis is aii important arca of itivcstigatioti. Otic of tlic iiiiportatit atialytical mctliotls is tlic ~ i~ i i i l t ancor i s DecoiitpositionSiinulrttioti (SiDcS) [5,G].. A major drawbnclt of SiDcS nictliod is tl int tlie clliciciicy of tlie decoiiipositioti process decrcnscs rapidly as the prolxibility of tlic scts gcts siiiallcr and sitinllcr. After a few ilmntioiis, tlie iiiiitibcr of statcs Ilcitig cl~ssifietl in soiiie of tlie arcs falls to just oiic state. Coitscq~ictit~ly, t,lic tiunibcr of sets being geiieratcd is very largc for a iiiotlcrat,c iiutiiber of arcas. The nuiiiber of sets generated lias serious iiiiplicatioiis ott tlic storage requirciiiciits atid frequency calculn(ioiis which dcpciids on tlic cxatnirintioti of sribsct ititcrscctioii.
