Distribution system reliability cost/worth analysis usinganalytical and sequential simulation techniques

摘要

The requirements for extensive justification of new facilities andnemphasis on the optimization of system cost and reliability are steadilynincreasing. Customer interruption cost analysis provides valuable inputnto electric power supply reliability worth assessment. This papernpresents both a generalized analytical approach and a time sequentialnMonte Carlo simulation technique for evaluating the customerninterruption cost in complex radial distribution systems. Studies arenconducted on two practical distribution systems. The results obtainednusing the analytical technique incorporating average restoration timesnare compared with those obtained using the time sequential simulationnmethod and random restoration times. The effects on customerninterruption cost indices associated with alternate supply andnprotection devices are also considered
