Customer Interruption Cost Based on Hidden Failure of Power System Leading to Cascading Collapse

摘要

This paper proposes a systematic approach to calculate the customer interruption cost due to the effect of hidden failure in a power system. The distribution of electrical energy from the generation to the consumer might experience interruption due to some specific reasons. One of the reasons that could give catastrophic impact to the system is due to cascading collapse that might happen in the system. In this paper, the reliability cost from the customer's perspective being conducted in order to analyse the interruption cost based on cascading collapse. The analysis has been carried out from some sectors of the building that use the source of energy. Analysis has been made by using IEEE Reliability Test System 1979 (IEEE RTS-79) in order to verify the proposed technique is accurate. The total loading condition of the system have been calculated for this analysis in order to investigate the reliability cost towards the customers based on the interruption cost. The average probability of system cascading collapse and interruption cost of the failure shows a great impact to the consumer if the system is collapsed.
