Value of the lost load (VOLL) is a useful quantity in economical evaluations of power systems. The VOLL depends on multiple factors such as type of customer, regional economic conditions and demographics, time and duration of outage, and other specific traits of power interruption. The reviewed literatures show that there are still issues which could be considered in estimation of the VOLL, especially for industrial customers. One of the most interesting issues is inclusion of reliability of an industrial plant in estimation of the VOLL. This means that how reliability data of the plant components (failure rates, repair time, etc.) can be incorporated in the studies to provide a probabilistic model for the VOLL and its related quantities. This paper incorporates failure probability in the VOLL estimation of an industrial plant. For this purpose, firstly an estimate for failure rate of the plant components is obtained and secondly, this estimate is applied in failure probability function which is to be incorporated in the VOLL. Results provide a probabilistic model for the VOLL.

考虑失效概率的损失载荷值

负载损失(VOLL)的值在电力系统的经济评估中非常有用。VOLL取决于多个因素,例如客户类型,区域经济状况和人口统计学,停电的时间和持续时间以及其他特殊的电源中断特征。回顾的文献表明,在估算VOLL时仍然存在一些需要考虑的问题,特别是对于工业客户。最有趣的问题之一是在估算VOLL时要包括工厂的可靠性。这意味着如何将工厂组件的可靠性数据(故障率,维修时间等)纳入研究,从而为VOLL及其相关数量提供概率模型。本文将故障概率纳入了工厂的VOLL估计中。以此目的,首先,获得工厂组件故障率的估计值;其次,将该估计值应用于故障概率函数,该函数将被合并到VOLL中。结果为VOLL提供了概率模型。
