摘要：

Variance, in addition to the expected production cost and loss of load probability, can be a very useful index in production costing, especially in the context of power plant fuel management. Based on the load duration curve (LDC) and equivalent unit concepts, an efficient algorithm has been developed to evaluate the variances in both the system production cost as well as for each generating unit. The approach is different from previous work by Mazumdar and Yin, since it does not assume the LDC to be a probability function. It treats the LDC as a deterministic function of the load's duration time. While the algorithm uses the LDC, it does not depend on it. The algorithm can be easily extended to chronological loads when used together with the Z-transform method developed by Sutanto. Because the LDC is not assumed to be a probability function here, this approach does not overestimate the variances as do methods that interpret the LDC as a probability function of the load.
