Whereas, the number of suggested lines is different in various answers, average of equation (11) has to calculate. Thus, average of load deficiency cost due to failure of all lines in \(Pth\) year is computed as below:
\[ALC^P=\frac{(TLC^P)}{N_i^P}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \left(12\right)\]
Average present value of load deficiency cost during the planning horizon can be calculated as follows:
\[ALC^k=\sum_{p-1}^{np}\frac{ALC^p}{\left(1+r\right)^{p-1}}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \left(13\right)\]
