\[LC_i^P=(P_d^{p\max}-P_d^{i,p})C_d\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \left(10\right)\]
While \(P\) is maximum vector of demand in \(Pth\) year in (MW), \(P_d^{i,p}\) is provided load vector after failure of line \(i\) in \(Pth\) year of planning in (MW) , \(C_d\) is the load deficiency vector due to failure of line \(i\) in \(Pth\) year in (MW) , \(LC_i^p\)is load deficiency cost due to failure of line \(i\) in \(Pth\) year in ($/h) . Load deficiency cost due to failure of all lines in \(Pth\) year has been calculated as follows:
\[TLC^P=\sum_{i=1}^{N_i^P}LC_i^P=\sum_{i=1}^{N_i^P}\left(P_d^{p\max}-P_d^{i,p}\right)C_d\ \ \ \left(11\right)\]
