Assume that all transmission lines LOW and HIGH limitation capacity is limited to 70MW. Given the initial transmission system loading on line 1-2 as 48 MW and line 1-5 as 68 MW, LODF1-2, 1-5 = 0.3913, PTDF1.5, 1-2 = 0.1195. Calculate contingency flow on line 1-2 due to increase of power flow of 50 MW in line 1-5 and indicate if the line will be overloaded or not.
