Repeat Problem 5.53, but now assume any two line segments may be out of service.

Problem 5.53

Open PowerWorld Simulator case Example 5_8. If the load bus voltage is greater than or equal to $730kV$ even with any line segment out of service, what is the maximum amount of real power that can be delivered to the load?

Example 5_8

Can five instead of six 765 kV lines transmit the required power in Example 5.7 if there are two intermediate substations that divide each line into three 167-km line sections, and if only one line section is out of service?
