One of them means knowing the electrical status of the system more accurately and the second one knowing the real-time (dynamic) thermal ratings of the lines. The latter technology is already being applied At a number of utilities. Recommendation 27 of the Blackout Task Force recommended more uniform thermal rating procedures and "the application of dynamic ratings". The dynamic ratings allow more capability most of the time but also warn operators of potentially unsafe thermal conditions. There are two types of real time monitoring.

The terms you should be using are "real-time state estimation and real-time contingency analysis".
