In the past, in electrical power networks, the effects on the system of particular contingencies, such as a given power line being interrupted, have been modelled off-line, so that the proper response to that contingency can be planned ahead of time and acted upon quickly in the event of such contingency. Such models have generally been overly conservative adding considerable cost to power systems. The present invention provides a method of predicting the transfer limit or the amount of remedial action required to maintain stability of a power system in the event of a study contingency by determining a transient energy margin, comprising the steps of:
