1. A method of simulating an electric power transmission network, comprising:
- assigning a parameterized value to an element in the network that is present during any time interval of a simulation test period;
if an element in the network has changed from a preceding time interval, updating the network of the preceding time interval by changing the parameterized value for the changed element; and
simulating the updated network.

Abstract
A method and system for efficiently simulating an electric power transmission network is disclosed. In the method, a parameterized value is assigned to an element in the network that is present during any time interval of a simulation test period. If an element in the network has changed from a preceding time interval, the network of the preceding time interval is updated by changing the parameterized value for the changed element, and the updated network is simulated. If any element in the network has not changed from the network of the preceding time interval, the network is simulated based on the network of the preceding time interval.
