This paper outlines the nature and characteristics of the transient response of a large stressed power network. Transient stability analysis of such a system by the transient energy function (TEF) method requires overcoming a number of analytical and numerical problems. These issues are identified and solutions to them are proposed. The procedure developed is tested on two realistic power networks derived from a large power flow base case of the Ontario Hydro system. Results of the tests compare well with time simulation and accurately predict the complex dynamic behavior.
