This paper presents a non-linear model that characterizes the steady state behavior of a system through power balance equations derived for network users. In the formulation, a network user may be a particular generator or load, a power company, a bilateral or multilateral transaction or the pool. By means of a parameter variation, different models are employed to represent network users, starting with ideal current sources and evolving to ideal voltage sources. Currents and voltages allocated to every user vary according to the user modeling and are tracked throughout the parameter variation, providing means to determine the best representation for network users. Results for a 2-bus example and an equivalent of the Brazilian Southern Region system are presented and validated.
