Abstract
The main objective of this paper is to evaluate the influence of load modeling, using the well-known ZIP model, in the steady-state analysis of electrical power systems. This evaluation is performed through the use of static security regions, which efficiently show the security conditions of different dispatches of generation groups, considering a constant demand. In the first part, this work presents the whole construction process of these regions in detail. Then, the use of load modeling is investigated by analyzing two systems. The first system, a small-scale tutorial system, is formed by 9 buses and the second one represents a simplified equivalent of the South Brazilian System, having 34 buses.
