GARCIA SANCHEZ, Zaid; GONZALEZ-CUETO CRUZ, José Antonio; CASAS FERNANDEZ, Leonardo  and  BOZA VALERINO, Juan Gualberto. Modelling of the load for stable state studies of voltage stability. Energética [online]. 2013, vol.34, n.2, pp. 129-136. ISSN 1815-5901.

In this paper an analysis of the influence of the nature of the load is presented in the stability tension. The load margin is an exact indices to analyses voltage stability, however traditionally it has been considered the load for obtain these indices as a constant power load, this does not show faithfully the behavior of the load when the condition of tension in the electric system are deteriorate. It is demonstrated the influence of the load power factor in the obtaining of the maximum power load of the system, such as the influence of this one in the obtaining of the stability point and maximum load point. This paper presents software to obtain the load margin for on-line studies. The methodology was tested with IEEE test systems and a real system.

Keywords : load; voltage stability; critical point.
