Load representation for steady-state voltage stability studies

This paper presents new models for representation of different load types in steady-state voltage stability studies. The models are derived from the available measured characteristics of the power system loads. Special attention is paid to the induction motor load, with different mechanical loading as well as for special large loads such as aluminum smelter plants and are furnaces loads. Comparisons between results from the known models and the developed models are made and the necessity for using these developed models are put forward. It is also proved that erroneous results will be obtained using known available models of these loads. (C) 1997 Elsevier Science S.A.
