This paper proposes a modeling in constant power of the unbalanced TIM starting using Genetic Algorithm (GA) and AWM short-circuit based on their statics characteristics curves. The proposed models are compared with the conventional models in the literature. The results showed the good performance of the proposed models, allowing a more precise analysis of the real requests of these loads.2241-2248porTIMUnbalanced StartingAWMShort-CircuitConstant Power ModelingArtigo10.1109/TLA.2012.6418128WOS:000314170800007Acesso restrito0614021283361265
