Aggregation of Induction Motors in a Power System Based on Some Special Operating Conditions

This paper presents a simple method for aggregating three-phase double-cage rotor induction motors connected to a common bus based on their equivalent circuits in power system studies. It is simple to aggregate the motors based on their equivalent circuits under certain operating conditions. The proposed method has been directly derived from the equivalent circuits of motors at a same bus when their slips are unity or very small. The paper presents the derivation of the proposed technique and gives its verification.
