Based on the information of power load survey and fault disturbing curves in North West Power Grid, some questions in terms of load parameters by means of aggregation of induction motors, simulation effects and determination of load parameters were solved.

This thesis expounds the theory and means about power system load modeling, introduces two method of load modeling, that is, Component-Based Modeling Approach and Measurement-Based Modeling Approach.

According to the pseudo linear combination structure of Volterra series model, by applying the principle of the total least squares identification, a total fully decoupled identification idea is revealed.
