Abstract

A detailed EMTP model of a mixed residential-commercial load valid for large voltage variations has been developed. Once validated against field recordings, the model has been used to study the static, dynamic and post-fault recovery characteristics of the real load. From the simulation results, guidelines for modeling this type of load in dynamic studies such as first swing, transient and voltage stability were established. It is expected that the same methodology applied to other loads of reasonably known composition would guarantee more realistic results than those obtained with current practices
