Voltage Dependence Of Composite Loads In Power Systems

Abstract

This paper concerns the voltage dependence of composite loads in power systems. Based upon continuous field measurements by automatic monitoring devices, dynamic responses of typical system loads to sudden voltage changes have been obtained. The parameters of a load model have been evaluated from the field data, and their changes in a day and in a year have been presented for typical system loads. A constructive approach to synthesize load characteristics from load components has been discussed by comparing the synthesized load parameters with the measured ones.
