Abstract

A novel load modeling method based on characteristics fusion is proposed in this paper. First, for utilizing fully the information of the individual component devices and representing adaptively the change of the model structure of the composite load bus, the basic characteristics of the composite load bus, including the static, dynamic, withdrawing, and restarting characteristics, are obtained based on the typical load devices. To employ the measurement information adequately, the composite load mode is established by fusing the basic characteristics according to the recorded measurements during the system disturbances. The support vector regression (SVR) is used as a fusion tool due to its excellent performance. The simulation results demonstrate the effectiveness of the proposed method in the end.
