According to the present status and the needs from the developments of power systems， the research tendencies of electric load modeling are pointed out in this paper. In the aspect of area scale， load modeling is developed from node scale to wide area. In the aspect of connotation， load modeling is developed from pure load to generalized load. In the aspect of model adaptation， load modeling is developed from small range to broad-spectrum. In the aspect of modeling methodologies， load modeling is developed from the single method to comprehensive methods. In the aspect of data resources， load modeling is developed from single data resource to multi data resources. Some detailed thoughts and proposals for load modeling research are also given in this paper.
