This study reviewed the current research progress of load modeling and pointed out the new circumstances faced by the load modeling. Then, this study put forward a research framework for the generalized synthesis electric load modeling containing active loads and discussed the research scheme in detail. The proposed research framework focuses on solving two key scientific problems, one of which is the coordination of the accuracy and conciseness for the model structure of active loads, and another is the coordination of the time variation and robustness for the parameters of load model. Thus, this study indicates a feasible technical route for building an accurate generalized synthesis electric load model considering the electrical characteristics of active loads.
