Abstract

Load modeling plays an important role in power system operation and control. With increasingly complex grid and emergence of various new load components, load modeling becomes an intractable task. In this paper, our research work will focus on load modeling at distribution level. In order to capture specific load characteristics of various load components, a complete load model at distribution level with equivalent capacitor, large motor and small motor is applied. Disturbance data is processed in advance through MATLAB programs according to the requirements of measurement-based approach. In case study, the measurements and simulated model outputs are demonstrated. For comparison purpose, three load models are used to access model accuracy, which are respectively complete load model at distribution level, composite load model at transmission level and dynamic load model in PowerFactory at distribution level. By contrast, the complete load model proved to have better performance in transient conditions. By splitting the induction motor into two parts, some issues are introduced at the same time. Future work will focus on the generalization capability of this compete load model.
