Modeling of common load components in power system based on dynamic simulation experiments

Abstract

The subject of load modeling for bulk power system dynamic simulations has been received increasing attention in the past decades. The characteristics and models of the common load components are foundations to construct the accurate composite load models for power system dynamic stability studies. The power system common used load components, the load classes and the main load components in power system are introduced firstly. Then, the common used static load components, such as incandescent, fluorescent, sodium lamp, LCD, desktop pc, notebook, electromagnetic oven, microwave oven, electronic oven and auto rice cooker, are modeled based on dynamic simulation experiments. In order to ensure these models to be precise to simulate the actual dynamic responses of load components, large disturbance tests are adopted to validate these models. Comparisons of the proposed models and the typical models cited from influential references for common load components are done to justify the necessary of this work.
