Abstract: In order to support the diverse simulation needs of the power market, the functional architecture of the power market panoramic experiment platform is upgraded. A three-layer experiment system with the experiment platform, the experiment scene and the experiment example is proposed. By disassembling the function of the panoramic experimental platform covered by the whole commodity sequence of the electric power market, the functional component library of the experimental platform is formed after the independent encapsulation. According to the requirements of simulation objectives, the component elements can be flexibly selected to build the experimental scenes of the electric power market, then the model and data are configured to form various simulation examples for different scenes. Through the expansion and the combination of scenes, the tri-layer experimental system can improve the efficiency of the function adjustment and the platform use on the basis of supporting the requirements of the panoramic experiments. Furthermore, the operation mode of double expert system is proposed on the panoramic experiment platform of the electric power market, and four typical experiment scenes of the electric power market are specifically designed.
