WGAN-GP Model Framework. (IMAGE) Engineering Caption Under given scenario, accident type, and clearance time, calculate the first critical point and obtain the initial operating area. Then space division method is promoted to compress search space for calculating a small training set of critical points just in the critical operating area. Additionally, WGAN-GP model is utilized to fast-generate numerous critical points in the critical operating area by learning the data distribution of the set of critical points. Finally, the PDSR boundary with HPs is fitted by the least square method. Credit Yanli Liu et al. Usage Restrictions Credit must be given to the creator.
