Field frequency data of three real event cases from SMD-Ls.
Case 1: a fast event.
At 17:21:31 on March 18, 2020, the second-line circuit breaker in Shanan, Jibei, China tripped. The valid SMD-L data points in the AC network of North China are in place H, Z, X, and N.
Case 2: a slow event.

Schematic diagram to illustrate the separation and identification of nonlinear flow characteristics for the proposed method. Due to a fact that steam turbines and generators have different dynamic characteristics at different operating points, the static nonlinear flow characteristic (e.g., yellow solid lines in (a)) is overwhelmed by input and output data with dynamic characteristics, such as the blue dots in (a) and their corresponding time series are shown in (b). The key to identifying the nonlinear flow characteristic is to separate it from the linear dynamic submodels at different ope

The mainstream battery pack voltages of electric vehicles (EVs) range from 200 V to 500 V. Compared with these conventional 400-V battery packs, 800-V EVs have smaller cables, higher charging power, and a longer range. Although existing literature has overcome the drawbacks caused by one or two parameter variations in a 400-V EV WPT system, few works discuss the Z classes, output voltages, and output power levels simultaneously.
