Transient Stability of Low-Inertia Power Systems with Inverter-Based Generation

no code implementations30 Nov 2021 Changjun He, Xiuqiang He, Hua Geng, Huadong Sun, Shiyun Xu

This criterion is proved to be a sufficient stability condition for addressing the effects of the jumps and cosine damping coefficient on the system stability.

Mode Clustering Based Dynamic Equivalent Modeling of Wind Farm for Small-Signal Stability Analysis

no code implementations17 Sep 2021 Xiuqiang He, Hua Geng, Geng Yang

It is deemed that a DEM can be used to represent the whole WF to evaluate its impact on the SSS of power systems, as long as the frequency response of the DEM adequately matches that of the detailed WF model around the frequency of oscillation modes of concern.

Transient Stability of Hybrid Power Systems Dominated by Different Types of Grid-Forming Devices

no code implementations22 Apr 2021 Xiuqiang He, Hua Geng

This paper investigates the transient stability of power systems co-dominated by different types of grid-forming (GFM) devices.

Synchronization Instability of Inverter-Based Generation During Asymmetrical Grid Faults

no code implementations20 Nov 2020 Xiuqiang He, Changjun He, Sisi Pan, Hua Geng, Feng Liu

In contrast, both positive- and negative-sequence synchronizations should be of concern for inverter-based generation (IBG) under asymmetrical faults.
