Complementing AC & DC Terminal Stability Analyses of MMC with Inner Loop Impedance

no code implementations8 Oct 2023 Chongbin Zhao, Qirong Jiang

Subsequently, an inner loop impedance for the circulating circuit is established, which considers the dynamics of public terminals and divides the injected voltage perturbation by the corresponding current perturbation at the same frequency.

New Perspectives and Systematic Approaches for Analyzing Negative Damping-Induced Sustained Oscillation

no code implementations19 Jun 2023 Chongbin Zhao, Qirong Jiang

This is because a) it can not cover the cases where hard limits are not triggered, and b) it can not provide a complete trajectory for authentic linear analysis to confirm the presence of SO.

Revisiting Nyquist-Like Impedance-Based Criteria for Converter-Based AC Systems

no code implementations16 Mar 2023 Chongbin Zhao, Qirong Jiang, Yixin Guo

Multiple types of Nyquist-like impedance-based criteria are utilized for the small-signal stability analysis of converter-based AC systems.

Real-time scheduling of renewable power systems through planning-based reinforcement learning

no code implementations9 Mar 2023 Shaohuai Liu, Jinbo Liu, Weirui Ye, Nan Yang, Guanglun Zhang, Haiwang Zhong, Chongqing Kang, Qirong Jiang, Xuri Song, Fangchun Di, Yang Gao

The well-trained scheduling agent significantly reduces renewable curtailment and load shedding, which are issues arising from traditional scheduling's reliance on inaccurate day-ahead forecasts.
