Decentralized Frequency-Domain Conditions for D-Stability with Application to DC Microgrids
Zelin Sun, Shanshan Jiang, Xiaoyu Peng +3
This paper proposes a decentralized method for regional pole placement, or -stability, in linearized networked systems. Existing LMI-based methods are hindered by conf…
Frequency Security Assessment in Power Systems With High Penetration of Renewables Considering Spatio-Temporal Frequency Distribution
Changjun He, Hua Geng, Xiuqiang He +2
The increasing integration of renewable energy sources exacerbates the spatial and temporal differences in frequency across the power system, posing a serious challenge to the accu…
Decentralized Analysis Approach for Oscillation Damping in Grid-Forming and Grid-Following Heterogeneous Power Systems
Xiang Zhu, Xiuqiang He, Hongyang Qing +1
This letter proposes a decentralized local gain condition (LGC) to guarantee oscillation damping in inverter-based resource (IBR)-dominated power systems. The LGC constrains the dy…
Dynamic Virtual Power Plants with Robust Frequency Regulation Capability
Xiang Zhu, Hua Geng, Hongyang Qing +3
The rapid integration of inverter-based resources (IBRs) into power systems has identified frequency security challenges due to reduced inertia and increased load volatility. This…
