Emergency-Aware and Frequency-Constrained HVDC Planning for A Multi-Area Asynchronously Interconnected Grid
Yiliu He, Haiwang Zhong, Grant Ruan +2
High-voltage direct current (HVDC) technology has played a crucial role for long-distance transmission of renewable power generation. However, the integration of large-capacity HVD…
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…
Performance-Aware Control of Modular Batteries For Fast Frequency Response
Yutong He, Guangchun Ruan, Haiwang Zhong
Modular batteries can be aggregated to deliver frequency regulation services for power grids. Although utilizing the idle capacity of battery modules is financially attractive, it…
Temperature-Controlled Smart Charging for Electric Vehicles in Cold Climates
Grant Ruan, Munther A. Dahleh
The battery performance and lifespan of electric vehicles (EVs) degrade significantly in cold climates, requiring a considerable amount of energy to heat up the EV batteries. This…
