Pre-Fault Voltage Discrimination and Time-Domain Protection for Distribution Networks with Inverter-Based Resources
Junyuan Zhao, François Bouffard, Géza Joós
The increasing proliferation of inverter-based resources (IBRs) in distribution networks is presenting a major challenge for phasor-based overcurrent protection. This challenge ste…
Data-Driven Privacy-Preserving Modeling and Frequency Regulation with Aggregated Electric Vehicles via Bilinear Hidden Markov Model
Yiping Liu, Xiaozhe Wang, Geza Joos
Vehicle-to-Grid (V2G) technology allows bidirectional power flow for real-time grid support, making electric vehicles (EVs) well-suited for ancillary services such as frequency reg…
A Data-Driven Forced Oscillation Locating Method for Power Systems with Inverter-Based Resources
Yaojie Cai, Georgia Pierrou, Xiaozhe Wang +1
Forced Oscillations (FO) stemming from external periodic disturbances threaten power system security and stability. The increasing penetration of Inverter-Based Resources(IBRs) fur…
An Extended State Space Model of Aggregated Electric Vehicles for Flexibility Estimation and Power Control
Yiping Liu, Xiaozhe Wang, Geza Joos
The increasing penetration of electric vehicles (EVs) can provide substantial electricity to the grid, supporting the grids' stability. The state space model (SSM) has been propose…
