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…
Energy Control of Grid-forming Energy Storage based on Bandwidth Separation Principle
Chu Sun, Syed Qaseem Ali, Geza Joos
The reduced inertia in power system introduces more operation risks and challenges to frequency regulation. The existing virtual inertia and frequency support control are restricte…
Local Cold Load Pick-up Estimation Using Customer Energy Consumption Measurements
Sanja Bajic, François Bouffard, Hannah Michalska +1
Thermostatically-controlled loads have a significant impact on electricity demand after service is restored following an outage, a phenomenon known as cold load pick-up (CLPU). Act…
