Decision-focused Conservation Voltage Reduction to Consider the Cascading Impact of Forecast Errors
Qintao Du, Ran Li, Weiyi Lv +3
Conservation Voltage Reduction (CVR) relies on the effective coordination of slow-acting devices, such as OLTCs and CBs, and fast-acting devices, such as SVGs and PV inverters, typ…
Distribution System Flexibility Characterization: A Network-Informed Data-Driven Approach
Qi Li, Jianzhe Liu, Bai Cui +2
A distribution system can flexibly adjust its substation-level power output by aggregating its local distributed energy resources (DERs). Due to DER and network constraints, charac…
Ensuring Transient Stability with Guaranteed Region of Attraction in DC Microgrids
Jianzhe Liu, Yichen Zhang, Antonio J. Conejo +1
DC microgrids have promising applications in renewable integration due to their better energy efficiency when connecting DC components. However, they might be unstable since many l…
Encoding Frequency Constraints in Preventive Unit Commitment Using Deep Learning with Region-of-Interest Active Sampling
Yichen Zhang, Hantao Cui, Jianzhe Liu +4
With the increasing penetration of renewable energy, frequency response and its security are of significant concerns for reliable power system operations. Frequency-constrained uni…
Deep Active Learning for Solvability Prediction in Power Systems
Yichen Zhang, Jianzhe Liu, Feng Qiu +2
Traditional methods for solvability region analysis can only have inner approximations with inconclusive conservatism. Machine learning methods have been proposed to approach the r…
Attack Identification and Correction for PMU GPS Spoofing in Unbalanced Distribution Systems
Ying Zhang, Jianhui Wang, Jianzhe Liu
Due to the vulnerability of civilian global positioning system (GPS) signals, the accuracy of phasor measurement units (PMUs) can be greatly compromised by GPS spoofing attacks (GS…
