Convex Relaxation of AC Optimal Power Flow with Flexible Transmission Line Impedances
Yue Song, David J. Hill, Tao Liu +1
Flexible transmission line impedances on one hand are a promising control resource for facilitating grid flexibility, but on the other hand add much complexity to the concerned opt…
Impasse Surface of Differential-Algebraic Power System Models: An Interpretation Based on Admittance Matrices
Yue Song, David J. Hill, Tao Liu +1
The impasse surface is an important concept in the differential-algebraic equation (DAE) model of power systems, which is associated with short-term voltage collapse. This paper es…
Hierarchical Temporal and Spatial Clustering of Uncertain and Time-varying Load Models
Xinran Zhang, David J. Hill
Load modeling is difficult due to its uncertain and time-varying properties. Through the recently proposed ambient signals load modeling approach, these properties can be more freq…
Ensuring Network Connectedness in Optimal Transmission Switching Problems
Tong Han, Yue Song, David J. Hill
Network connectedness is indispensable for the normal operation of transmission networks. However, there still remains a lack of efficient constraints that can be directly added to…
Reducing BESS Capacity for Accommodating Renewables in Subtransmission Systems with Power Flow Routers
Tianlun Chen, Albert Y. S. Lam, Yue Song +1
Widespread utilization of renewable energy sources (RESs) in subtransmission systems causes serious problems on power quality, such as voltage violations, leading to significant cu…
Robust Transient Stability Constrained Optimal Power Flow with Power Flow Routers Considering Renewable Uncertainties
Tianlun Chen, Albert Y. S. Lam, Yue Song +1
This paper proposes a robust transient stability constrained optimal power flow problem that addresses renewable uncertainties by the coordination of generation re-dispatch and pow…
