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…
On Extension of Effective Resistance with Application to Graph Laplacian Definiteness and Power Network Stability
Yue Song, David J. Hill, Tao Liu
This paper extends the definitions of effective resistance and effective conductance to characterize the overall relation (positive coupling or antagonism) between any two disjoint…
Distributed Inter-Area Oscillation Damping Control for Power Systems by Using Wind Generators and Load Aggregators
Zhiyuan Tang, Yue Song, Tao Liu +1
This paper investigates the potential of wind turbine generators (WTGs) and load aggregators (LAs) to provide supplementary damping control services for low frequency inter-area os…
Granular Optimal Load-Side Control of Power Systems with Electric Spring Aggregators
Congchong Zhang, Tao Liu, David J. Hill
To implement controllable loads for frequency regulation in transmission networks in a practical way, the control scheme needs to be granulated down at least to subtransmission net…
Generic Demand Model Considering the Impact of Prosumers for Future Grid Scenario Analysis
Hesamoddin Marzooghi, Shariq Riaz, Gregor Verbic +2
The increasing uptake of residential PV-battery systems is bound to significantly change demand patterns of future power systems and, consequently, their dynamic performance. In th…
Aggregated Demand Response Modelling for Future Grid Scenarios
Hesamoddin Marzooghi, Gregor Verbic, David J. Hill
With the increased penetration of intermittent renewable energy sources (RESs) in future grids (FGs), balancing between supply and demand will become more dependent on demand respo…
Aggregated Demand Modelling Including Distributed Generation, Storage and Demand Response
Hesamoddin Marzooghi, David J. Hill, Gregor Verbic
It is anticipated that penetration of renewable energy sources (RESs) in power systems will increase further in the next decades mainly due to environmental issues. In the long ter…
