Distributed Multi-Time Slot Power Balancing Control of Power Systems with Energy Storage Devices
Luwei Yang, Tao Liu, David J. Hill
This paper studies a crucial problem in power system balancing control, i.e., the multi-time slot economic dispatch (MTSED) problem, for power grids with substantial renewables, sy…
Chance Constrained Economic Dispatch Considering the Capability of Network Flexibility Against Renewable Uncertainties
Yue Song, Tao Liu, David J. Hill
This paper incorporates a continuous-type network flexibility into chance constrained economic dispatch (CCED). In the proposed model, both power generations and line susceptances…
Augmented Synchronization of Power Systems
Peng Yang, Feng Liu, Tao Liu +1
Power system transient stability has been translated into a Lyapunov stability problem of the post-disturbance equilibrium for decades. Despite substantial results, conventional th…
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…
Distributed Optimization With Event-triggered Communication via Input Feedforward Passivity
Mengmou Li, Lanlan Su, Tao Liu
In this work, we address the distributed optimization problem with event-triggered communication by the notion of input feedforward passivity (IFP). First, we analyze the distribut…
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…
Discrete-Time Distributed Observers over Jointly Connected Switching Networks and an Application
Tao Liu, Jie Huang
In this paper, we first establish an exponential stability result for a class of linear switched systems and then apply this result to show the existence of the distributed observe…
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…
Distributed Event-Triggered Control for Asymptotic Synchronization of Dynamical Networks
Tao Liu, Ming Cao, Claudio De Persis +1
This paper studies synchronization of dynamical networks with event-based communication. Firstly, two estimators are introduced into each node, one to estimate its own state, and t…
