Optimal Control of a Stochastic Power System -- Algorithms and Mathematical Analysis
Zhen Wang, Kaihua Xi, Aijie Cheng +2
The considered optimal control problem of a stochastic power system, is to select the set of power supply vectors which infimizes the probability that the phase-angle differences o…
Control of the Power Flows of a Stochastic Power System
Zhen Wang, Kaihua Xi, Aijie Cheng +2
How to determine the vector of power supplies of a stochastic power system for the next short horizon, such that the probability is less than a prespecified value that any phase-an…
A Critical Escape Probability Formulation for Enhancing the Transient Stability of Power Systems with System Parameter Design
Xian Wu, Kaihua Xi, Aijie Cheng +2
For the enhancement of the transient stability of power systems, the key is to define a quantitative optimization formulation with system parameters as decision variables. In this…
Explicit formulas for the Variance of the State of a Linearized Power System driven by Gaussian stochastic disturbances
Xian Wu, Kaihua Xi, Aijie Cheng +3
We look into the fluctuations caused by disturbances in power systems. In the linearized system of the power systems, the disturbance is modeled by a Brownian motion process, and t…
Increasing the Synchronization Stability in Complex Networks
Xian Wu, Kaihua Xi, Aijie Cheng +2
We aim to increase the ability of a of coupled phase oscillators to maintain the synchronization when the system is affected by stochastic disturbances. We model the disturbances b…
Synchronization of Coupled Phase Oscillators with Stochastic Disturbances and the Cycle Space of the Graph
Kaihua Xi, Zhen Wang, Aijie Cheng +3
The synchronization stability of a complex network system of coupled phase oscillators is discussed. In case the network is affected by disturbances, a stochastic linearized system…
Synchronization of Power Systems under Stochastic Disturbances
Zhen Wang, Kaihua Xi, Aijie Cheng +4
The synchronization of power generators is an important condition for the proper functioning of a power system, in which the fluctuations in frequency and the phase angle differenc…
Transient Performance of Power Systems with Distributed Power-Imbalance Allocation Control
Kaihua Xi, Hai Xiang Lin, Jan H. van Schuppen
We investigate the sensitivity of the transient performance of power systems controlled by Distributed Power-Imbalance Allocation Control (DPIAC) on the parameters of the control l…
Multi-Level Power-Imbalance Allocation Control for Secondary Frequency Control of Power Systems
Kaihua Xi, Hai Xiang Lin, Chen Shen +1
A consensus-control-based multi-level control law named Multi-Level Power-Imbalance Allocation Control (MLPIAC) is presented for a large-scale power system partitioned into two or…
Power-Imbalance Allocation Control of Power Systems-Secondary Frequency Control
Kaihua Xi, Johan L. A. Dubbeldam, Hai Xiang Lin +1
The traditional secondary frequency control of power systems restores nominal frequency by steering Area Control Errors (ACEs) to zero. Existing methods are a form of integral cont…
Synchronization of cyclic power grids: equilibria and stability of the synchronous state
Kaihua Xi, Johan. L. A. Dubbeldam, Haixiang Lin
Synchronization is essential for proper functioning of the power grid. We investigate the synchronous state and its stability for a network with a cyclic topology and with the evol…
