The Effect of the Uncertainty of Load and Renewable Generation on the Dynamic Voltage Stability Margin
Georgia Pierrou, Xiaozhe Wang
In this paper, the impact of stochastic load and renewable generation uncertainty on the dynamic voltage stability margin is studied. Stochastic trajectories describing the uncerta…
Online Measurement-Based Estimation of Dynamic System State Matrix in Ambient Conditions
Hao Sheng, Xiaozhe Wang
In this paper, a purely measurement-based method is proposed to estimate the dynamic system state matrix by applying the regression theorem of the multivariate Ornstein-Uhlenbeck p…
Investigating the Impacts of Stochastic Load Fluctuation on Dynamic Voltage Stability Margin Using Bifurcation Theory
Georgia Pierrou, Xiaozhe Wang
This paper studies the impacts of stochastic load fluctuations, namely the fluctuation intensity and the changing speed of load power, on the size of the voltage stability margin.…
Probabilistic Power Flow Calculation using Non-intrusive Low-rank Approximation Method
Hao Sheng, Xiaozhe Wang
In this paper, a novel non-intrusive probabilistic power flow (PPF) analysis method based on the low-rank approximation (LRA) is proposed, which can accurately and efficiently esti…
