An Adaptive-Importance-Sampling-Enhanced Bayesian Approach for Topology Estimation in an Unbalanced Power Distribution System
Yijun Xu, Jaber Valinejad, Mert Korkali +4
The reliable operation of a power distribution system relies on a good prior knowledge of its topology and its system state. Although crucial, due to the lack of direct monitoring…
Probabilistic Load-Margin Assessment using Vine Copula and Gaussian Process Emulation
Yijun Xu, Kiran Karra, Lamine Mili +3
The increasing penetration of renewable energy along with the variations of the loads bring large uncertainties in the power system states that are threatening the security of powe…
Hierarchical Interactive Architecture based on Coalition Formation for Neighborhood System Decision Making
Jaber Valinejad, Mousa Marzband, Mert Korkali +2
In recent years, significant efforts for improving the technical and the economic performance of smart grids have been applied with the presence of different players making decisio…
Uncertainty Quantification in Stochastic Economic Dispatch using Gaussian Process Emulation
Zhixiong Hu, Yijun Xu, Mert Korkali +3
The increasing penetration of renewable energy resources in power systems, represented as random processes, converts the traditional deterministic economic dispatch problem into a…
Power Distribution System Synchrophasors with Non-Gaussian Errors: Real-World Measurements and Analysis
Can Huang, Charanraj A. Thimmisetty, Xiao Chen +6
This letter studies the synchrophasor measurement error of electric power distribution systems with on-line and off-line measurements using graphical and numerical tests. It demons…
