Chance-Constrained Economic Dispatch With Non-Gaussian Correlated Wind Power Uncertainty
TLDR
This paper provides a novel method dealing with non-Gaussian random variables in wind farm decision making as a chance-constrained economic dispatch problem that can be solved as a deterministic linear convex optimization with a global optimal solution.
Fast Screening of Vulnerable Transmission Lines in Power Grids: A PageRank-Based Approach
TLDR
A PageRank-based fast screening method is derived to identify VLs, and the concept of interaction graph is extended to model cascading outages as a directed weighted graph, where impacts of hidden failures are first taken into account.
A Distributed, Cooperative Frequency and Voltage Control for Microgrids
TLDR
A novel secondary frequency and voltage control method for islanded microgrids based on distributed cooperative control using a sparse communication network where each DG unit only requires local and its neighbors’ information to perform control actions.
A Jacobian-free Newton-GMRES(m) method with adaptive preconditioner and its application for power flow calculations
TLDR
The results show that the adaptive preconditionser can enhance convergence of Newton-GMRES(m) iteration schemes greatly and has stronger robustness compared with other precondition methods.
Feasible Range and Optimal Value of the Virtual Impedance for Droop-Based Control of Microgrids
This paper presents a systematic method to determine the feasible range and optimal value of the virtual impedance of the droop-based control to enhance a microgrid system performance with respect to
Risk-Limiting Load Restoration for Resilience Enhancement With Intermittent Energy Resources
TLDR
Results indicate that networked microgrids can perform better in uncertainty management relative to stand-alonemicrogrids.
An Adjustable Chance-Constrained Approach for Flexible Ramping Capacity Allocation
TLDR
A concept of conditional distributions of wind power ramping is proposed, which is empirically verified by using simulation and real-world data and an adjustable chance-constrained approach to optimally allocate FRC reserves is developed.
Fast Searching Strategy for Critical Cascading Paths Toward Blackouts
TLDR
An improved interaction graph is constructed to cope with the situation where the $(N-1)$ criterion is not satisfied during the follow-up cascade propagation after an initial fault, and a modified PageRank model is derived to fast rank the influence of individual transmission lines on blackout risks.
