Distribution systems fault analysis considering fault resistance estimation
(ELSEVIER SCI LTD, 2011)
Fault resistance is a critical component of electric power systems operation due to its stochastic nature. If not considered, this parameter may interfere in fault analysis studies. This paper presents an iterative fault ...
Effect of polishing techniques and time on surface roughness, hardness and microleakage of resin composite restorations
(Operative Dentistry IncIndianapolisÍndia, 2006)
An iterated sample construction with path relinking method: Application to switch allocation in electrical distribution networks
(2013-01-01)
We present a metaheuristic approach which combines constructive heuristics and local searches based on sampling with path relinking. Its effectiveness is demonstrated by an application to the problem of allocating switches ...
Multi-objective evolutionary algorithm for single and multiple fault service restoration in large-scale distribution systems
(ElsevierAmsterdam, 2014-05)
Network reconfiguration for service restoration (SR) in distribution systems is a complex optimization
problem. For large-scale distribution systems, it is computationally hard to find adequate SR plans in
real time since ...
Power System Observability Analysis Based on Gram Matrix and Minimum Norm Solution

Stability analysis of power systems described with detailed models by automatic method
(Elsevier B.V., 2009-05-01)
The power system stability analysis is approached taking into explicit account the dynamic performance of generators internal voltages and control devices. The proposed method is not a direct method in the usual sense since ...
On the use of Gram matrix in observability analysis
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
This letter presents some notes on the use of the Gram matrix in observability analysis. This matrix is constructed considering the rows of the measurement Jacobian matrix as vectors, and it can be employed in observability ...
Technology assessment for power quality mitigation devices - Micro-DVR case study
(ELSEVIER SCIENCE SA, 2011)
This work presents a case study on technology assessment for power quality improvement devices. A system compatibility test protocol for power quality mitigation devices was developed in order to evaluate the functionality ...
