PMUs optimized allocation using a tabu search algorithm for fault location in electric power distribution system
(2004-12-01)
Phasor Measurement Units (PMUs) optimized allocation allows control, monitoring and accurate operation of electric power distribution systems, improving reliability and service quality. Good quality and considerable results ...
HPF boost interleaved operating in discontinuous conduction mode for trolleybus application
(2009-12-01)
This paper deals with results of a research and development (R&D) project in cooperation with Electric Power Distribution Company in São Paulo (Brazil) regarding the development and experimental analysis of a new concept ...
Electrical consumers data clustering through optimum-path forest
(2011-12-21)
Non-technical losses identification has been paramount in the last decade. Since we have datasets with hundreds of legal and illegal profiles, one may have a method to group data into subprofiles in order to minimize the ...
On the efficiency of an alternative codification for multiobjective service restoration in electric distribution networks
(2009-12-01)
This paper proposes an alternative codification to solve the service restoration in electric power distribution networks using a SPEA2 multiobjective evolutionary algorithm, assuming the minimization of both the load not ...
AC-DC three-phase multipulse converter with boost DC-DC stage and constant hysteresis control
(2011-12-28)
This work proposes a new three-phase multipulse rectifier based on the delta autotransformer connection with DC-DC Boost stages and constant hysteresis control which has the objective of providing a reliable DC bus for ...
Optimal power flow via interior-exterior method
(2007-12-01)
This paper presents a new approach to the resolution of the Optimal Power Flow problem. In this approach the inequality constraints are treated by the Modified Barrier and Primal-Dual Logarithmic Barrier methods. The ...
Transmission Expansion Planning Via a Constructive Heuristic Algorithm in Restructured Electricity Industry
(Ieee, 2013-01-01)
The transmission expansion planning problem in modern power systems is a large-scale, mixed-integer, nonlinear and non-convex problem. this paper presents a new mathematical model and a constructive heuristic algorithm ...
Identification of transmission line parameters from temporal measurements of currents and voltages in their terminals: Influence oh the length line
(2012-12-11)
The objective of this paper is to show a methodology to estimate transmission line parameters. The method is applied in a single-phase transmission line using the method of least squares. In this method the longitudinal ...
