Integrated planning of electric power distribution networks
(2009-12-01)
In this work, a heuristic model for integrated planning of primary distribution network and secondary distribution circuits is proposed. A Tabu Search (TS) algorithm is employed to solve the planning of primary distribution ...
Placement and sizing evaluation of distributed generation in electric power systems
(2009-11-27)
This paper presents a methodology for the placement and sizing evaluation of distributed generation (DG) in electric power systems. The candidate locations for DG placement are identified on the bases of Locational Marginal ...
Optimal charging of electric vehicles considering constraints of the medium voltage distribution network
(2013-08-26)
The scope of this work is to optimize the charging of electric vehicles (EVs) in a controlled environment. The method uses a linear optimization technique, which determines the electrical power that will be delivered to ...
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 ...
Network reconfiguration and loss allocation in a deregulated environment of distribution systems
(2005-12-14)
Low flexibility and reliability in the operation of radial distribution networks make those systems be constructed with extra equipment as sectionalising switches in order to reconfigure the network, so the operation quality ...
Electrical Power Distribution System modeling with VHDL-AMS for the construction of a Real-Time Digital Simulator using FPGAS devices
(2012-12-01)
This paper presents a distribution feeder simulation using VHDL-AMS, considering the standard IEEE 13 node test feeder admitted as an example. In an electronic spreadsheet all calculations are performed in order to develop ...
Investigating effects of neutral wire and grounding in distribution systems with faults
(2004-12-01)
In some applications like fault analysis, fault location, power quality studies, safety analysis, loss analysis, etc., knowing the neutral wire and ground currents and voltages could be of particular interest. In order to ...
Distribution line models analysis for loss calculation within three-phase three-wire power flow algorithms
(2004-12-01)
Three-phase three-wire power flow algorithms, as any tool for power systems analysis, require reliable impedances and models in order to obtain accurate results. Kron's reduction procedure, which embeds neutral wire influence ...
