This paper analyzes the effect of limited range battery electric bus on operation services charged at garage. A model has been built to calculate performance routes according type charging scheme. It evaluates total cost service, considering necessary resources due limitations and constraints. Based analysis real data a line in city Barcelona, diesel or hybrid vehicles are still found be more c...

Abstract: This study presents an inductive power transfer (IPT) system for electric vehicles (EVs) based on EE-shaped ferrite cores. The issues of the IPT system such as efficiency, air gap, displacement, dislocation, and motion are discussed. Furthermore, finite element analysis software is utilized to simulate the IPT system operated under large air gap conditions. Simulation and measurement ...

In this paper, a modified discrete particle swarm optimization is presented to find the optimal placement and size of capacitors in a distribution system. The objective function is composed of the line loss and the capacitors investment cost. The bus voltage and the feeder current as constraints are included in the objective function by a constraint penalty factor. To validate the proposed meth...

A comprehensive model for stochastic load flow analysis in electric power systems is proposed for the purpose of estimating the statistics of bus voltage magnitudes, circuit currents and transmission line power flows. The proposed method is driven by a realistic nonconforming stochastic electric load model, defined in terms of few independent stochastic processes; it is based on the quadratized...
