in this paper, we present a new method to determine the optimal location and parameter settings of unifiedpower flow controller (upfc) for removing voltage violations and transmission lines overloading. upfc isconsidered as the most powerful member of the facts devices, that it can control shunt and series power flow.this option gives to upfc the power to control the voltage profile and transmi...

Solid-state switch-mode rectification converters have reached a matured level for improving power quality in terms of power-factor correction (PFC), reduced total harmonic distortion at input ac mains and precisely regulated dc output in buck, boost, buck–boost and multilevel modes with unidirectional and bidirectional power flow. In this paper, an improved power quality converter employing con...

Due to their flexibility, Electric Vehicles (EVs) constitute an important asset for the integration of renewable energy sources in Smart Grid. In particular, they should have a dual role: as controllable load and mobile generator with low inertia. To perform these tasks, chargers must provide electronics power flow from grid vehicle vice versa. This bidirectionality can also be implemented wire...

In this project presents a new non conventional energy source based bidirectional dc/dc converter for transfer the power in both directions. The nonconventional source of solar energy with Maximum Power Point Tracking is used to avoid the demand of electric power, which is inexhaustible and non pollution .The maximum power point traction is the combination of switch mode converter and Controlle...

In this paper, the concept and implementation of field-orientation control (FOC) of a doubly excited brushless reluctance machine (DEBRM) for variable-speed drives and generating systems are presented. A stator-flux-orientation scheme is employed to achieve decoupled control of torque and reactive power. A 2-hp DEBRM prototype system with a digital signal processor (DSP)-based controller and a ...

The recent and massive investments in Electric Vehicles (EVs) reveal a change of paradigm in the transports sector and the proliferation of EVs will contribute to an effective reduction in the emissions of greenhouse gases. Nevertheless, for the electrical power grids EVs will be extra loads, which will require the demand energy to charge their batteries. With the advent of the Smart Grids, bes...
