The world population depends highly on fossil fuels (for power generation, transportation, etc), this leads to oil price increases because of the depletion of fossil fuels. This paper is dealing with the use of RES in transportation. Pollution from the today transportation means, based on ICE (burning gas) especially in urban conglomerates and is off great concern. The renewable energy sources (RES)...
This paper is deals with the implementation of a software control method for harmonic content evaluation in the dq synchronous rotating reference frame for grid side VSIs (Voltage Source Inverters) used in DPGS (distributed power generation systems) applications. In order to verify the performance of the proposed approach, in experiments a DC voltage source (playing the role of a generic renewable...
This paper deals with the design and implementation of PR current control method in the αβ stationary reference frame for the grid side converter in Distributed Power Generation Systems (DPGS) applications. The goals of this paper are to implement a control technique for the grid side inverter including a LC filter, a compensation technique for low-order harmonics and to examine the grid current harmonic...
This paper presents a renewable hybrid system with battery storage which can work as a stand-alone and/or grid-connected mode. It consists in a wind turbine with permanent magnet synchronous generator (PMSG) and a photovoltaic panel forming a single-phase micro-grid. The wind generator and photovoltaic module are connected to the micro-grid via single-phase converters. Maximum power point tracker...
This paper presents a wind turbine system operating in grid-connected mode. Grid connection of small permanent magnet synchronous generator (PMSG) based wind turbines requires a power conditioning system comprising a bridge rectifier, a dc-dc converter and a grid-tied inverter. The control structure, based on a current controller and a synchronization algorithm are implemented in the grid-tied inverter...
This paper analyzes the operation of small wind turbine system with variable speed Permanent Magnet Synchronous Generator (PMSG) and a Lead Acid Battery (LAB) for residential applications, during wind speed variation. The main purpose is to supply 230 V/50 Hz domestic appliances through a single-phase inverter. The required power for the connected loads can be effectively delivered and supplied by...
Energy storage devices and solutions are required for power quality and balance within wind systems. In the context of rapidly expanding of distributed energy sources, the wind energy converters are in the center of interest. In this case, the direct dependence of the power generation capability for a given wind speed represents a major problem of wind energy conversion with regard to large-scale...
This paper proposes into determining an appropriate electrical vanadium redox flow battery (VRB) model and its integration with a typical stand-alone wind energy system during wind speed variation as well as transient performance under variable load. The investigated system consists of a 3 kW variable speed wind turbine with permanent magnet synchronous generator (PMSG), diode rectifier bridge, buck-boost...
