In this paper, a power supply system for hybrid renewable energy conversion is proposed, which can process PV (photovoltaic) power and wind-turbine energy simultaneously for step-down voltage and high current applications. It is a dual-input converter and mainly contains a PV energy source, a wind turbine energy source, a zero-voltage-switching (ZVS) forward converter, and a current-doubler rec...

In this paper, the design and implementation of a permanent magnet synchronous generator (PMSG) based wind energy conversion system battery bank storages are connected to utility grid. It has phase locked loop (PLL) control strategy as it provides for single-phase grid inverter with constant dc-link voltage. The is interfaced through diode bridge rectifier (DBR) dc-dc boost converter, single vo...

High penetration of wind power into the grid necessitates coordinated action energy conversion systems and grid. A suitable generation control is required to fulfill integration requirements, especially during faults. system using a pair voltage source converters with squirrel cage induction generator coupled turbine proposed provide fault ride-through threefold used for providing effective via...

A boundary layer wind tunnel facility has been adopted in order to conduct experimental measurements of the flow field around a model of the Panorama Giustinelli Building, Trieste (Italy). Information on the main flow structures has been obtained by means of flow visualization techniques and has been compared to the numerical predictions of the vortical structures spread on top of the roof, in ...

A new application of the three-phase buck-resonant converter is presented in this paper. It is shown that the analyzed converter is suitable to operate as the rectifier stage in low power wind energy conversion systems (WECS) based on permanent magnet synchronous generators (PMSG) with variable wind speed. As main features, it presents a single controlled switch, simple implementation and contr...
