A paradigm shift in power systems is observed due to the massive integration of renewable
energy sources (RESs) as distributed generators. Mainly, solar photovoltaic (PV) panels and …

This thesis deals with the analysis, modeling, and control of the doubly-fed induction
generator (DFIG) for wind turbines. Different rotor current control methods are investigated …

Direct grid coupling of permanent magnet synchronous generators (PMSG) for wind energy
conversion systems provides certain advantages with the penalties of maximum power point …

This report is a summary of the existing literature available on the subject of
electromechanical conversion in wind turbines. The status of wind turbines as marketed …

The efficiency of the electrical system of doublyfed induction generators, for variable speed
wind turbines, in comparison to other electrical systems has been investigated. It has been …

The aim of this article is to evaluate the performance of micro wind turbines in a built-up
environment. For this purpose, five independent micro wind turbine systems, consisting of …

The paper examines different control strategies for a VAWT drive. A technique is also
proposed for a sensorless application allowing to maximize the output power up to the rated …

Direct Grid Connection of Permanent Magnet Synchronous Generators (PMSG) has well-
known disadvantages such as unstable operation and poor energy extraction when the …

A directly driven permanent-magnet wind generator was designed. The rated power of the
generator was 500 kW at a synchronous rotational speed of 40 RPM. The electrical …

This research investigates a low-cost generator and power electronics unit for smallscale (<
10kW) wind turbines, for both standalone and grid-connected applications. The proposed …
