The paper main objective is to provide a feasibility study for the connection of a wind turbine to a dcmicrogrid. The wind turbine, provided by WES, uses a squirrel-cage generator, which is a given projectvariable. Hence, the main aspects which determines the performance of the the wind turbine connectionto the dc microgrid are related with the turbine control – such as the maximum power point tracking(MPPT) system and pitch control – and other relevant mechanical and electrical components, such asthe generator and the ac-dc converter. Additionally, a dynamic analysis is performed to select a powerconversion unit – dc-dc converter – which is able to provide energy with high quality standards from thewind turbine to the dc microgrid. Based on the selected power convertion unit, a control strategy for thecomplete wind energy conversion system – from wind turbine to the dc microgrid – is developed. For theselected wind energy conversion system configuration, measurements performed on a real wind turbineare used in a hybrid simulation to validate the developed dc microgrid control and dynamic models. |
