The paper is aimed at focusing the influence and more in general benefits and problems that medium size wind turbines, photovoltaic power plants, and small cogenerative generators embedded in a radial distribution network can produce regarding voltage profiles and power balance. In particular the novel capability of wind turbines to reduce active power in case of over-frequency is analyzed. This feature...
The paper is aimed at presenting the dynamic behaviour of a wind turbine equipped with a doubly fed induction generator (DFIG) in case of disturbances in the interconnected grid. A model of a DFIG is presented and adapted for analyzing the response of the wind generator to voltage control, frequency control, voltage sags and wind variations. Simulations, performed by a widely used power system analysis...
