Reactive power handling capability is requested to distributed power generation systems by the new national grid codes. The reactive power exchange should be maintained inside a triangular/rectangular reactive power capability curve. Among distributed power generation systems based on renewable sources, small wind turbines systems are becoming an increasingly attractive structure for the proposal...
This paper is focused on the control of small wind turbines, rated less than 200 kW, in grid-interactive microgrids. The considered system is based on a back-to-back power conversion stage. The management of the active and reactive power exchange in the different operating conditions is the key point to allow a practical integration of wind turbine systems in the main electrical grid. This issue lies...
This paper deals with a small wind turbine system (WTS) constituted by a permanent magnet synchronous generator (PMSG) connected to the grid via a back-to-back converter. The Low Voltage Ride through (LVRT) requirements for the WTS are described and the nonlinear dynamics of a grid-side converter is analyzed in the presence of voltage sags. The study shows that new chaotic phenomena are generated...
