Responding to more demand in coming years, the task of the small wind energy industry requires progress on several fronts-from public policy initiatives, to technology development, to market growth. Enhanced technologies such as contra-rotating blades, transmission systems, lubrication, airfoils, generators, and power electronics will lower cost and increase energy production. This paper mainly considers...
With the increasing penetration of wind power into electric power grids, energy storage devices will be required to dynamically match the intermittency of wind energy. This paper proposes a novel two-layer constant power control scheme for a wind farm equipped with doubly fed induction generator (DFIG) wind turbines. Each DFIG wind turbine is equipped with a supercapacitor energy storage system (ESS)...
In this paper, a comprehensive time domain model for a wind park, suitable for stability analysis, is presented. The wind generator is modeled with a reduced order model for an asynchronous machine, whilst the wind turbine model takes into account the dimension of the turbine, the rotor blade and blade pitch angle. Each wind generator incorporates a STATCOM (static compensator) controller in order...
This paper proposes a new DFIG system using matrix converter with simple modulation scheme, which can effectively interconnect the wind power system with the power grid. Matrix converter is very difficult for the DFIG application because of sensitive commutation process. In this paper a simple and easy modulation scheme for matrix converter called direct duty ratio pulse width modulation was developed...
