With the degradation of the environment and the decline of fossil sources announced in recent years, the use of renewable energy is experiencing strong growth. Photovoltaic electricity is the promising technologies for the applications in isolated sites not served by the power grid. However, the productivity of a PV array depends mainly on weather conditions (irradiation and temperature). In this...
In this paper, we will study the influence of the blades and shaft's rigidity on the stability of wind generator when a voltage dip appears. First, we present the model of the wind turbine, taking into consideration all damping coefficients. In this case the turbine will be represented by a three masses model. Then, neglecting the turbine blades' damping model becomes two masses. Finally, considering...
