What this means is that wind turbines should be continuously on-line and supply the grid during voltage sags. Large voltage sags induce high voltages in the rotor circuit of the DFIG and thus the rotor current rises and could exceed the current capability of the converter switches. In the instant of such faults, there is usually a power imbalance between the generator and the grid that usually cause the DC-link voltage rise because of the excess power generated that can not be transferred to the grid. Against the use of crowbar to block the converter and then to disconnect the generator from the grid or by reducing the power generated or maximizing the power supplied to the grid, an active damping criterion in the control of the BtB converter is proposed in this book. The phenomenal increase in these quantities together with other disturbances are by this process rejected and/ or damped thereby making the grid less sensitive to harmonics and oscillations. By this, the wind turbine stays on-line and continues to supply the grid.

Continued exploitation and utilization of conventional energy resources (CER) result in greenhouse gasses. The world-wide trend towards deregulation of the electricity markets created a boost towards the use of renewable energy resources (RER) in the power system. Based on the stochastic behavior of RER, together with the fluctuations of the consumer energy demand on daily and seasonal bases, they are therefore not good candidates for ancillary services required of electricity generators when operated singly without backups. In order that power production may be increased or decreased quickly in response to load demand fluctuation, power from these sources are best operated in hybrids with backups. The hybrid combinations of these resources with or without backups to generate environmental and ecological friendly power and mitigate the emissions of greenhouse gasses may be seen as heavenly marriage of the greens .
