“…Among several wind generation technologies, variable-speed wind turbines using doubly fed induction generators (DFIGs) are very common in the industry due to various advantages, such as improved efficiency and controllability. Since the control of active and reactive powers can be decoupled with DFIGs, power oscillation damping controllers (PODCs) can be incorporated into the corresponding converter control loops in order to provide damping of power system oscillations [3][4][5][6][7][8][9][10][11].…”

“…In general, a great number of strategies and techniques to design PODCs can be found in the literature [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. However, due to the non-linear nature of power system dynamics, any design based exclusively on a linear analysis approach is often questionable [19].…”

“…[4], the use of lead/lag compensation blocks is unnecessary for wind turbine applications. However, some other investigators, such as [3, 5–7, 9, 10], have proposed PODC's structure such as the one widely used for conventional power system stabilisers, where phase compensation is a basic component. Whether or not lead/lag blocks are used at all, one of the main issues in the application of PODCs for DFIG‐WFs is to consider whether any of these controllers has an effect on the DFIG shaft torsional mode.…”

Contribution to the damping of inter-area and torsional oscillation modes, in doubly fed induction generators (DFIG) based wind farms, by power oscillation damping controllers (PODCs) based on two conventional structures and a fuzzy control strategy is investigated in this study. In this regard, a PODC with no lead/lag compensation is designed first and then a PODC with one lead/lag block is developed using eigenvalue techniques and the application of an iterative process based on the bat optimisation algorithm (BOA). Moreover, a fuzzy PODC, based on a simple fuzzy controller and tuned with the BOA according to the system transient response under a critical perturbation, is also designed. Comparative performance of the three PODCs is evaluated on a multi-machine power system. It is observed that all three PODCs can contribute to improving the damping of inter-area oscillations. However, eigenvalue analysis and non-linear time domain simulations reveal that each of them may also impact to a lesser or greater extent the shaft torsional oscillation mode damping. Their relative impact in this regard is also investigated.
