Worldwide the energy sector is mov-ing towards a greener and more sus-tainable future by integrating morerenewable based generation plantswhile decommissioning conventionalgeneration units. As a result thepower grid is seeing a decreasein system inertia and is becomingmore susceptible to power oscilla-tions. Power systems stabilizers wereused in conventional power plantscontrol schemes to mitigate these os-cillations. Therefore, in order tomaintain the stability and security ofpower supply the renewable genera-tion plants should be able to providesimilar capabilities. This project isinvestigating and proposing a feasi-ble mitigation methods for the powersystem oscillations implemented inwind turbines and/or at wind powerplants. These methods should beeasily applied worldwide on vari-ous grid connection characteristicsby wind turbine manufactures andplant owners. The proposed methodsshould also provide effective dampingto power grid while not endangeringthe operation of the wind turbines
