In the most real-world power systems, the share of wind power penetration in total installed generationcapacity is rapidly increasing. This large-scale integration of wind power into an electric power systemposes challenges to the power system operators and planners. One of the main challenges is tomaintain sufficient margins for transient stability. High penetration of wind power causes reduction ofthe total kinetic energy stored in through rotating masses since wind generators are decoupled from thegrid by power electronic converters, and therefore, cannot contribute to the inertia of the grid. Theresulting reduction of grid inertia may cause higher risk of transient instability. In this paper, trajectorysensitivity analysis (TSA) technique is used to determine the impacts of decreasing inertia of differentgenerating units on the transient stability of power system. Numerical results from IEEE 10-machine39-bus test system demonstrate the usefulness of the proposed approach.
