Stability analysis of power system in cape verde with wind power under wind gust and short circuit fault

The short circuit fault can affect the stability of the power system mainly when a wind power is added. In some situation, the wind gust can happening simultaneity, which can became more complex and serious. Inclusively, the wind farm can be power off and disconnecting from the electrical grid. To study and preview this phenomenon before connect the wind farm into network grid, the use of simulation method has been a good tool. The power system of Santiago Island, Cape Verde, considering a wind farm with 9.35 MW of power installed, near of 40 MW-diesel plant and connected into the electrical networks is used as a case study in this paper. The simulation results by MATLAB/Simulink® showed a stable performance of power system and a protected wind farm under a situation of wind gust and short circuit fault.
