Abstract: This paper reveals investigated result of an integrated wind farm fed to a power grid through a generalized unified power flow controller (G-UPFC), to synchronously achieve voltage-fluctuation mitigation as well as stability improvement. The performance of the considered wind farm is simulated by an equivalent 9 MW doubly-fed induction generator (DFIG). An IEEE 14 bus system is also connected with the system for load flow analysis. A fault is deliberately created at a bus. This integrated power system has been simulated with and without G-UPFC and simulation result of voltage waveform at different buses is captured with respect to time. The results illustrate that the G-UPFC is very effective in voltage fluctuation mitigation and transient stability improvement.
