Abstract


Unified power flow controller (UPFC), as the name suggests is used to control the power flow in transmission systems. UPFC is a kind of flexible alternating transmission system (FACTS device) which is able to control both active and reactive power along with voltage magnitude as well as phase angle. This paper proposes the use of phasor model of UPFC to control the real and reactive power flow in integrated power system (consist electric grid and wind power generator). The DFIG technology felicitates us to get maximum energy from the wind for wind speeds of low value by optimizing the turbine speed, while minimizing mechanical stresses on the turbine. The modeling is done in Matlab/Simulink using IEEE 5-bus and 10-bus system incorporating UPFC. The models are simulated to find the value of real and reactive power flow and waveforms for each of the model. The simulation results show clearly that the model using UPFC have enhanced value of real power compared to the model without UPFC. The numerical result of real power made very clear that the UPFC can be used in integrated power system for the maximum use of the transmission lines.
