Abstract:

The power quality problem occurred due to a non-linear load in the distribution network and its severe impact on sensitive loads. To overcome this problem, the new series, parallel FACTS device use. The Interline Power Flow Controller (IPFC) is a VSC based Flexible AC Transmission System FACTS controller for series compensation with the unique capability of power flow management among the multiple transmission lines in the transmission system. The performance of the considered IEEE 14 bus system is analyzed in terms of oscillations using IPFC. In this work, An IEEE 14 bus system is modelled in MATLAB/SIMULINK software. The most essential controller in FACTS controllers is the Unified Power Flow Controller(UPFC).UPFC is the most versatile FACTS device for real and reactive power flow control and voltage regulation. By incorporating UPFC in our modern power system it is possible to control the power flow thereby decreasing the energy crisis to a greater extent. UPFC can provide simultaneous control of real power and reactive power flow by modeling the power system in MATLABSIMULINK, thereby improving the performance, power quality, and voltage profile in the power system Initially, the basic transmission line system model is simulated. After that connect IPFC as well as UPFC controller one by one is simulated in MATLAB and check the performance of output waveform. This analysis is carried out using MATLAB/Simulink
