Abstract: This paper presents the study of the impact of harmonic distortion generated by the thyristors controlled series capacitor (TCSC) in Algerian electric power system. By applying Fourier transform of terminal voltage and switching function, the TCSC model is used as a harmonic admittance matrix, in the frequency domain, and then integrated into a balanced harmonic load flow algorithm based on the Newton-Raphson method. The study has been carried out with the equivalent Algerian power system 114 bus. The total harmonics and RMS voltages are evaluated under different operating regions of the TCSC.
Keywords: harmonic power flow; nonlinear load; thyristors controlled series capacitor; TCSC; Algerian power system; total harmonic distortion.
