Harmonic Impedance Response Of Electrical Algerian Network

this paper investigates the impedance behavior of the large electrical power system with consideration of the capacitor bank and multiple nonlinear loads. Two methods have been used to predict the harmonic problems under these non sinusoidal conditions, which are the harmonic power flow and frequency scan. Both methods have been applied to the Algerian 114 buses equivalent network. The obtained results show the robustness of these tools to give some information about the resonance conditions at any bus and to visualize the frequency response of the Algerian network as function of the capacitor sizing and placement as well as nonlinear load position.
