Analysis of Distribution System Voltage Security Using the Gauss- Seidel Method
Voltage security is an attractive asset to power distribution system processes and ensures reliability and stability of voltage distribution amid various loading conditions. In this work, Gauss-Seidel iterative methodology is employed to perform analysis on voltage security of distribution networks. The technique allows the in depth assessment of the voltage bus profiles by solving power flows. Identification of the weak nodes and potential violations of the voltage achieves with the assessment of the voltage stability margin of the system, simulating the different loading conditions. Gauss-Seidel method is efficient and simple to go about distribution network analysis due to the simplicity of this method in radial systems. The results outlined the usefulness of the method in the planning and operational decision making in achieving enhanced voltage security in distribution systems by indicating how the voltage drops and voltage stability issues vary with the variations in the loads.
