Load flow analysis is essential for understanding and optimizing power system operations. It helps in determining the steady-state behavior of power systems, ensuring efficient and reliable energy transmission. This study aims to analyze a 5-bus power system using the Gauss-Seidel method for load flow analysis. The objective is to calculate steady-state voltages, voltage angles, real and reactive power flows, line losses, and overall reactive and active power losses. The Gauss-Seidel method is employed due to its suitability for small systems and ease of understanding. The method iteratively calculates the voltage magnitude and phase angle at each bus until convergence is achieved. The analysis reveals the steady-state conditions of the 5-bus power system. The calculated results include voltage magnitudes, voltage angles, real and reactive power flows, line losses, and overall reactive and active power losses. The analysis also provides insights into the system’s operating conditions and helps identify potential areas for improvement. The Gauss-Seidel method proves to be effective in analyzing small power systems, providing accurate results with minimal computational complexity. The study demonstrates the importance of load flow analysis in understanding power system behavior and optimizing system operations. The results highlight the significance of considering reactive power in power system analysis to ensure efficient energy transmission.
