Computer-Aided Analysis of Power Flow in Power Systems

This project aims to perform power flow calculation and analysis on a 14-node power system. To achieve this objective, both MATLAB and PSASP software will be utilized for computation and analysis respectively. The specific requirements are as follows:

1. Implement power flow calculation for the power system using MATLAB. This requires programming to generate the nodal admittance matrix through systematic admittance summation, construct the Jacobian matrix containing partial derivatives of power equations, solve correction equations using Gaussian elimination algorithm for iterative solutions, and develop output routines to display the nodal admittance matrix, node voltages (including phase angles and magnitudes), as well as branch power flows (sending-end power, receiving-end power, and power losses). Finally, debug the program and execute it in the MATLAB environment to output results and organize them into tabular format.

2. Conduct power flow analysis of the system using PSASP software. Utilize the software's built-in functions to perform power flow calculations and output node voltages, branch power flows, and other relevant information for analysis. During the analysis process, careful adjustment of various parameters is necessary to obtain reasonable results.

3. Compare the calculation results between MATLAB and PSASP software, analyze their differences, and conduct comprehensive analysis and evaluation of the results.

Through these steps, one can gain in-depth understanding of power flow calculation procedures in power systems and master the methods of using different software for computation and analysis. Simultaneously, this provides valuable reference for solving similar problems in the future.
