Analysis of load flow based on power system analysis software package by using the IEEE 30-bus system

Abstract A power-flow study is a numerical analysis to judge the stability of the power system during operation. By analyzing the results of the load flow calculations, the transmission line, the load distribution, the power factor, the equipment capacity, the distribution network, and the power quality and reliability of the distribution network are improved. This paper uses the IEEE 30-Bus system as an example of building a modified system via the power system analysis software package (PSASP) for the power-flow study. Other simulation tools are validated by using the MATPOWER toolbox and MATLAB/Simulink. The result of the load flow calculation for the three simulation tools is almost consistent, so the practicability of the tool is proved. It is verified that the PSASP is one of the reference simulation tools for power system analysis.
