Voltage Fluctuations and Sensitivity Assessment of Load Flow Solutions for the IEEE 9-bus System

This paper presents a load flow analysis for voltage sensitive loads on a nine-bus test network with voltage sensitive components. As a result, the present study conducts load flow observation for voltage-sensitive loads on an IEEE 9-Bus test network. Furthermore, the impact of voltage sensitive load on load flow is analysed and assessment of the variations of initial voltages of load bus is carried out. A series of iterative load flow model is additionally developed, allowing the numerous load concepts to be conveniently integrated into such system parameters. The simulations are carried out in MATLAB for test case of IEEE 9 Bus system. The methodology presented in this study can also be applied to networks with a mix of the three types of load on each line.
