Investigation of Static Voltage Stability and Power Losses of ZIP Load Modeling in Power Systems

Abstract

One of the most important problems with energy consumer is effect of static load modeling in power systems. In this study, Effects on static voltage stability and active-reactive power losses of static load modeling in 5 bus power system were investigated. As static load modeling; constant impedances, constant current, and constant active power (ZIP) load model has been used. The impacts of ZIP load modelling on different parameter values were evaluated in terms of voltage-maximum loading parameters and active-reactive power losses. It was found that static voltage stability and active-reactive power losses increased while maximum loading parameter values decreased as the ZIP load modelling constant current value changed.
