Abstract
This paper mainly deals with OPF with fault level constraints (FLC) by using an iterative process. The OPF is to provide solutions in conditions where fault current levels at buses are within the
specifications of switchgear. The aim of this paper is to consider the impacts of varying load voltage magnitudes to the bus impedance. This is done by formulating the bus impedance as a function of varying load voltages. FLC-OPF calculation was implemented by MATPOWER with corresponding modifications on its library source codes to cater non-linear constraints. The results showed that as FLC-OPF was imposed, the formulation considering the impact of varying voltage magnitude on the bus impedance have a better performance compared when the bus impedance is not considered to be a function of load voltage magnitude.
