Abstract
The objective of this Masters Thesis is to investigate the system stability implications of integration of power electronic converter interfaced generation (CIG) into conventional power systems. Due to differences between conventional generation and (CIG), the power system fault currents, voltage response, and frequency response will likely change with increased penetration of (CIG). This research has employed state of the art software tools to perform simulations on the IEEE 24-Bus Reliability Test System (RTS-24), appropriately modified to include converter interfaced generation. Time-domain dynamic simulations and fault calculations have been performed for the system. A comprehensive set of simulations has been performed on the base case, comprised entirely of conventional generation. Conventional generation was replaced by (CIG) in the model, one generating station at a time until (CIG) penetration reached one-hundred percent. The comprehensive set of simulations has been performed at each level of (CIG) penetration. The results have been compared to the base case, with a focus on voltage response, frequency response, and fault current levels of the power system.
