| Abstract: | High penetration of power electronic converter technologies is reshaping power infrastructure, bringing new challenges in managing and stabilizing power grids, emphasizing the need for advanced simulation techniques. Traditional RMS simulation tools are limited in accurately representing the fast-switching actions and complex control mechanisms of modern power systems. Conversely, EMT simulations offer more detail, while are resource-intensive and impractical for large-scale analysis. The dissertation proposes a dynamic phasor simulation method for a typical two terminal Voltage Source Converter based High Voltage Direct Current (VSC-HVDC) transmission system. This approach aims to provide precise modeling of power electronic devices and efficient simulation of broader power system dynamics, essential for analyzing grids with high power electronic penetration. The dissertation's structure includes a literature review of VSC-HVDC transmission systems and hybrid power system simulation techniques, highlighting the advantages of the dynamic phasor system model in terms of accuracy and computational efficiency. It also discusses the theoretical framework for developing a detailed dynamic phasor model for hybrid EMT/RMS simulations applied to VSC-HVDC systems, and the methodology for developing the hybrid simulation model. Subsequent chapters present the results, discussions, and conclusions drawn from the study. |
