Impact of voltage source converter (VSC) based HVDC interconnection on AC power system energy transmission wide-area disturbances

摘要

The future of Power systems include high penetration of renewable energy and interconnectivity between different networks through VSC-HVDC. However, this has increased the stress on transmission systems. WAMS and WAP aim at providing an awareness of the system state and increase the robustness when faced with disturbances, thus increasing security of operation. In this context, the present work provides an overview of the key concepts and challenges of wide-area in Power System energy transmission, as well as highlighting possible impact of VSC-HVDC towards disturbances. In order to be able to assess these disturbances, this paper proposes a methodology to study of VSC-HVDC contribution towards wide-area disturbances and impact on protection systems.
