Abstract

Renewable energy resources are being integrated into power systems around the world and replacing conventional generators to reduce carbon emission. Voltage source converter based multiterminal HVDC (VSC-MTDC) is identified to be a promising technology to facilitate the integration and utilization of large amounts of renewable energy resources across large geographic areas. Many challenges exist in operating such a combined AC-MTDC power system under a high renewable future. This dissertation addresses three challenging problems in terms of improving dynamic performance of an AC-MTDC system, which are AC system frequency control, DC voltage control, and implementation of VSC-MTDC controls on practical large scale systems.
