Voltage Sourced Converter (VSC) HVDC Responses to Disturbances and Faults in AC Systems which have Low Synchronous Generation

The Technical Brochure analyzes the behaviour and control of Voltage Sourced Converter (VSC) HVDC systems connected to low synchronous generation AC systems, emphasizing the advantages and constraints of synchronous grid forming (SGFM) control over traditional grid following control, outlining desired SGFM features such as instantaneous active power response, voltage support, inertia, fault current contribution, and islanding capabilities, and providing a structured overview of HVDC system dynamics, control methods, practical limitations, and test circuits to assess controller performance under various conditions.
