HVDC Control and operation for the integration of extremely high-RES systems with focus on permanent DC faults

This master thesis presents the control and analysis of a DC fault on a zero inertia offshore grid integrating multiple Voltage Source Converters. The system analyzed consists in an offshore grid which includes two wind power plants and two offshore converter platforms. These two offshore converter...
