Multiloop PI Controller Optimization and Low-Frequency Oscillation Analysis in VSC-HVDC Systems
Voltage-source-converter-based high-voltage direct-current (VSC-HVDC) transmission is increasingly used for renewable-energy integration, asynchronous-grid interconnection, and dynamic support of weak AC networks. However, fast converter control dynamics, reduced system inertia, and interaction between the inner and ou...
