Optimal Control of VSC for STATCOM Applications [PDF]

IFAC Proceedings Volumes, 2012
Abstract In this work, a voltage source converter (VSC) is configured to perform STATCOM tasks and generate reactive power. An optimal H ∞ controller has been successfully implemented including an anti-windup compensator. Data from an experimental test bench is provided and compared with simulation results showing good accuracy level.
