Impact on Power System Dynamics of PI Control Limiters of VSC-based Devices

This paper presents and compares a variety of PI controllers with different implementations of windup and anti-windup limiters. The paper shows that a precise modeling of these controllers is of crucial importance for an accurate prediction of the dynamic response of power systems that operate close to their operational limits. The focus is on PI controllers included in voltage sourced converters. In particular, the case study considers two relevant applications of such devices, namely the Static Synchronous Compensator and a Multi-terminal Direct Current grid.
