Modeling and damping controller design for static synchronous compensator

A STATCOM can be used for voltage regulation in a power system, having as an ultimate goal the increase in transmittable power, and improvements of steady-state transmission characteristics and of the overall stability of the system. In this paper a model of a SMIB with STATCOM which is suitable for both steady state analysis and dynamic stability analysis systems is developed. A damping controller is also designed for the STATCOM using root locus methods.
