Abstract
This paper aims to adapt the structure and design procedures of a power system stabilizer (PSS) to the context of the use of DC-DC converters to mitigate the oscillations due to connection of constant power loads (CPL). In this sense, a buck converter with voltage previously regulated by a controller is considered and based on the power variations gain and phase contributions cause in the system, the active auxiliary loop design is carried out to mitigate these effects. Furthermore, by modifying the structure of this loop, the performance and stability of the system are evaluated.
