One of the main limitations of the classic control of the Syncronverter (SV) is that there are not enough degrees of freedom to allow the designer to set the desired dynamics of the injected active and reactive powers (p and q, respectively). Moreover, the classic control also results in great coupling between p and q. To solve these issues, a controller based on the feedback linearization technique is presented. The proposed strategy allows the designerto set the dynamics of p and q, and also reduces the coupling between them to negligible levels. This controller also reproduces the behavior of the classic controller in steady state, modifying both p and q to changes in the grid frequency and point of common coupling voltage, respectively.
