This work presents an adapted model for the synchronverter to become suitable for operation without an electric energy source connected to the dc-link, like for example, a STATCOM or an active filter. In addition, a theoretical dynamic model for the project of the controller is presented, if the converter is applied to power systems, based on an investigation on the origins of the system-frequency oscillations. To verify the theories, part of the Brazilian National Grid (SIN) was modeled in the PSCAD simulator and the adapted synchronverter model was inserted to operate as a STATCOM. The results agree with those predicted analytically.
