Unsymmetrical operation of a DIPFC to reduce network interactions

In this paper an unsymmetrical operating dynamic interphase power flow controller (DIPFC) is described with a fundamental-component based model. The unsymmetrical control of this thyristor controlled FACTS device can be used to decouple the symmetrical components (positive-, negative- and zero-sequence component) of two connected arbitrary network notes. In an example network it is shown how the power flow between two networks can be regulated with the DIPFC and how the negative- and the zero-sequence voltages are reducible if one busbar is supplied with an unsymmetrical voltage.
