Power flow in typical series-parallel hybrid filters topologies

Abstract

In this paper, analyzed hybrid UPQC systems consist of the series and parallel APF with added resonance filter LC. The authors focus on analysis of the power flow between active filters at different configurations. This problem is significant, because it makes possible to find optimum configuration of the hybrid UPFC and power of the additional sources elements. Presented systems differ from each other with respect to flow and values of the additional power sources.
