Abstract

Shunt-series ac links constitute a class of so-called vector switching converters, capable of controlling power flows by synthesising an adjustable series voltage. A novel steady-state model for the recently introduced three-leg shunt-series ac link, suitable for power flow studies, is developed in this study. The new model is then applied in two optimal power flow problems arising in distribution systems, namely, power loss reduction and integration of distributed generation, where the performance of the three-leg topology is compared with that of the conventional four-leg scheme. The CIGRE Task Force C06.04.02 benchmark network is used as case study.
