Abstract

It is acknowledged that Distributed Generation, in spite of the benefits that it provides, causes harmonics problems due to the power converter interfaces. In this paper, a generic approach is adopted to reduce the harmonic injection from converter-connected DG units, using a phase-shifting technique. By changing the vector group between transformers that connect with either converter-connected DG or non-linear loads is operated off-line for a self-harmonic cancellation, without modifying the existing converter unit. The case study is based on the typical 17 bus, Dutch medium voltage (MV) network implemented in DIgSILENT PowerFactory.
