This paper summarizes the main results from (Wang 2013), which propose an extension of the traditional ac Optimal Power Flow (OPF) model to incorporate the Voltage Source Converter based Multi-terminal High Voltage Direct Current system (VSC-MTDC). The detailed VSC-MTDC system model is included in the extended OPF. A case study using the proposed M-OPF model and the Nordic 32-bus system evaluates the contribution of the embedded VSC-MTDC system on the overall system loss reduction. The study results show that the overall system loss of an ac transmission grid is not necessarily reduced by embedding a VSC- MTDC system into it. The reduction of the system loss by embedded VSC-MTDC system depends on their configurations and locations, and the VSC station loss ratio as well. (Wang 2013) F. Wang, T. Le, L.
