dc.description.abstractThe aim of this Specialization Project is to implement and demonstrate a general AC/DC power flow solution in the Matlab environment. This task is interesting from the point of view of the increasing development of the integration of offshore wind power, especially in the North Sea area. The solution proposed in this paper, is valid for systems consisting on one DC grid, each of its buses is connected to different AC grids. Specifically, this study focuses on a general DC grid of three nodes and three consequent AC grids. In this project, a complete procedure on how to set-up the power flow model is developed and described. The first step taken in this process consists on the calculation of the power flows of all the AC grids, in a sequential way. In addition to the calculation of all the involved AC systems, the DC power flow has to be solved as well. The calculations of both power flows, AC and DC, have been implemented using the Newton-Raphson solution algorithm. A key challenge in this procedure has been to model the connection between the AC and DC grid through the HVDC converters. Several possibilities have been studied, mainly depending on the type of bus in question. A study and comparison between a converter with or without losses have been done as well. The final achievements of this Specialization Project consist on a Matlab code solving successfully this matter, highlighting that it is programmed in a general format, so that it enables modifications on the previous explained configuration between the DC and AC connection by simple changes. This enables the future connection of more AC grids if needed. Additionally, it seems obvious that the election of the slack node is a critical parameter that will influence the results; but in this work, an investigation and discussion is made about the possibility of controlling other parameters of the grid, as for example the AC and DC power at the nodes.es
