Abstract
Renewable energy systems are tending to become more and more present in the energy market and wind power has already proven its potential. Wind parks of thousands of MW are planned to be place into sea faraway from the mainland. Appropriate transmission systems should be designed in order to be able to handle a significant amount of power with high efficiency and to be economically competitive. This project deals with the investigation of a Multiterminal DC connection, based on VSC technology, between one offshore wind farm and two different grids. The goal of this project was to provide an innovative control algorithm for the power interchange of the three systems. The modeling and designing of the WF components, of the power converters, of the DC system components and of all the controllers played a major role in develop a simulation platform for future studies. Verifications follow the theoretical investigations in order to prove the reliability of the modeled system for different test scenarios. The entire system is build and simulated in Power Factory DIgSILENT simulation tool.
