The main task of the paper is to gain a common understanding of basic operating and design principles of HVDC Grid Systems, and to make the ground for more detailed setting work. The HVDC systems are moving from the phase of point-to-point (PTP) connections to the stage of the transmission systems interrelating more than two stations and applying multi-terminal (MT), multi-vendor (MTMC) HVDC Voltage-Sourced-Converter (VSC) systems. The growth will be modular, e.g. in steps, starting with interrelating PTP connectors and founding three-pod, radial systems . Then, such modest systems may gradually be interrelated into circular and engaged HVDC-VSC systems including more HVDC lines and DC converter stations. This paper describes the thoughtful, requirement and setting of design and action principles of the HVDC grids seen as the first wanted steps towards such MTMV systems.
