High-Voltage Direct Current (HVDC) is a key enabler for a carbon-neutral energy system. It is highly efficient for transmitting large amounts of electricity over long distances, integration of renewables and interconnecting grids, opening up for new sustainable transmission solutions.
ns, risk based reliability management,... Planning: HVDC systems need to be integrated in the future power system in such a wa that they can form multi-terminal HVDC grids. This includes integrated and onshore grids, (inter-) connection of different control zones and synchronous areas, power wheeling ove
Hitachi Energy has long experience in providing maintenance service and delivering upgrades for HVDC links all around the world. The control system is the brain in HVDC transmission systems. One of the most important advantages with modern HVDC technology is the controllability.
A PV HVDC grid connected system realizes PV power collection and voltage step-up through DC/DC converter of PV generation unit, making the output voltage directly reach the appropriate transmission voltage level. The typical structure of a HVDC collection and grid-connection PV power plant system is shown in Figure 2.
nology has been done in the past decade or so. HVDC converters based on VSC technology have been used for connecting offshore wind power plants or for nterconnecting countries and/or power systems. Many of the developments have been facilitated by multiple initia
Compared with the traditional AC collection and grid-connection scheme, it can reduce the power conversion links and improve the system efficiency. As one of the most important devices in the application of a PV HVDC collection and grid-connection system, a high voltage, large capacity, high step-up ratio DC/DC converter is the critical technology.
