The work of CIGRE Study Committee B4 covers all aspects of HVDC and Power Electronics. The work includes monitoring the performance of existing transmission systems, planning, design, testing and operational issues of the new projects. The scope of B4 addresses all the relevant target groups in the power industry interested in power electronics. Economic and environmental subjects of this techn...

Large offshore wind farms are recently emerging as promising alternative power Sources. Long distances between offshore generation and onshore distribution grid demand new solutions for their connect alternative to conventional AC transmission above a certain cable length. This paper presents a new VSC transmission topology for HVDC grid connection of offshore wind farms.

Modular multilevel converters (MMC) play a dominant role in integrating remotely located renewable energy resources (RER) over the high-voltage direct current (HVDC) transmission network. The fault ride-through capabilities of MMC-HVDC network during low-voltage faults and power fluctuation due to RER intermittency are major obstacles effective integration energy. In response, this article prop...

Abstract Offshore wind farms (OWFs) have received widespread attention for their abundant unexploited energy potential and convenient locations conditions. They are rapidly developing towards having large capacity being located further away from shore. It is thus necessary to explore effective power transmission technologies connect OWFs onshore grids. At present, three types of been proposed O...

Most of the wind power plants currently installed at North Sea are near to shore connected with the onshore grid through AC cable. AC transmission technology is proven and reliable, but there will be a need to switch from AC to DC transmission since large number of offshore power plants at longer distance to shore are expected to be installed by the end of 2020. Furthermore, to enhance the inte...

This work presents the prototype of a standard for HVDC, designed to be used in the range of 1kV to 50 kV and calibrated in low voltages. In HV, it will be the link in the chain of traceability between the INMETRO standard and the dividers used by industrial laboratories.

Modular multilevel converter (MMC) has been widely used in VSC-HVDC system for its smooth output waveform, low harmonic content and switching loss. But compared with the conventional LCC-HVDC system, modular a short development history, few engineering applications, high failure rate lacks of very effective protection strategies, which limits further development. Therefore, this paper firstly i...
