An innovation breakthrough enabling reliable HVDC grids· PDF file12/10/2012· 2. SYSTEM DESIGN REQUIREMENTS An HVDC grid is formed when more than two converter stations are interconnected on the HVDC side via HVDC cables or overhead lines. Each converter station or each terminal of the HVDC grid couples the HVDC grid to an AC grid. In order to maintain the converter`s active and reactive power

HVDC grid test models for different application scenarios ...· High Voltage Direct Current (HVDC) grids are the most effective solutions for collection, integration and transmission of large scale remote renewable resources to load centers. A HVDC grid test model can provide a common reference and study platform for researchers to compare the performance and characteristics of a DC grid with different DC control functions and protection strategies.
