Application of VSC HVDC in a System Black Start Restoration

A robust and strategically devised black start restoration (BSR) procedure is critical to ensure that the power system is restored as efficiently as possible. As HVDC technology becomes a standard transmission solution due to its flexibility, it becomes an attractive asset for BSR. HVDC transmission is encouraged to reinforce the existing AC interconnected grid, create new long-distance interconnection, connect asynchronous grids, and integrate large amounts of renewable generation, all of which also enhance BSR options. This technical brochure investigates the use of VSC HVDC systems coupled with synchronous generation resources or external asynchronous transmission grids and touches on the utilization of VSC with variable renewable generation for BSR.
