ABB has commissioned the world's first HVDC back-to-back system for transmission using voltage source converter technology.
The firm has successfully commissioned an HVDC Light system that will control the flow of power and enhance grid stability in the US state of Michigan.
ABB designed, supplied and installed the 200 MW back-to-back HVDC Light station in Upper Michigan. It comprises two HVDC converters connected directly to each other, without any DC transmission line, making it possible to fully control the power transfer through the connection.
The system controls the power flow between the upper and lower peninsulas of Michigan. It also provides dynamic voltage support to increase regional grid reliability and enable the integration of additional wind generation.
