HVDC converter platform optimisation
Background: In the 2020’s grid integration of vast amounts of offshore wind power to the grid is one of the main challenges for the power network industry. Some economically viable areas for offshore wind development are at the limits of what is achievable with existing HVAC technology using intermediate reactive power compensation. Innovation: Designs of HVDC platforms require further optimisation to enable cost reductions. Most designs require personnel to be stationed for prolonged periods of time requiring more ancillary services. It is known that this greatly increases OPEX costs. The size of offshore substations and converters also limits the manufacturers and ports capable of supplying them. Furthermore, converter insulation needs to be proven as reliable as it expensive and time-consuming to replace. Cooling systems are also required to prevent overheating, and uncertainty remains over how many converters are best to place on a single platform.
