The offshore wind farms that are being built today use an AC connection to shore and the distances to the shore are also quite moderate. This is a well-known technology and a natural step for the first off-shore wind farms. However in ten, years when the experiences from the first offshore wind farms have been evaluated and the next expansion starts, the alternatives with a DC grid will become cost-effective solutions. The future wind farms will becomes larger and will be situated at a farther distance from shore. The connection to the onshore transmission grid must be at a point with high short circuit capacity and the onshore distance, therefore is expected to be greater in the future.
The cost of power electronics will be significantly lower in the future and the losses will continue to decrease, so the advantages will outweigh the disadvantages.
