HVDC Connection of Offshore Wind Farms to theTransmission System

introduction
Introduction
  • This paper presents a technical and economic analysis to evaluate the benefits and drawbacks of grid connecting offshore wind farms through a dc link.
economic analysis comparison of the connection options
ECONOMIC ANALYSIS: COMPARISON OF THE CONNECTION OPTIONS
  • O&M: operation and maintenance
  • ENS : the value of losses and of energy not supplied
economic analysis comparison of the connection options1
ECONOMIC ANALYSIS: COMPARISON OF THE CONNECTION OPTIONS
  • This especially impacts the economics of the 100-MW wind farm.
  • Economic assessment includes sensitivity analyses of parameters, which could impact the 100-MW wind farm: distance, component costs, dc converter reliability, and dc converter losses.
conclusion
CONCLUSION
  • For all the case studies, the HVDC solution is more expensive than the ac, partly because of higher total investment costs at the considered connection distance of 60 km.
  • Nevertheless, the results of sensitivity analyses performed for various parameters (connection distance, cost of cable protection, and cost and reliability of converter stations) show that HVDC appears to be the cheapest option to connect a 100-MW wind farm at distances greater than 90 km to the shore.
conclusion1
CONCLUSION
  • Evaluations performed within this research activity and the present experience with VSC-HVDC connection of offshore oil/gas platforms allows us to believe that HVDC is a promising technology with growth potential for applications in the connection of offshore wind farms.
