Abstract |
Offshore wind power has been attracting attention as a key energy source for the carbon neutralization strategy, and has the advantage of good wind resources compared to onshore wind power, and is easy to large-scale. However, the initial installation and maintenance costs of large-scale offshore wind farms are very high, so it is important to minimize the initial investment cost. Although there are preliminary studies on the economic evaluation of the inter-array of offshore wind farms in Korea, there is still a lack of research on the inter-array that considers the economic evaluation and reliability evaluation together. In this paper, therefore, the current carrying capacity and short-circuit current of a 60MW offshore wind farm with 95 mm are compared to construct the inter-array of the offshore wind farm with the new minimum size submarine cable. The inter-array is then optimized using binary integer programming model using the Bentley-Ottmann algorithm to avoid double-crossing arcs. The economic evaluation of the inter-array is conducted by comparing the installation cost and loss cost, and the reliability evaluation considering equipment failure. Then, the optimal inter-array layout of offshore wind farm with both economic evaluation and reliability evaluation is studied and reviewed. |
