Offshore wind power farm is one of the promised renewable energy due to the advantages such as higher average wind speeds and the availability of large-scale compared to onshore. However, there are several challenges such as the uncertainty of wind and the high installation cost of the facilities which depend on geographical factors. Therefore, a three-stage methodology is proposed to determine the design of offshore wind power farms considering wind uncertainty and geographic factors. First, installation costs of facilities and constraints are specified. Second, candidate locations are selected and geographical information is organized. Finally, a stochastic optimization model which aims to minimize the unit cost (installation cost over power generation) and determine the location of the wind turbine, the array of cables, and the location of the substation is formulated. A case study was performed according to the 6th regional energy plan in Jeju Island. As a result, an offshore wind farm with a unit cost similar to that of an existing wind farm could be implemented in Jeju Island. |
