The global wind energy sector is still developing rapidly [1, 2]. For example, EU countries plan to develop large scale offshore wind farms, 10000 MW by 2010, including an expected offshore wind power capacity of 4000 MW in the UK. The target for installed wind energy is 5500 MW in Denmark by 2030, out of which 4000 MW will be offshore.

A variety of wind turbines (WTs) have been designed and installed in wind farms for converting wind power to electricity. Most turbine designs rely on the traditional wind power profile, as shown in , mapping Figure 1 various wind speeds to the output power. As can be seen, the domain is divided into four regions. In Region I,

Wind farm control can be used to increase wind energy e ciency by maximizing power in wind farms that are already installed. In can also be used to mitigate structural loads to maximize the lifetime of the turbines and better integrate wind energy into the energy market. Currently, turbines in a wind farm are operated to maximize their own .

the wind blows stronger and its flow is more consistent. By using FOW, developers can make use of larger areas avoiding wake effects from nearby wind turbines or other wind farms. Also, larger wind turbines that will be developed in the near future, for example 12-15 MW, can be installed on FOW substructures. The combination of larger wind

Based on the 2015 wind development goal, the State of Maine has met 17.28 percent of its wind energy goals with 345.5 megawatts (MW) of installed land-based wind capacity. wind would need to be installed by 2015. There are currently no off-shore wind projects in operation in Maine.

This implies a total share of 45% for wind energy, with 27% coming from onshore wind, 13% from fixed-bottom and 5% from floating wind technologies. For floating wind, this is projected to include an 80% reduction in the levelized cost of energy (LCOE) from its current value, compared to a 44% reduction in LCOE for fixed-bottom offshore wind.
