![]() ![]() The wind varies on both spatial and temporal scales, ranging from small features existing for a few seconds to large and slowly evolving climatological patterns. These numbers underline the need to take advantage of the floating offshore wind energy source with a view to addressing the continuous growth in global energy consumption.Įxploiting the offshore wind energy potential introduces a number of challenges, one of which is the variable nature of the energy source. ( 2018) has found the global offshore wind energy potential to be 329.6 TWh, with over 50 % of this potential being in deep waters ( >60 m). ![]() Offshore wind power, and especially floating offshore wind power, is only in an initial phase compared to other more mature and developed energy sources. This is a desired development due to, among others things, emission goals that are linked to mitigation of global warming. Renewable power generation from various sources is continuously increasing. The average atmospheric weather pattern resulting in wind speed that is too low (too high) to produce wind power is associated with a high-pressure (low-pressure) system near the production sites. Increasing the array size further reduces the risk, but to a lesser extent. The risk of no wind power production for a given hour is reduced from the interval 8.0 %–11.2 % for a single site to under 4 % for two sites. We find that both the wind power variability and the risk of not producing any wind power decrease significantly with an increasing array of connected sites. Typical large-scale atmospheric situations resulting in long term shutdown periods are identified. Along with the wind power smoothing effect, we explore the risk probability of the occurrence and duration of wind power shutdown due to too low or high winds. ![]() The degree of mitigation is examined by connecting different configurations of the sites. Mitigation of wind power intermittency is investigated using a hypothetical electricity grid. We address the well-known intermittency problem of wind power for five locations along the Norwegian continental shelf. This study uses a unique set of hourly wind speed data observed over a period of 16 years to quantify the potential of collective offshore wind power production. ![]()
