“…Haarsma et al 2013), although it should be noted that there is considerable uncertainty about dynamical changes (Shepherd 2014). It is important to note that projected changes in the frequency of phenomena affecting variability of wind power generation, such as blocking and extratropical cyclones, are generally small when averaged over different climate models (Ohba et al 2016), and more uncertain than changes in the mean state (Masato et al 2013, Zappa et al 2013. However, there is agreement within the literature that climate models project a substantial decrease in winter storm frequency in the Mediterranean (Christensen et al 2013, Zappa et al 2013.…”

“…Japan is located in the mid‐latitudes between the Pacific Ocean and the Eurasian continent, where large synoptic‐scale atmospheric variabilities occur mainly due to developing and travelling of high/low pressure systems. The large synoptic‐scale variabilities can induce large uncertainties in the IBCs for mesoscale NWP models . Wind speed ramps are sensitive to the variabilities of synoptic‐scale atmospheres or local atmospheric circulations due to complex terrain.…”

Therefore, a mesoscale ensemble approach with multiple IBCs derived from a global ensemble forecast is beneficial to reduce uncertainties in predicting wind speed ramp events.…”

Application of mesoscale ensemble forecast method for prediction of wind speed ramps

et al. 2019

Sudden changes in wind speed, so‐called wind speed ramps, are a major concern for wind power system operators. The present study applies the mesoscale ensemble forecast method for the prediction of wind speed ramps at wind farms in Japan and evaluates the ability and utility of this method. The mesoscale ensemble forecast in this study (ENS21) consists of 21 members with a horizontal resolution of 10 km for a 5‐year period. The simulated results show that ENS21 produces better accuracy than the deterministic forecast with a horizontal resolution of 10 km (DET_L). On the other hand, the deterministic forecast with a horizontal resolution of 5 km (DET_H) also produces better accuracy than DET_L. From a practical perspective, however, the ENS21 is computationally expensive. Thus, the eight‐member mesoscale ensemble forecast (ENS8) with as same computational cost as a deterministic forecast with a horizontal resolution of 5 km (DET_H) is also evaluated. The simulated results show that ENS8 has almost same accuracy as ENS21 and DET_H in wind speed ramp forecasts. ENS8 has advantages over ENS21 and DET_H because ENS8 is computationally efficient and is able to benefit wind power operators with flexibility in the selection of probability thresholds for decision processes compared with a single. It can be concluded that the mesoscale ensemble forecast method is more useful for prediction of the wind speed ramp than the single deterministic forecast method with the same computational cost if the ensemble members are successfully selected.

“…Great efforts on safe, clean, and economic development have been made by the United States, Japan, the European Union, and other developed countries and some organizations. Some regions even put forward a series of energy consumption policies with respect to the continuous consumption of global energy . There's no concern about the pollutants (carbon dioxide and nitrogen) or the radioactive material leakage risks in the process of wind turbines' operation.…”

A review on China's wind power accommodation in the background of “Internet+” strategy

Summary The consumption of fossil fuel has resulted in global warming, environmental pollution, and many other crucial problems. Replacing fossil fuel with renewable energy has become an important issue over the recent decades. As a renewable clean energy, wind power is a relatively well‐developed and promising energy method for current technology development in China. Under the background of growing demand for electricity and enhancing awareness for environmental, the “Internet+ wind power” concept has emerged based on both the wind power's characteristics that renewable and non‐polluting, and the rapid development of the Internet in China. Through querying an amount of literature and information, this paper reveals the resource endowment and policy environment about wind power and energy Internet at first. Then, the PEST‐SWOT strategy analysis model is used to analyze the internalities (strengths and weaknesses) and the externalities (opportunities and threats) of “Internet+ wind power”. According to these results, the paper puts forward some measures (development and utilization, business mode) for wind power accommodation. Then some policy recommendations have been proposed. The government should provide favorable conditions for wind power grid with the “Internet+” technology innovation.
