[0002] Wind power and the power system are closely connected. The volatility and intermittency of wind energy, which can cause fluctuations in wind power output and adversely affect power quality, safe and stable operation, and economic efficiency, must be considered. The importance of wind resource forecasting is self-evident, playing a crucial role throughout the entire lifecycle of a wind farm. Wind resource forecasting is a crucial decision-making tool during the development and construction phase of a wind farm. Accurate wind resource forecasts can reduce damage to wind turbines and components from extreme weather events, enabling wind farm operators to formulate appropriate maintenance plans and prepare for weather disasters. Compared to onshore wind power, offshore wind resources offer superior power generation efficiency, making the development of offshore wind power a crucial area of focus for renewable energy. However, due to limited offshore observation capabilities and significant spatial and temporal limitations, the lack of measured data presents a significant challenge in assessing and predicting offshore wind speeds. Consequently, a highly accurate and efficient offshore wind speed forecasting method is currently lacking.

[0024] The following describes the embodiments of the present application through specific examples. Those skilled in the art can easily understand the other advantages and effects of the present application from the content disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.
[0025] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. Therefore, the illustrations only show components related to the present application and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.
[0026] Numerical weather forecasting is the most common method for wind energy forecasting. For example, the Global Forecast System (GFS) can provide forecast results for major meteorological elements including wind fields around the world in the next few days. However, due to the imperfection of parameterization schemes, resolution limitations and insufficient representation of high-resolution features at the regional scale, this type of global numerical forecast system has relatively poor forecast capabilities for regional small-scale wind fields. The forecast error is particularly significant in offshore areas, which cannot meet the needs of actual development and construction of offshore wind power. Currently, regional high-resolution offshore wind speed forecasts are mostly based on mesoscale numerical models (Weather Research and Forecast, WRF for short). WRF is a numerical model used for meteorological forecasting and research. It is a high-resolution, non-static, non-hierarchical, and non-uniform atmospheric numerical model. The WRF model simulates atmospheric phenomena by dividing the Earth's atmosphere into horizontal grids and vertical layers, and solving atmospheric dynamics, thermodynamics, and hydrological cycle equations through discrete equations. This model is widely used in wind resource simulation and wind speed forecasting. The advantage of the WRF numerical model is that the physical process is clear. Even if there is less observation data, high-resolution regional data can be constructed by characterizing local thermodynamic processes. However, there are also problems such as large errors, difficulty in verifying prediction results, and high time cost.
[0027] At least to address the above-mentioned problems, an embodiment of the present application provides a wind speed prediction method, which includes: constructing a correction model based on a deep learning model to obtain a mesoscale driving field model; screening the mesoscale driving field model according to the mesoscale driving field model and data information to obtain a screened mesoscale driving field model; obtaining a mesoscale prediction result based on the screened mesoscale driving field model; and interpolating the mesoscale prediction result to obtain a downscaled prediction result.
[0028] In this embodiment, a deep learning model calibration model is used to obtain a mesoscale driving field model. This model is then filtered using data information to obtain a mesoscale driving field model with higher prediction accuracy. A mesoscale prediction result is obtained based on the filtered mesoscale driving layer, and the mesoscale prediction result is then processed to obtain a downscaled prediction result. This approach can obtain more accurate downscaled prediction results and improve the efficiency of wind speed prediction.
[0029] The wind speed prediction method described in this application can be applied to end-to-cloud interaction scenarios. Figure 1 shows a schematic diagram of the structure of an end-to-cloud interaction scenario in the implementation method described in an embodiment of this application. As shown in Figure 1, the end-to-cloud interaction system 1 includes a terminal 10 and a cloud server 11. The terminal 10 and the cloud server 11 can communicate with each other, and the communication method is not limited to wired or wireless.
[0030] The terminal 10 may be mobile or fixed. For example, the terminal 10 may be a wireless terminal or a wired terminal. A wireless terminal may refer to a device with wireless transceiver capabilities and may be deployed indoors, outdoors, or in offshore wind farms. The terminal 10 may be a mobile phone, a tablet computer, a laptop computer, or the like, without limitation.
[0031] The cloud server 11 may include one or more servers, or one or more processing nodes, or one or more virtual machines running on the server. The cloud server 11 may also be called a server cluster, a management platform, a data processing center, etc., which is not limited in the embodiments of the present application.
[0032] The technical solutions in the embodiments of the present application will be described in detail below with reference to the accompanying drawings in the embodiments of the present application.
[0033] The following embodiments of the present application provide a wind speed prediction method, which can be implemented, for example, by the cloud server 11 shown in Figure 1. Figure 2 shows a flow chart of the wind speed prediction method according to an embodiment of the present application. As shown in Figure 2, the wind speed prediction method includes steps S11 to S14.
[0034] Step S11: constructing a calibration model based on the deep learning model to obtain a mesoscale driving field model. The calibration model is obtained by adjusting the parameters of the deep learning model. The mesoscale driving field model (Weather Research and Forecast, WRF) is a numerical model used for weather forecasting and research.
[0035] Step S12: Filter the mesoscale driving field model based on the mesoscale driving field model and the data information to obtain a filtered mesoscale driving field model. The data information includes multi-source data such as satellite remote sensing data, site observation data, and reanalysis data. Optionally, the reanalysis data is a dataset obtained by quality control and assimilation of observation data (including ground observations, satellites, radar, soundings, buoys, aircraft, ships, etc.).
[0036] Step S13: obtaining a mesoscale prediction result based on the filtered mesoscale driving field model, wherein the mesoscale prediction result is a mesoscale wind speed prediction result.
[0037] In some possible implementations, Figure 3 shows a schematic diagram of an implementation of an embodiment of the present application. The screened mesoscale driving field model performs two-layer bidirectional nesting on the target area to obtain the mesoscale prediction results. The parent area in the bidirectional nesting provides boundary conditions for the child area, and the calculation results of the child area will be fed back to the parent area. As shown in Figure 3, the large square is the parent area, the small square is the child area, and the central longitude and latitude of the parent area and the child area are consistent, for example, 11.10° north latitude and -73.52° east longitude. The grid point distance of the parent area is set to 9 kilometers, and the total number of grid points is 75,922, so that the two-layer nesting resolution of the screened mesoscale driving field model is 9 kilometers and 3 kilometers, respectively, thereby obtaining high temporal and spatial resolution (hourly, 3-9 kilometers) prediction results of the target area.
[0038] It should be noted that the above is only one possible implementation method of the embodiment of the present application, and the present application is not limited thereto.
[0039] Step S14: performing interpolation processing on the mesoscale prediction result to obtain a downscaled prediction result.
[0040] In this embodiment, a deep learning model calibration model is used to obtain a mesoscale driving field model. The mesoscale driving field model is then filtered using data information to obtain a mesoscale driving field model with higher prediction accuracy. A mesoscale prediction result is obtained based on the filtered mesoscale driving field model. The mesoscale prediction result is then processed to obtain a downscaled prediction result. This approach can obtain more accurate downscaled prediction results and improve the efficiency of wind speed prediction.
[0041] In one embodiment of the present application, the parameters of the loss function of the correction model include the difference in wind speed between adjacent moments of the input data, and the difference in wind speed between adjacent moments of the input data is obtained using a momentum equation.
[0042] In one embodiment of the present application, the parameters of the loss function also include: input data, model prediction results, and the difference in wind speeds at adjacent moments of the model prediction results.
[0043] In some possible implementations, the input data is reanalysis data. First, the data of the global ensemble forecast system is obtained as the driving data of the mesoscale driving field model. Then, according to the ERA5 (European Centre for Medium-Range Weather Forecasts Reanalysis v5) reanalysis data and the FNL (Finally Opera Global Analysis) reanalysis data, a correction model is constructed based on the deep learning model to obtain the mesoscale driving field model. In the process of constructing the correction model, the momentum equation is combined to perform physical constraints on the wind speed characteristics. Optionally, the input data of the deep learning model is a forecast product data set using two adjacent moments, and the output data of the deep learning model is the model prediction result. The calculation formula of the loss function of the deep learning model is:
[0044] Where g1(x) is the prediction result of the deep learning model, y1 is the prediction result of the input data, g2(x) is the difference in wind speed between two adjacent moments calculated based on the momentum equation, y2 is the difference in wind speed between two adjacent moments calculated based on the prediction result of the deep learning model, i is a grid point, and n is the total number of grid points. The calculation method for the difference in wind speed between two adjacent moments based on the momentum equation is:
[0045] in, is the advection term, is the pressure gradient term, is the Coriolis force term.
[0046] In an embodiment of the present application, the momentum equation is used to construct the loss function of the deep learning model, so that the correction model obtained can have a stronger constraint effect on the correction of low-level wind speed based on the momentum propagation principle of mid- and high-level wind speed and low-level wind speed.
[0047] Figure 4 is a schematic flow chart of the wind speed prediction method according to an embodiment of the present application. As shown in Figure 4 , step S12 includes steps S121 to S123.
[0048] Step S121: Acquire a parameter scheme for the mesoscale driving field model based on data information, wherein the data information includes reanalysis data, satellite remote sensing data, and a small amount of site observation data.
[0049] Step S122: using the parameter scheme to obtain the simulated wind speed of the mesoscale driving field model.
[0050] Step S123 , performing screening according to the simulated wind speeds and the observed wind speeds to obtain the screened mesoscale driving field model.
[0051] In the embodiment of the present application, a multi-source data acquisition parameter solution is adopted. The simulation accuracy of the mesoscale driving field model obtained in this way is higher, and the simulated wind speed obtained is more accurate.
[0052] In one embodiment of the present application, screening according to each of the simulated wind speeds and the observed wind speeds includes obtaining the root mean square error between the simulated wind speed and the observed wind speed, and obtaining the screened mesoscale driving field model according to the root mean square error with the smallest value.
[0053] In some possible implementations, a parameter scheme for the mesoscale driven field model is obtained based on the data information, a simulated wind speed of the mesoscale driven field model is obtained based on the parameter scheme, and the simulated wind speeds are screened based on the observed wind speeds to obtain the screened mesoscale driven field model. Optionally, the root mean square error (RMSE) between the simulated wind speed and the observed wind speed is calculated by comparing the simulated wind speed with the observed wind speed. The formula for calculating the RMS SE between the simulated wind speed and the observed wind speed is:
[0054] Where M is the output result of the mesoscale driving field model, Station is the site result, Remote is the remote sensing data, Reanalysis is the reanalysis data, i is the i-th grid point, and a, b, and c are the weights of the three root mean square errors, respectively.
[0055] Optionally, the weights a, b, and c in the formula for calculating the root mean square error are 0.6, 0.2, and 0.3, respectively. The filtered mesoscale driving field model is obtained based on the parameter solution with the smallest root mean square error value. A mesoscale prediction result is obtained based on the mesoscale driving field model.
[0056] Figure 5 is a flow chart of the wind speed prediction method according to an embodiment of the present application. As shown in Figure 5 , step S14 includes the following steps S141 to S144 .
[0057] Step S141: Acquire multiple interpolation schemes.
[0058] Step S142: Obtain the downscaled prediction result using the interpolation scheme.
[0059] Step S143 , performing screening according to the downscaled prediction results to obtain a screened interpolation scheme.
[0060] Step S144: Interpolate the mesoscale prediction result using the filtered interpolation scheme to obtain a downscaled prediction result. Optionally, the mesoscale prediction result is a wind speed prediction result with an accuracy of 3 to 9 kilometers, while the downscaled prediction result is a wind speed prediction result with an accuracy of 1 kilometer. The downscaled prediction result at the 1 kilometer scale has higher prediction accuracy than the mesoscale prediction result at the 3 to 9 kilometer scale.
[0061] In some possible implementations, multiple interpolation schemes are obtained, including an inverse distance weighting scheme, a bilinear interpolation scheme, a Kriging interpolation scheme, and a radial basis function scheme, but the present application is not limited thereto. Each of the interpolation schemes is used to perform spatial interpolation on the area where the downscaled prediction results need to be obtained. Specifically, the mesoscale prediction results of 3 to 9 kilometers are interpolated to a 1 kilometer scale, and the root mean square error between the results obtained by each interpolation scheme and the actual observed wind speed of the mesoscale driving field model is calculated. The interpolation scheme with the smallest root mean square error value is screened and obtained as the screened interpolation scheme. The calculation formula for the root mean square error is:
[0062] Where Intep is the interpolated result, WRF_1km is the simulated wind speed result of the mesoscale driving field model WRF at a scale of 1 km, i is the i-th grid point, and n is the total number of grid points.
[0063] In the embodiment of the present application, the actual observed wind speed at the kilometer level of the mesoscale driving field model is compared with the simulated wind speed obtained by multiple interpolation schemes to obtain a screened interpolation scheme, thereby achieving rapid encryption of the area where the downscaled prediction results need to be obtained.
