Description

Technical Field

[0001] This invention relates to the field of new energy development technology, specifically to a method and apparatus for locating new energy development sites in mountainous and valley areas. Background Technology

[0002] Mountainous and valley regions possess abundant hydropower, wind power, and solar power resources. Among these, wind and solar resources are known for their inherent volatility. These characteristics, to some extent, reduce the utilization rate of renewable energy through transmission channels such as ultra-high-voltage power lines, becoming a major bottleneck in the development and utilization of wind and solar resources. In mountainous and valley regions, the rapid regulation capability of hydropower resources provides a unique advantage for the integrated development of wind, solar, and hydropower, which is considered a key strategy for improving the development and utilization level of renewable energy. Through this integrated development model, the instability of wind and solar resources can be effectively mitigated, the energy structure optimized, and the overall utilization level of renewable energy improved.

[0003] However, due to the complex terrain of mountainous and valley areas, the development of wind, solar, and hydropower resources in these regions faces significant challenges. Related technologies typically base new energy development locations on a single type of solar or wind power. However, the energy fluctuations of solar and wind power are substantial. Therefore, roughly determining new energy development locations based on a single type of solar or wind power not only fails to comprehensively utilize various new energy sources but also fails to accurately pinpoint suitable development locations. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] According to an embodiment of the present invention, a method embodiment for locating new energy development sites in mountainous and valley areas is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0051] This embodiment provides a method for locating new energy development sites in mountainous and valley areas, which can be used on mobile terminals such as mobile phones and tablets. Figure 1 This is a flowchart of a method for locating new energy development sites in mountainous and valley areas according to an embodiment of the present invention, such as... Figure 1 As shown, the process includes the following steps:

[0052] Step S101: Simulate the target mountain and valley area using meteorological and hydrological coupling software, and generate corresponding target terrain grid data.

[0053] Specifically, the meteorological-hydrological coupling software in this embodiment can be WRF-Hydro software, which supports high-resolution numerical models and can improve the accuracy of the assessment. Therefore, this embodiment simulates mountain valley topography based on WRF-Hydro software, and performs long-term simulations of the mountain valley and its surrounding areas to determine the target mountain valley region.

[0054] Furthermore, the WRF-Hydro software was used to conduct long-term simulations of the mountain valleys and their surrounding areas to obtain hourly resolution data on near-surface air temperature, near-surface air pressure, near-surface wind speed, downward solar radiation from the surface, and natural river flow. All of these data belong to the target terrain grid data.

[0055] Step S102: Obtain the total wind energy resource development amount and the total solar energy resource development amount corresponding to each grid in the target terrain grid data.

[0056] In an optional implementation, step S102 above, obtaining the total amount of solar energy resource development corresponding to each grid in the target terrain grid data, includes:

[0057] Step a1: Based on meteorological and hydrological coupling software, obtain the average solar energy resource density and grid area of ​​each grid in the target terrain grid data.

[0058] In a specific implementation, step a1, based on meteorological and hydrological coupling software, obtains the average solar energy resource density on each grid in the target terrain grid data, including:

[0059] Step a11: Using meteorological and hydrological coupling software, obtain the hourly simulation of surface downward solar radiation, the total simulation duration of surface downward solar radiation, and the annual simulation duration for each grid in the target terrain grid data.

[0060] Step a12: Based on the hourly simulation of surface-downward solar radiation, the total simulation duration of surface-downward solar radiation, and the annual simulation duration in each grid of the target terrain grid data, calculate the average solar energy resource density in each grid of the target terrain grid data.

[0061] Specifically, in each grid of the target terrain grid data, the simulated hourly downward solar radiation S at the Earth's surface is obtained using WRF-Hydro software. i (unit: W m) -2 Take the average and calculate the average solar energy resource density on the corresponding grid of the new energy development area. (unit: W m) -2 Specifically, it can be calculated using the following formula:

[0062]

[0063] Where n is the total simulated duration of solar radiation downwards from the Earth's surface, and 8765.82 is the annual simulated duration of solar radiation downwards from the Earth's surface (an average number of hours per year).

[0064] Step a2: Calculate the product of the average solar energy resource density and the grid area of ​​each grid in the target terrain grid data to obtain the total amount of solar energy resource development for each grid in the target terrain grid data.

[0065] Specifically, for each grid within the target mountainous valley region, the average solar energy resource density of that grid is calculated. Multiply by the grid area to get the total amount of solar energy resources to be developed on each grid.

[0066] In an optional implementation, step S102 above, obtaining the total wind energy resource development amount corresponding to each grid in the target terrain grid data, includes:

[0067] Step b1: Based on meteorological and hydrological coupling software, obtain the average wind power density and grid area of ​​each grid in the target terrain grid data.

[0068] In a specific implementation, step b1, based on meteorological and hydrological coupling software, obtains the average wind power density on each grid in the target terrain grid data, including:

[0069] Step b11: Using meteorological and hydrological coupling software, obtain the near-surface wind speed, air pressure, mixing ratio, and actual temperature for each grid in the target terrain grid data on an hourly basis, and calculate the hourly wind power density.

[0070] Step b12: Obtain the total simulation duration and annual simulation duration for hourly near-surface wind speed simulation on each grid in the target terrain grid data.

[0071] Step b13: Calculate the average wind power density on each grid in the target terrain grid data based on the hourly wind power density, the total simulation duration of hourly near-surface wind speed simulation on each grid in the target terrain grid data, and the annual simulation duration.

[0072] Specifically, in each grid within the new energy development area, the hourly near-surface wind speed v (unit: m / s) was simulated using WRF-Hydro software. -1 ), air pressure p (unit: Pa), mixing ratio r (unit: kg) -1 Given the actual temperature T (in K), calculate the hourly wind power density E. w (unit: W m) -2 Specifically, it can be calculated using the following formula:

[0073]

[0074] Where ρ is the air density (unit: kg m³) -3 ), R d =287.04JK -1 kg -1 T is the gas constant for dry air. v This is the virtual temperature (unit: K).

[0075] Based on this, the hourly wind power density E w The average wind power density in each grid within the new energy development area is calculated by averaging. Specifically, it can be calculated using the following formula:

[0076]

[0077] Where m is the total simulation duration of surface wind speed, 8765.82 is the annual simulation duration of near-surface wind speed (an average of hours per year), and this annual simulation duration of near-surface wind speed can be equal to the total simulation duration of solar radiation directed downwards from the Earth's surface, E w,iLet be the average wind power density at time i.

[0078] Step b2: Calculate the product of the average wind power density and the grid area of ​​each grid in the target terrain grid data to obtain the total wind energy resource development amount of each grid in the target terrain grid data.

[0079] Specifically, for each grid in the target terrain grid data, the average wind power density on that grid is... Multiply by the grid area to get the total amount of wind energy resources to be developed in each grid.

[0080] Step S103: Select the maximum value from the total wind energy resource development and total solar energy resource development for each grid as the total new energy development for that grid, and take the new energy that generates the total new energy development as the new energy development type for that grid.

[0081] Specifically, for example, if the total wind energy development capacity of the first grid in the target terrain grid data is 60 kW and the total solar energy development capacity is 38.9 kW, then the total wind energy development capacity will be taken as the total new energy development capacity of the first grid, and wind energy will be taken as the new energy development type of the first grid. Similarly, if the total wind energy development capacity of the second grid in the target terrain grid data is 58.3 kW and the total solar energy development capacity is 78 kW, then the total solar energy development capacity will be taken as the total new energy development capacity of the second grid, and solar energy will be taken as the new energy development type of the second grid.

[0082] Step S104: Using meteorological and hydrological coupling software, obtain the new energy fluctuation amount corresponding to each grid in the target terrain grid data.

[0083] Specifically, the new energy fluctuation here can be the standard deviation of the energy resource quantity of each grid in the target terrain grid data over many years, that is, the average value of the total energy development over many years.

[0084] Step S105: Generate an energy volatility envelope map based on the new energy fluctuation amount, new energy development type and total new energy development amount corresponding to each grid in the target terrain grid data.

[0085] Specifically, each grid in the target mountainous and valley region corresponds to a specific total amount and type of new energy development. For example... Figure 2 The diagram shown is an energy fluctuation envelope diagram of an embodiment of this disclosure, with the horizontal axis representing the total amount of new energy development and the vertical axis representing the fluctuation amount.

[0086] Step S106: Using meteorological and hydrological coupling software, obtain the total hydropower resource development amount at the valley outlet in the target mountain valley area, and integrate the total hydropower resource development amount into the energy fluctuation envelope diagram.

[0087] Specifically, in the target mountain valley region, natural flow data and riverbed gradient of the mountain valley can be obtained through long-term simulation using WRF-Hydro software, thereby assessing and calculating the total exploitable hydropower resources.

[0088] For example, at the valley outlet of the target mountain valley region, the hourly natural flow rate Q (unit: m³) was simulated using WRF-Hydro software. 3 s -1 ), calculate the hourly hydropower E of the valley. h (Unit: W)

[0089]

[0090] Where, ρ = 1000 kg m -3 Given the density of water, g = 9.8 mS / s. -2 Let h be the acceleration due to gravity, and h be the slope of the river valley (in meters).

[0091] Total exploitable hydropower resources in mountain valleys ( The unit W represents hourly hydropower E. h The average.

[0092]

[0093] Where g is the total simulation duration for hourly natural flow, 8765.82 is the annual simulation duration for hourly natural flow (an average of hours per year), and E h,i Let be the hourly hydropower of the valley at time i.

[0094] Furthermore, all grids within the mountain valleys are sequentially added to the target terrain grid data. The hydropower and wind / solar resources in the target terrain grid data are then summed to obtain the total hydropower, wind, and solar energy resources, until all grids within the valleys are included in the target terrain grid data. Then, the total renewable energy development amount for each grid in each target terrain grid is calculated, and a curve is plotted with the total amount on the x-axis and volatility on the y-axis. Figure 2 Energy volatility envelope diagram in the data.

[0095] Step S107: Based on the transmission capacity of the target mountain and valley region, select the optimal location for new energy development from the integrated energy volatility envelope map.

[0096] Specifically, the energy volatility envelope diagram after integrating hydropower in the target mountain valley region can contain multiple rising and falling intervals. In the rising intervals, the larger the total development volume, the greater the volatility; in the falling intervals, the larger the total development volume, the smaller the volatility. There can be multiple rising and falling intervals. Based on the capacity of the transmission channels, such as ultra-high voltage lines (transmission channel capacity), the optimal location for new energy development is determined, ensuring that the development volume does not exceed the transmission channel capacity. Within the target mountain valley region, avoiding the rising volatility intervals, the optimal location for new energy development is selected within the falling intervals of the variation curve based on the total development volume and volatility of new energy resources.

[0097] In one specific implementation, step S106, based on the transmission capacity of the target mountain valley region, selects the optimal location for new energy development from the merged energy volatility envelope, including:

[0098] Step c1: Obtain the capacity of the external transmission channels in the target mountainous and valley areas.

[0099] Step c2: Obtain the total amount of new energy development corresponding to each trough in the merged energy fluctuation envelope diagram.

[0100] Step c3: If the total amount of new energy development corresponding to each trough is less than or equal to the transmission capacity of the target mountain valley area, the location of the trough shall be taken as the optimal location for new energy development.

[0101] Specifically, the transmission channel capacity in this embodiment can be a reference capacity. The fused energy volatility envelope map includes multiple troughs, and the total renewable energy development amount corresponding to each trough is obtained. The reason for obtaining the total renewable energy development amount corresponding to each trough is to avoid terrain locations corresponding to areas of rising volatility in the target mountainous and valley regions. If the total renewable energy development amount corresponding to each trough is greater than the transmission channel capacity of the target mountainous and valley region, it indicates that the terrain location of that trough is not suitable as the optimal location for renewable energy development.

[0102] The method for locating new energy development sites in mountainous and valley areas in this embodiment of the present disclosure comprehensively considers solar energy, wind energy, and hydropower resources in the target mountainous and valley areas. This is conducive to making full use of various energy sources, thereby reducing the fluctuation of energy output and improving the utilization level of transmission channels, which is of great significance for promoting the development of clean energy.
