A method and system for determining pumped storage reservoir area parameters based on carbon emissions

Abstract

The present application discloses a method and system for determining parameters of a pumped storage reservoir area based on carbon emissions, and relates to the technical field of electrical digital data processing. The method continuously iterates and updates the difference between the excavation volume and the filling volume, so that the relative position between the comparison surface and the reference surface is continuously updated and changed. When the relative position is continuously updated and changed, the global optimization is synchronously performed to update and iterate the carbon emissions, so that the entire model is updated in real time. After the iteration based on carbon emissions is completed, the various determined parameters of the model can be obtained, so that the difference between the excavation and filling volume reaches the expected design requirements or the minimum value. The dam top elevation obtained at this time is the elevation value that satisfies the excavation and filling balance of the reservoir basin, thereby achieving excavation and filling at the same time, effectively reducing the subsequent engineering volume, and also minimizing the carbon emissions generated by earth and stone transportation.

Description

Technical Field

[0001] The present application relates to the field of electrical digital data processing technology, and in particular to a method and system for determining pumped storage reservoir area parameters based on carbon emissions. Background Art

[0002] Pumped-storage hydropower stations, also known as storage hydropower stations, utilize electricity generated during low-load periods to pump water to an upper reservoir and release it to a lower reservoir for power generation during peak load periods. Pumped-storage hydropower stations can convert excess electricity generated during periods of low grid load into high-value energy during peak periods. They are also suitable for frequency and phase modulation, stabilizing the frequency and voltage of the power system. They are also suitable for emergency standby use and can improve the efficiency of thermal and nuclear power plants within the system.

[0003] As a mature energy storage technology, pumped-storage power stations can perform multiple functions in power systems, including peak-load shifting, energy storage, frequency regulation, phase modulation, emergency backup, and black start. Currently, there is no scientific and unified accounting system or industry standards for the contribution of pumped-storage power stations to carbon emissions reduction.

[0004] At present, when determining the design parameters of the reservoir area of a pumped-storage power station, most of them use the balance of cut and fill as a constraint condition. There is no calculation method that uses minimum carbon emissions as a constraint condition. Therefore, studying a calculation method for the cut and fill parameters of the reservoir area of a pumped-storage power station based on carbon emissions will not only help improve the economic benefits of the power station, but also help promote the realization of carbon emission reduction goals.

The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0072] like Figure 1 As shown, this embodiment provides an embodiment of a method for determining pumped storage reservoir area parameters based on carbon emissions. In this embodiment, the pumped storage reservoir area is applied to a pumped storage power station to be constructed in a preset area.

[0073] Preferably, the preset area is the site for the pumped storage power station to be constructed, which is mostly used in mountains with high and low terrain differences, providing the necessary foundation for pumped storage.

[0074] Specifically, the method for determining the parameters of the pumped storage reservoir area includes the following steps:

[0075] Step S1: Obtain the original terrain triangulated surface of the pumped storage power station to be built, and establish a reservoir basin design surface model through Civil 3D according to a preset strategy. The reservoir basin design surface model includes the dam axis, dam crest elevation, reservoir basin surface, cut surface, and fill surface.

[0076] Preferably, both the excavation surface and the fill surface are unique modeling methods of Civil 3D. These two surfaces can be directly selected in the option bar of Civil 3D. The specific creation details are handled by Civil 3D itself and will not be repeated in this embodiment.

[0077] It's worth noting that in actual operation, there's a problem with selecting the top and bottom orientation of the surfaces in fill and cut volumes. The fill volume is the area enclosed by the original surface above and the design surface below (a misconception: the fill volume has the design surface above and the original surface below, so the top and bottom conditions are also selected). The cut volume is the area enclosed by the original surface below and the design surface above.

[0078] Step S2: The original terrain triangulated surface is used as a reference surface, and the reservoir basin design surface model is used as a comparison surface.

[0079] Preferably, the reservoir basin refers to the range submerged below the dead water level of the reservoir, which is equivalent to the submerged area above the reservoir bottom to the bottom plate of the sluice gate. The reservoir bank is also used to describe the reservoir water level. The reservoir bank refers to the area submerged by the reservoir capacity between the dead water level and the check water level.

[0080] Preferably, this embodiment can take advantage of the ease of operation of Civil 3D to directly fill in various design parameters in Civil 3D (which can be understood as the various parameters in steps S1 to S9, for example: dam parameters, excavation parameters, fill parameters, main water level characteristics, etc. in the main design parameters), and directly solve the engineering parameters of the preset area (such as main engineering quantities, slope characteristics, reservoir basin characteristics, etc.) through the Civil 3D toolkit.

[0081] Step S3: obtaining the height difference between the comparison surface and the reference surface, and defining the portion where the height difference is greater than zero as the fill portion, and the portion where the height difference is less than zero as the cut portion.

[0082] Step S4, obtaining the optimal route of the cut surface and the fill surface, and obtaining the distance length of the optimal route and the height difference of the maximum point of the optimal route.

[0083] Preferably, the elevation difference of the maximum point of the optimal route is the difference between the highest point in elevation and the lowest point in elevation in the optimal route. This embodiment takes into account that continuous uphill climbing of the transport vehicle at a uniform speed will accelerate the fuel consumption rate, while continuous downhill climbing will also slow down the fuel consumption rate. The ups and downs in the middle are offset, and only the highest point to the lowest point is considered.

[0084] Step S5: Evaluate the total carbon emissions of transporting all the earth and stone from the excavation part to the filling part based on the distance length and the height difference of the maximum point.

[0085] Preferably, the carbon emissions in the excavation and filling project are evaluated, mainly including the carbon emissions from the use of machinery and the transportation of earth and stone. The carbon emissions calculation formula is as follows (1):

[0086] E carbon =E machine +E transport +E material (1), where:

[0087] ① Carbon emissions from machinery use mainly come from the combustion of fossil fuels, and the calculation formula is as follows:

[0088] E machine =V × EF× CO2.

[0089] E machine is the total carbon emissions from machinery use.

[0090] V is the total fuel consumption (liters or cubic meters) of each machine during the calculation period.

[0091] EF is the emission factor of the corresponding fuel (usually expressed in carbon dioxide equivalent, in g·CO2 / liter or g·CO2 / cubic meter).

[0092] CO2 is the conversion factor for carbon dioxide, usually 1.

[0093] ②The carbon emissions from earthwork transportation can be calculated using the following formula:

[0094] E transport =Σ(D × EF × CO2).

[0095] E transport is the total carbon emissions from earthwork transportation.

[0096] D is the distance travelled by each mode of transport during the calculation period (in kilometers).

[0097] EF is the emission factor of the corresponding fuel (usually expressed in carbon dioxide equivalent, in g·CO2 / liter or g·CO2 / cubic meter).

[0098] CO2 is the conversion factor for carbon dioxide, usually 1.

[0099] In step S6, the volume value of the filling part is defined as positive, and the volume value of the excavation part is defined as negative, and the volume value of the filling part and the volume value of the excavation part are summed to obtain a sum value.

[0100] Preferably, the closer the sum value is to 0, the better.

[0101] Step S7: Iterate the sum values through a global optimization algorithm to minimize the total carbon emissions.

[0102] Step S8: Obtain the sum value corresponding to the minimum value, and the volume value of the filling part and the volume value of the excavation part corresponding to the sum value, and define them as the final filling volume and the final excavation volume.

[0103] In step S9, the final fill volume and the final cut volume are input into the reservoir basin design surface model, and the dam axis, dam crest elevation, reservoir basin surface, cut surface, and fill surface are updated through Civil 3D to obtain the determined parameters of the pumped storage reservoir area.

[0104] Furthermore, in step S1, the original terrain triangulated surface of the pumped storage power station to be constructed is obtained, and a reservoir basin design surface model is established using Civil 3D according to a preset strategy. The reservoir basin design surface model includes the dam axis, dam crest elevation, reservoir basin surface, cut surface, and fill surface, including:

[0105] Step S11: obtaining digital elevation data of a preset area, inputting the digital elevation data into Civil 3D, and creating an original terrain triangulated surface through the surface operation function of Civil 3D.

[0106] Preferably, digital elevation data can be obtained directly from public channels (national high-precision 5m-12m-30m DEM terrain data download).

[0107] Preferably, Global Mapper has good compatibility with Civil 3D. In this embodiment, the DEM (digital elevation model) is preferably loaded into Global Mapper for preprocessing.

[0108] Specifically, after loading the DEM into Global Mapper and before generating contour lines, the DEM generally needs to be clipped to extract the DEM of the target area. The target area data can be output using LSV (LocaSpaceViewer, a three-dimensional digital earth software that integrates imagery and three-dimensional terrain online services such as Google Earth and Tiandi Map. The underlying development technology uses C++ and OpenGL. The software can quickly browse, measure, analyze, and annotate three-dimensional geographic information data and oblique photography real-life data.) and then saved as KML (KML files are landmark files created by Google that record geographic information data such as time, longitude, latitude, and altitude for a specific location or continuous locations) and imported into Global Mapper. The target area can also be directly output in Global Mapper.

[0109] Preferably, after the target area is created, the DEM layer can be polygonally clipped through the layer control center of Global Mapper.

[0110] Preferably, after polygon clipping is completed, you can directly use the contour line generation function of Global Mapper (line distance needs to be set).

[0111] Preferably, Gaussian projection can be performed on the target area by loading the CGCS2000 standard in Global Mapper and configuring the reference points.

[0112] Preferably, the original terrain triangulated mesh surface mentioned above, as well as the excavation and fill surfaces referred to below, are essentially terrain surfaces (DTMs). A terrain surface is a digital terrain model, a visual representation of a continuous surface in virtual space using a large number of three-dimensional spatial points. A DTM can be understood as a digital representation of terrain attribute information, which generally includes easting, northing, elevation, slope, and aspect. Establishing a terrain surface is a prerequisite for creating a BIM (Building Information Modeling) model for a project. In Civil 3D, terrain surfaces can be divided into four types: triangulated mesh surfaces, triangulated volume surfaces, grid surfaces, and grid volume surfaces. Triangulated mesh surfaces are composed of irregular triangles. When Civil 3D creates a TIN surface from 3D points, it performs a Delaunay triangulation on those points. With Delaunay triangulation, no point lies within the circle defined by the vertices of any triangle. To create the TIN lines, Civil 3D connects the closest surface points. In other words, a TIN surface is created by connecting the points in the file at their closest distances to each other, forming a series of triangles.

[0113] Preferably, the preset reservoir design parameters are determined according to the size, parameters and conditions of the pumped-storage power station to be constructed, and are also predetermined parameters. The parameters include various parameters related to the reservoir, such as: determination of dam crest elevation and width; wave-breaking wall design; dam crest elevation; dam crest width; dam slope design; dam body partitioning; reinforced concrete panel design; toe plate and connecting plate design; seams and water stops of wave-breaking walls, panels, and toe plates, etc., or dam parameters, excavation parameters, fill parameters, and main water level characteristics in Civil 3D. All the aforementioned design-related parameters should be taken into consideration, and the reservoir design in this embodiment is based on the design of the pumped-storage power station to be constructed. It is a conventional and existing design process, and this embodiment will not repeat the specific parameters of each preliminary design.

[0114] Furthermore, step S4, obtaining the optimal route of the cut surface and the fill surface, and obtaining the distance length of the optimal route and the height difference of the maximum point of the optimal route, includes:

[0115] Step S41: dividing the reservoir basin design surface model into cube grids of a preset size.

[0116] Step S42: retain the topmost cube grid and determine whether the height difference between adjacent cube grids exceeds a preset height difference threshold.

[0117] Step S43: Delete the grids that exceed the preset height difference threshold, and use the remaining cube grids as a candidate grid set.

[0118] Step S44 : defining each grid in the candidate grid set as a node, defining the cut surface as the starting point, the fill surface as the end point, and all other nodes as waypoints.

[0119] Step S45: Calculate the minimum number of grids required to reach the end point from the starting point by using the A_star algorithm.

[0120] Step S46: Obtain the grids corresponding to the minimum number of grids, and connect them in sequence to form the optimal route.

[0121] Furthermore, in step S6, the volume value of the fill part is defined as positive, the volume value of the excavation part is defined as negative, and the volume value of the fill part and the volume value of the excavation part are summed to obtain a sum value, including:

[0122] Step S61, define the horizontal projection area of each triangulated mesh of the comparison surface as .

[0123] Step S62, define the height difference between the vertical projection height of each triangulated surface and the reference surface as follows: .

[0124] Step S63 : determining the relationship between the height difference between the vertical plane projection of each triangulated mesh and the reference surface and the zero value.

[0125] Step S64: if the height difference between the vertical plane projection of the current triangulation network and the reference surface is greater than zero, it is classified as the fill part; if the height difference between the vertical plane projection of the current triangulation network and the reference surface is less than zero, it is classified as the cut part.

[0126] In step S65, the product of the horizontal projection area and the vertical projection height is obtained based on the same triangulated network, and the volume value of the same triangulated network is calculated according to formula (2):

[0127] (2).

[0128] in, For the The volume value of a triangulated network.

[0129] Step S66: Determine the relationship between the volume value of each triangulated mesh and the zero value.

[0130] Step S67: if the volume value of the current triangulated network is greater than zero, it is classified as the volume value of the fill part; if the volume value of the current triangulated network is less than zero, it is classified as the volume value of the excavation part.

[0131] Step S68: sum the volume value of the filling part and the volume value of the excavation part to obtain a sum value.

[0132] Furthermore, in step S9, the final fill volume and the final cut volume are input into the reservoir basin design surface model, and the dam axis, dam crest elevation, the reservoir basin surface, the cut surface, and the fill surface are updated through Civil 3D to obtain the determined parameters of the pumped storage reservoir area. Thereafter, the following steps are also included:

[0133] Step S10: Rendering the basin surface, the cut surface, and the fill surface using layered color gradations of different colors.

[0134] Step S20: adding a preset transparency to the model portion on the side of the dam axis away from the pumped storage reservoir area.

[0135] Step S30 , adding a preset reflectivity to the model portion of the side of the dam axis adjacent to the pumped storage reservoir area, excluding the reservoir basin surface, the cut surface, and the fill surface.

[0136] Step S40: sending the processed reservoir basin design surface model to an external visual monitoring terminal.

[0137] Preferably, the above model processing operations can be completed directly in Civil 3D.

[0138] Furthermore, step S7, iterating the sum value through a global optimization algorithm to minimize the total carbon emissions, specifically includes the following steps:
