[0020] The amount of carbon emission reduction in grid regulation is determined based on the energy storage discharge and the power generation carbon emission factor.

[0030] Based on the second power information and the regional carbon emission factor, the target network loss carbon emission is determined.

[0031] According to one embodiment of this application, the target carbon emission from network loss is determined through the following steps:

[0053] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0054] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0055] The following description, in conjunction with the accompanying drawings, details the method for determining carbon emission reduction in a source-grid-load-storage system, the carbon emission reduction determination device 300 for a source-grid-load-storage system, the electronic equipment, and the readable storage medium provided in this application, through specific embodiments and application scenarios.

[0056] The method for determining the carbon emission reduction of the source-grid-load-storage system can be applied to the terminal, and can be executed by the hardware or software in the terminal.

[0057] The carbon emission reduction determination method for a source-grid-load-storage system provided in this application embodiment can be executed by an electronic device or a functional module or entity in an electronic device that can implement the carbon emission reduction determination method for the source-grid-load-storage system. The following uses an electronic device as the execution subject to illustrate the carbon emission reduction determination method for a source-grid-load-storage system provided in this application embodiment.

[0058] like Figure 1 As shown, the method for determining the carbon emission reduction of the source-grid-load-storage system includes steps 110, 120 and 130.

[0059] Step 110: Obtain carbon emission factor information for the target power grid supply area when the source-grid-load-storage system is not connected to the target power grid supply area.

[0060] Among them, the source-grid-load-storage system is a system that integrates power generation, transmission, consumption and storage functions, and can be put into use in specific areas connected to the power grid.

[0061] The "source" in a power generation, grid, load, and storage system refers to power generation resources, which can be green energy power generation resources, such as wind power and photovoltaic power generation; the "grid" in a power generation, grid, load, and storage system refers to the power transmission and distribution network; the "load" in a power generation, grid, load, and storage system refers to the power load, that is, the power consumption end; and the "storage" in a power generation, grid, load, and storage system refers to energy storage equipment that can store electrical energy.

[0062] In this embodiment, the area where the power grid is to be connected to the source-grid-load-storage system is the target power grid supply area.

[0063] The carbon emission factor, also known as the carbon emission coefficient or carbon content, is a parameter that describes the amount of greenhouse gas emissions generated per unit of energy or activity during energy consumption or a specific activity.

[0064] In this step, when the source-grid-load-storage system is not connected to the target power grid supply area, carbon emission factor information of the target power grid supply area is obtained. The carbon emission factor information can characterize the carbon emission situation of the target power grid supply area before it is connected to the source-grid-load-storage system.

[0065] Step 120: Based on carbon emission factor information, obtain the target energy substitution carbon emission reduction and the target grid loss carbon emission reduction during the target metering period when the source-grid-load-storage system is connected to the target power grid supply area.

[0066] Among them, the target energy substitution carbon emission reduction refers to the amount of carbon emissions reduced in the target power grid supply area when the power generation of the source-grid-load-storage system is used to generate electricity during the target metering period after the source-grid-load-storage system is connected to the target power grid supply area.

[0067] Understandably, the larger the target carbon emission reduction, the greater the carbon emission reduction in the region when the source-grid-load-storage system is connected to the target power grid.

[0068] In this embodiment, the target grid loss carbon emission reduction refers to the change in carbon emissions in the target grid power supply area due to changes in grid transmission losses during the target metering period after the source-grid-load-storage system is connected to the target grid power supply area.

[0069] It should be noted that the target grid loss carbon emission reduction can measure the fluctuation of carbon emissions corresponding to the change in grid loss in the target grid supply area after the source-grid-load-storage system is connected to the target grid supply area. It can be a positive or negative value, depending on the impact of the source-grid-load-storage system on grid loss.

[0070] For example, if the target carbon emission reduction due to grid loss is positive, it means that grid loss is reduced and carbon emissions in the target grid supply area are reduced; if the target carbon emission reduction due to grid loss is negative, it means that grid loss is increased and carbon emissions in the target grid supply area are increased.

[0071] The target measurement period is a pre-set measurement period of a certain length, such as 1 day, 1 week, or 2 weeks.

[0072] Understandably, by pre-setting a metering period of a certain duration and calculating the target carbon emission reduction through energy substitution and the target carbon emission reduction through grid loss within that period, the carbon emission reduction situation of the source-grid-load-storage system connected to the target power grid can be quantitatively assessed.

[0073] For example, from January to June of a certain year, during this period, the target carbon emission reduction of the source-grid-load-storage system within 6 months is approximately atCO2e, and the target carbon emission reduction of the source-grid-load-storage system within 6 months is approximately btCO2e.

[0074] In this step, after the source-grid-load-storage system is connected to the target power grid supply area, during the target metering period, based on the carbon emission factor information of the target power grid supply area and the relevant power data after the source-grid-load-storage system is connected to the target power grid supply area, the target energy substitution carbon emission reduction and the target grid loss carbon emission reduction can be calculated.

[0075] Step 130: Based on the target carbon emission reduction through energy substitution and the target carbon emission reduction through grid loss, determine the target carbon emission reduction of the source-grid-load-storage system within the target metering period.

[0076] The target carbon emission reduction can be the total amount of carbon emissions reduced in the target power grid supply area during the target metering period, provided that the source-grid-load-storage system is connected to the target power grid supply area.

[0077] In practice, the target carbon emission reduction includes the target energy substitution carbon emission reduction and the target grid loss carbon emission reduction within the target metering period. The larger the target carbon emission reduction, the greater the total reduction in carbon emissions in the target power grid supply area.

[0078] In this embodiment, the target carbon emission reduction of the source-grid-load-storage system during the target metering period can be determined by summing the target carbon emission reduction from energy substitution and the target carbon emission reduction from grid loss during the target metering period.

[0079] For example, if the target carbon emission reduction for the source-grid-load-storage system is ctCO2e and the target carbon emission reduction for grid loss is dtCO2e over a one-year period, then the target carbon emission reduction for the source-grid-load-storage system is (c+d)tCO2e.

[0080] In this embodiment, based on the carbon emission factor information when the source-grid-load-storage system is not connected to the target power grid supply area, the target energy substitution carbon emission reduction and the target grid loss carbon emission reduction are obtained within the same target metering period after the source-grid-load-storage system is connected to the target power grid supply area. The two aspects of energy substitution and grid loss are comprehensively evaluated, the target carbon emission reduction of the source-grid-load-storage system within the target metering period is accurately calculated, and the carbon emission reduction value of the source-grid-load-storage system is quantified.

[0081] According to the carbon emission reduction determination method of the source-grid-load-storage system provided in the embodiments of this application, by obtaining the target energy substitution carbon emission reduction corresponding to energy substitution after the source-grid-load-storage system is connected to the target power grid supply area, and the target grid loss carbon emission reduction corresponding to the power loss of the power grid after the source-grid-load-storage system is connected to the target power grid supply area, the carbon emission reduction of the source-grid-load-storage system connected to the target power grid supply area can be accurately evaluated from the two aspects of energy substitution and grid loss, and the carbon emission reduction value of the source-grid-load-storage system can be quantified.

[0082] In some embodiments, carbon emission factor information includes regional carbon emission factor and power generation carbon emission factor for the target power grid supply area, and target energy substitution carbon emission reduction includes green energy carbon emission reduction and grid regulation carbon emission reduction of the source-grid-load-storage system. Green energy carbon emission reduction is determined based on regional carbon emission factor, and grid regulation carbon emission reduction is determined based on power generation carbon emission factor.

[0083] It is understandable that the means of reducing carbon emissions through energy substitution in the source-grid-load-storage system can include generating electricity with green energy, or using energy storage devices to store energy for time shifting and power support to regulate the power supply to the grid.

[0084] Among them, green energy carbon emission reduction refers to the amount of carbon dioxide emissions reduced by the source-grid-load-storage system by replacing traditional energy power generation with green energy power generation during the target metering period.

[0085] Grid regulation carbon emission reduction refers to the amount of carbon dioxide emissions reduced by the source-grid-load-storage system during the target metering period by using energy storage devices to shift energy over time and support power to stabilize the grid, thus replacing traditional power generation facilities.

[0086] In this embodiment, the regional carbon emission factor characterizes the carbon emissions of the original power production and consumption process in the target power grid supply area before the source-grid-load-storage system is connected to the target power grid supply area.

[0087] In practice, by using regional carbon emission factors, the amount of electricity generated by green energy and the amount of carbon dioxide emitted by non-green energy, the carbon emission reduction of the source-grid-load-storage system by using green energy to replace traditional energy can be accurately calculated, and the carbon emission reduction of green energy during the target metering period can be determined.

[0088] In this embodiment, the power generation carbon emission factor characterizes the amount of carbon dioxide emissions generated per unit of electricity generated by traditional power generation facilities in the target power grid supply area when the source-grid-load-storage system has not yet been connected to the target power grid supply area.

[0089] Traditional power generation facilities refer to facilities that use coal, oil, natural gas or other fossil fuels as fuel to generate electricity, such as thermal power plants.

[0090] It should be noted that by replacing traditional power generation with energy storage discharge during peak periods and frequency regulation by supercapacitors in the source-grid-load-storage system, the carbon emission reduction of the energy storage time shift and power support of the source-grid-load-storage system can be accurately assessed based on the carbon emission factor of power generation and the amount of electricity released by the energy storage equipment.

[0091] In practice, the target carbon emission reduction can be calculated using the following formula:

[0092] C 替代 =C 源 +C 储

[0093] Among them, C 替代 C represents the target carbon emission reduction through energy substitution during the target measurement period. 源 C represents the carbon emission reduction from green energy during the target measurement period. 储 The amount of carbon emission reduction from grid regulation during the target metering period.

[0094] For example, if the green energy carbon emission reduction of the source-grid-load-storage system is ftCO2e and the grid regulation carbon emission reduction of the source-grid-load-storage system is gtCO2e within a one-year period in the target grid supply area, then the target energy substitution carbon emission reduction of the source-grid-load-storage system is (f+g)tCO2e.

[0095] In this embodiment of the application, by determining the carbon emission reduction of replacing traditional energy generation with green energy, and the carbon emission reduction of the power grid by power support and power support of energy storage devices, the target energy substitution carbon emission reduction within the target metering period is calculated, which can accurately reflect the carbon emission reduction value of the source-grid-load-storage system by replacing traditional energy generation with green energy.

[0096] In some embodiments, the carbon emission reduction from green energy is determined through the following steps:

[0097] To obtain the green energy generation, grid-load-storage system's electricity purchases from the grid, and non-green energy carbon emissions during the target metering period, assuming the source-grid-load-storage system is connected to the target power grid supply area.

[0098] The carbon emission reduction amount of green energy is determined based on regional carbon emission factors, green energy power generation, grid purchases of electricity and carbon emissions from non-green energy.

[0099] Among them, green energy power generation is the sum of power generation from green energy sources such as wind power and photovoltaic power in the source-grid-load-storage system during the target metering period; grid purchase power refers to the amount of electricity purchased by the source-grid-load-storage system from the grid during the target metering period; and non-green energy carbon emissions are the cumulative carbon emissions of non-green energy in the source-grid-load-storage system during the target metering period.

[0100] In this embodiment, the carbon emission reduction from green energy is the amount of carbon emissions reduced by green energy replacing traditional energy generation in the source-grid-load-storage system during the target metering period.

[0101] In practice, for the source-grid-load-storage system, the carbon emission reduction of green energy can be determined by calculation based on the regional carbon emission factor of the target grid supply area and the green energy power generation, grid purchase volume and non-green energy carbon emissions during the target metering period.

[0102] In some embodiments, the carbon emission reduction from green energy is determined based on regional carbon emission factors, green energy power generation, grid-purchased electricity, and carbon emissions from non-green energy sources, including:

[0103] The first electricity difference is determined based on green energy generation and grid purchase volume.

[0104] The carbon emissions of the first green energy source are determined based on the first electricity difference and the regional carbon emission factor.

[0105] The carbon emission reduction amount of green energy is determined based on the carbon emissions of primary green energy and non-green energy.

[0106] The first power difference is the difference between the green energy generation of the source-grid-load-storage system and the power purchased by the grid during the target metering period.

[0107] It should be noted that the first power difference represents the net power generation generated through green energy in the source-grid-load-storage system.

[0108] In this embodiment, based on the first power difference and the regional carbon emission factor, the first green energy carbon emission amount, which characterizes the carbon emission situation of green energy power generation, can be obtained. Combining the first green energy carbon emission amount and the non-green energy carbon emission amount, the green energy carbon emission reduction amount, which characterizes the replacement of traditional energy power generation with green energy, can be calculated.

[0109] In practice, the first green energy carbon emission can be obtained by multiplying the first electricity difference by the regional carbon emission factor, and the green energy carbon emission reduction can be obtained by subtracting the first green energy carbon emission from the non-green energy carbon emission.

[0110] In this embodiment, the carbon emission reduction from green energy refers to the actual carbon emission reduction achieved by replacing traditional energy with green energy in the source-grid-load-storage system during the target metering period, after deducting the carbon emissions from non-green energy.

[0111] It should be noted that the source-grid-load-storage system can use green energy, but it may also involve the use of some non-green energy. Deducting these emissions from the total emission reduction can reflect the true carbon emission reduction effect.

[0112] In this embodiment, the carbon emissions of non-green energy in the source-grid-load-storage system can be determined by multiplying the power generation of non-green energy and the carbon emission factor of non-green energy during the target metering period. The carbon emission factor of non-green energy characterizes the amount of carbon dioxide emitted by non-green energy per unit of electricity generated during the power generation process.

[0113] It is understandable that the carbon emissions corresponding to purchasing electricity from the grid can be obtained by multiplying the amount of electricity purchased from the grid by the regional carbon emission factor.

[0114] In practice, the carbon emission reduction from green energy can be calculated using the following formula:

[0115] C 源 =(Q 项目绿 -Q 项目购 )*EF EL -C 项目非绿

[0116] Among them, Q 项目绿Q represents the green energy generation of the power generation system (source, grid, load, and storage) within the target metering period. 项目购 For the power purchases by the power generation, grid, load, and storage system during the target metering period, EF EL The regional carbon emission factor for the target power grid supply area, while C 项目非绿 C represents the carbon emissions of non-green energy in the source-grid-load-storage system during the target metering period. 源 The carbon emission reduction of green energy in the source-grid-load-storage system during the target measurement period.

[0117] For example, after a power generation, grid, load, and storage system is connected to a certain power grid area, the green energy power generation Q will increase within one month. 项目绿 The amount of electricity purchased from the grid is wMWh, Q. 项目购 The regional carbon emission factor EF for the target grid-supply area is nMWh. EL The cumulative carbon emissions (C) from non-green energy sources within two months are calculated as ktCO2e / MWh. 项目非绿 If it is stCO2e, then according to the calculation formula C 源 =(Q 项目绿 -Q 项目购 )*EF EL -C 项目非绿 Receive 1 month of green energy carbon emission reduction C 源 It is (kw-kn-s)tCO2e.

[0118] In this embodiment, when determining the carbon emission reduction of green energy power generation in the source-grid-load-storage system, the carbon emissions of non-green energy in the source-grid-load-storage system and the electricity purchased by the grid are calculated comprehensively to accurately assess the real carbon emission reduction caused by green energy replacing traditional energy during the target metering period.

[0119] In some embodiments, the carbon emission reduction from grid regulation is determined through the following steps:

[0120] The amount of energy stored in the grid-load-storage system during the target metering period is obtained when the grid-load-storage system is connected to the target power grid supply area.

[0121] Based on the energy storage discharge and the carbon emission factor of power generation, the carbon emission reduction of grid regulation is determined.

[0122] It should be noted that during peak electricity demand periods or when the power grid is unstable in the target grid supply area, the source-grid-load-storage system can store or release electrical energy through the synergistic effect of energy storage equipment in time shifting and power support, thereby replacing traditional power generation facilities for balancing and reducing carbon emissions.

[0123] In this embodiment, the carbon emission reduction caused by the energy storage discharge and the power generation carbon emission factor can be accurately calculated when releasing electrical energy, i.e., the carbon emission reduction caused by grid regulation.

[0124] It should be noted that the carbon emission factor of power generation in the target power grid supply area can be obtained before the source-grid-load-storage system is connected to the target power grid supply area. This value can be derived based on the past operation and coal consumption data of traditional power generation facilities.

[0125] In practice, the carbon emission reduction from grid regulation can be determined using the following formula:

[0126] C 储 =Q 储放 *EF 火

[0127] Among them, Q 储放 EF represents the energy discharge of the energy storage system within the target metering period. 火 C represents the carbon emission factor of power generation in the target grid supply area. 储 This refers to the carbon emission reduction of the power grid regulation system during the target metering period for the source-grid-load-storage system.

[0128] For example, after a power grid area is connected to a source-grid-load-storage system, the energy storage discharge amount Q within one month... 储放 The carbon emission factor EF of power generation in the target grid supply area is pMWh. 火 If the value is qtCO2e / MWh, then according to the calculation formula C 储 =Q 储放 *EF 火

[0129] The carbon emission reduction C from grid regulation over one month can be obtained. 储 It is (pq)tCO2e.

[0130] In this embodiment of the application, when calculating the carbon emission reduction of green energy, the carbon emissions corresponding to the purchase of electricity from the grid by the source-grid-load-storage system (including the purchase of electricity by energy storage devices) are deducted. When calculating the carbon emission reduction of grid regulation, it is not necessary to repeatedly calculate the carbon emissions of the energy storage electricity purchase part, which can effectively improve the efficiency and accuracy of carbon emission reduction calculation.

[0131] In some embodiments, the carbon emission factor information includes the regional carbon emission factor of the target power grid supply area, and the target grid loss carbon emission reduction is determined through the following steps:

[0132] Based on the regional carbon emission factor, the first grid loss carbon emission of the target power grid supply area during the target metering period is obtained when the source-grid-load-storage system is not connected to the target power grid supply area.

[0133] Based on the regional carbon emission factor, the target grid loss carbon emission amount of the target power grid supply area is obtained during the target metering period when the source-grid-load-storage system is connected to the target power grid supply area.

[0134] The target carbon emission reduction amount is determined based on the first network loss carbon emission amount and the target network loss carbon emission amount.

[0135] Among them, grid loss carbon emissions refer to the amount of carbon dioxide emitted from the electricity generated by the power transmission loss of a certain power grid area over a period of time, representing the carbon emissions generated by the power grid area due to power loss.

[0136] In this embodiment, the first grid loss carbon emission refers to the grid loss carbon emission corresponding to the target power grid supply area during the target metering period, when the source-grid-load-storage system is not connected to the target power grid supply area.

[0137] The target grid loss carbon emissions refer to the amount of grid loss carbon emissions corresponding to the target grid supply area during the target metering period, when the source-grid-load-storage system is connected to the target grid supply area.

[0138] In this embodiment, by using the first grid loss carbon emission before the grid-load-storage system is connected, and the target grid loss carbon emission during the same metering period after the grid-load-storage system is connected, the change in carbon emissions corresponding to the change in grid losses in the target power supply area after the grid-load-storage system is connected can be calculated. This change is the target grid loss carbon emission reduction.

[0139] In practice, the target carbon emission reduction C due to network loss can be determined using the following formula. 损减 :

[0140] C 损减 =BE NL -PE NL

[0141] Among them, BE NL The carbon emissions from the first grid loss during the target metering period before the source-grid-load-storage system is connected to the target power grid supply area; PE NL C represents the target grid loss carbon emissions during the target metering period after the source-grid-load-storage system is connected to the target power grid supply area; 损减 The target carbon emission reduction for grid loss in the target power grid supply area during the target metering period.

[0142] For example, before a source-grid-load-storage system is connected to a target power grid supply area, the carbon emissions (BE) of the first grid loss in that target power grid supply area within one month are as follows: NL For AtCO2e, after connecting the source-grid-load-storage system to the target grid supply area, the target grid loss carbon emissions PE within one month. NL If it is BtCO2e, then according to formula C 损减 =BE NL -PE NL The target network loss carbon emission reduction C for the target area within one month was obtained. 损减It is (AB)tCO2e.

[0143] It is understandable that if AB is greater than 0, it means that after the source-grid-load-storage system is connected to the target power grid supply area, the grid loss is reduced; if AB is less than 0, it means that after the source-grid-load-storage system is connected to the target power grid supply area, the grid loss is increased.

[0144] In this embodiment of the application, when assessing the carbon emission reduction of the source-grid-load-storage system connected to the target power grid supply area, the target energy substitution carbon emission reduction is calculated while the carbon emission reduction corresponding to the power loss of the power grid is comprehensively assessed to determine the target grid loss carbon emission reduction, thus comprehensively evaluating the carbon emission reduction after the source-grid-load-storage system is connected to the target power grid supply area.

[0145] In some embodiments, the first network loss carbon emissions are determined by the following steps:

[0146] Obtain the first power information of transmission and transformation equipment within the target power grid supply area when the source-grid-load-storage system is not connected to the target power grid supply area;

[0147] Based on the first power information and the regional carbon emission factor, the first network loss carbon emission is determined.

[0148] It should be noted that power transmission and transformation equipment refers to equipment used for power transmission and voltage conversion in power systems. For example, power transmission and transformation equipment can be lines and main transformers that are directly connected to the grid connection point.

[0149] In this embodiment, the first power information may include the power value, voltage value, internal resistance value, etc. of the lines and transformers directly connected to the grid connection point in the target power grid supply area during the target metering period before the source-grid-load-storage system is connected to the grid.

[0150] In practice, the carbon emissions from the first grid loss before the source-grid-load-storage system is connected to the target power grid supply area can be calculated using the following formula:

[0151]

[0152] Among them, for the i-th transmission and transformation equipment among m transmission and transformation equipment in the power grid supply area of ​​the target power grid, in the j-th target metering period, P ij * Q* represents the active power of the power transmission and transformation equipment. ij V* represents the reactive power of the power transmission and transformation equipment. ij R is the voltage of the power transmission and transformation equipment. i The resistance of the power transmission and transformation equipment; EF EL BE is the regional carbon emission factor for the target power grid supply area. NL The first grid loss carbon emissions in the target power grid supply area.

[0153] It should be noted that T is the recording period, which can be divided into multiple target metering periods. ΔT is the length of each target metering period. For example, if T is 1 day and ΔT is 1 hour, then the first power information of the power transmission and transformation equipment can be collected within 24 target metering periods.

[0154] In this embodiment, obtaining the first grid loss carbon emission amount through the first power information and the regional carbon emission factor can help determine the target grid loss carbon emission reduction amount and assess the change in carbon emissions after the source-grid-load-storage system is connected to the target power grid supply area.

[0155] In some embodiments, the target carbon emissions from network loss are determined through the following steps:

[0156] Acquire the second power information of the transmission and transformation equipment within the target power grid supply area when the source-grid-load-storage system is connected to the target power grid supply area;

[0157] Based on the second power information and the regional carbon emission factor, the target network loss carbon emission is determined.

[0158] In this embodiment, the second power information may include the power value, voltage value, internal resistance value, etc. of the lines and transformers directly connected to the grid connection point in the target power grid supply area during the target metering period after the source-grid-load-storage system is connected to the grid.

[0159] In practice, the target grid loss carbon emissions after the source-grid-load-storage system is connected to the target power grid supply area can be calculated using the following formula:

[0160]

[0161] Specifically, for the i-th transmission and transformation equipment among m transmission and transformation equipment in the power grid supply area of ​​the target power grid, during the j-th target metering period of the accounting period T, P ij Q represents the active power of the power transmission and transformation equipment. ij V represents the reactive power of the power transmission and transformation equipment. ij R is the voltage of the power transmission and transformation equipment. i The resistance of the power transmission and transformation equipment; EF EL The regional carbon emission factor for the area supplied by the target power grid.

[0162] In this embodiment, the target grid loss carbon emissions are obtained through the second power information and the regional carbon emission factor, which can help determine the target grid loss carbon emission reduction and assess the change in carbon emissions after the source-grid-load-storage system is connected to the target grid power supply area.

[0163] It should be noted that after the power source-grid-load-storage system is connected to the target power grid supply area, if the power information of the transmission and transformation equipment is difficult to obtain, only the carbon emissions generated by the losses of the transmission and transformation equipment such as transformers at the grid connection point can be considered.

[0164] In some embodiments, the target carbon emissions from network loss are determined through the following steps:

[0165] When the source-grid-load-storage system is connected to the target power grid supply area, obtain the third power information of the grid-connected equipment in the target power grid supply area;

[0166] Based on third-party power information and regional carbon emission factors, the target network loss carbon emission amount is determined.

[0167] The grid connection point is the location where the source-grid-load-storage system connects to the power grid within the target power grid supply area. The grid connection point equipment may include the main transformer, etc.

[0168] Understandably, the third power information refers to the power, voltage, and internal resistance values ​​of the grid-connected equipment during the target metering period after the source-grid-load-storage system is connected to the target power grid supply area.

[0169] In this embodiment, after the source-grid-load-storage system is connected to the target power grid supply area, when the power information of the transmission and transformation equipment is difficult to obtain, the loss of the transformer in the grid connection point equipment can be considered to determine the target grid loss carbon emissions.

[0170] In practice, the target network loss carbon emissions generated by the transformer can be calculated using the following formula:

[0171]

[0172] Among them, transformer a is the grid connection point equipment. After the source-grid-load-storage system is connected to the target power grid supply area, P aj Let Q be the active power of transformer a during the j-th target metering period. aj Let V be the active power of transformer a during the j-th target metering period. aj R is the voltage of transformer a. a Let be the resistance of transformer a.

[0173] It should be noted that the active and reactive power of transformer a can be calculated using the following formula:

[0174] P aj +jQ aj =P aj * +jQ aj * +L ij

[0175] Before the power generation, grid-load-storage system is connected to the target power grid supply area, the active power of transformer a during the j-th target metering period is P. aj *The reactive power of transformer a during the j-th target metering period is Q. aj * L ij Let be the power of grid-connected tie line i in the power transmission and transformation equipment during the j-th target metering period.

[0176] In some embodiments, the carbon emission factor information includes the regional carbon emission factor for the target grid supply area, which is determined through the following steps:

[0177] To obtain the regional power generation, regional power inflow, and regional power generation carbon emissions of the target power grid supply area when the source-grid-load-storage system is not connected to the target power grid supply area;

[0178] The regional carbon emission factor is determined based on regional power generation, regional inflow of electricity, and regional carbon emissions from power generation.

[0179] The regional power generation of the target power grid supply area refers to the total power generation of the power generation facilities in the target power grid supply area during the target metering period before the source-grid-load-storage system is connected to the target power grid supply area.

[0180] The regional inflow of electricity to the target power grid supply area refers to the total amount of electricity flowing into the target power grid supply area from other power grid areas during the target metering period before the source-grid-load-storage system is connected to the target power grid supply area.

[0181] In this embodiment, the regional carbon emissions from power generation in the target grid supply area refer to the total carbon dioxide emissions generated during power generation and power inflow / outflow in the area before the source-grid-load-storage system is connected to the target grid supply area during the target metering period.

[0182] In practice, the regional carbon emission factor of the target power grid supply area can be determined using the following formula:

[0183] EF EL =C 区域b / (Q 区发b +Q 区流b )

[0184] Among them, for the target measurement period, C 区域b Q represents the carbon emissions from power generation in the target grid supply area. 区发b Q represents the regional power generation in the target power grid supply area. 区流b EF is the regional inflow of electricity to the target power grid supply area. EL The regional carbon emission factor for the area supplied by the target power grid.

[0185] For example, given two adjacent power grid regions, A and B, over a period of one year, the carbon emissions from power generation in region A (the target power grid supply area) will be C. 区域bFor mtCO2e, the amount of electricity Q flowing from grid region B into the target grid supply region A is... 区流b Let Q be the regional power generation of the target grid supply area A, which is nMWh. 区发b Given x MWh, the regional carbon emission factor of the target power grid supply area A can be obtained as [m / (n+x)]tCO2e / MWh.

[0186] In this embodiment, after the source-grid-load-storage system is connected to the target power grid supply area, the carbon emission factor information of the target power grid supply area is determined by the regional carbon emission factor and the power generation carbon emission factor of the target power grid supply area. This allows us to obtain the green energy carbon emission reduction and the target grid loss carbon emission reduction in the target energy substitution carbon emission reduction, which helps to quantify the carbon emission reduction in the target power grid supply area after the source-grid-load-storage system is put into operation.

[0187] The following is a specific example.

[0188] like Figure 2 As shown, the source-grid-load-storage system is intended to be connected to the target power grid supply area. Before the source-grid-load-storage system is connected to the target power grid supply area, information such as regional power generation, regional inflow of electricity, regional power generation carbon emissions, power value, voltage value, internal resistance value, and power generation carbon emission factor of the power transmission and transformation equipment in the target power grid supply area is obtained. After the source-grid-load-storage system is connected to the target power grid supply area, information such as green energy power generation, power grid purchase, non-green energy carbon emissions, and changes in power value and voltage value of the power transmission and transformation equipment in the source-grid-load-storage system in the target power grid supply area is obtained.

[0189] In this embodiment, the regional carbon emission factor of the target grid supply area before connecting to the source-grid-load-storage system is calculated based on the regional power generation, regional inflow power, and regional power generation carbon emissions. Based on the regional carbon emission factor and the power generation carbon emission factor, the carbon emission reduction of green energy and the carbon emission reduction of grid regulation are calculated, and the target energy substitution carbon emission reduction corresponding to the energy substitution of the target grid supply area of ​​the source-grid-load-storage system is determined.

[0190] Based on the regional carbon emission factor, and according to the power information of the transmission and transformation equipment before the source-grid-load-storage system is connected to the target power grid supply area, and the power information of the transmission and transformation equipment after the source-grid-load-storage system is connected to the target power grid supply area, the target grid loss carbon emission reduction corresponding to the grid loss of the source-grid-load-storage system connected to the target power grid supply area is determined.

[0191] In practice, the overall carbon emission reduction of the source-grid-load-storage system is assessed. The sum of the target energy substitution carbon emission reduction and the target grid loss carbon emission reduction is taken as the total target carbon emission reduction generated by the source-grid-load-storage system when connected to the target power grid supply area. This quantifies the carbon emission reduction value that the source-grid-load-storage system can bring during the target metering period.

[0192] In this embodiment, by obtaining the target carbon emission reduction corresponding to energy substitution after the source-grid-load-storage system is connected to the target power grid supply area, and the target carbon emission reduction corresponding to the power grid loss after the source-grid-load-storage system is connected to the target power grid supply area, the carbon emission reduction of the source-grid-load-storage system connected to the target power grid supply area can be accurately evaluated from the perspectives of energy substitution and power grid loss, thus quantifying the carbon emission reduction value of the source-grid-load-storage system.

This application embodiment uses the execution of the carbon emission reduction determination method for a source-grid-load-storage system by the carbon emission reduction determination device 300 as an example to illustrate the carbon emission reduction determination device 300 for a source-grid-load-storage system provided in this application embodiment.

[0194] This application also provides a carbon emission reduction determination device 300 for a source-grid-load-storage system.

[0198] The second processing module 330 is used to determine the target carbon emission reduction of the source-grid-load-storage system within the target metering period based on the target energy substitution carbon emission reduction and the target grid loss carbon emission reduction.

[0199] According to the carbon emission reduction determination device 300 of the source-grid-load-storage system provided in the embodiments of this application, by obtaining the target energy substitution carbon emission reduction corresponding to the energy substitution after the source-grid-load-storage system is connected to the target power grid supply area, and the target grid loss carbon emission reduction corresponding to the power loss of the power grid after the source-grid-load-storage system is connected to the target power grid supply area, the carbon emission reduction of the source-grid-load-storage system connected to the target power grid supply area can be accurately evaluated from the two aspects of energy substitution and grid loss, and the carbon emission reduction value of the source-grid-load-storage system can be quantified.
