[0002] With the change of global climate, the requirement for reducing carbon emissions is higher and higher. In order to improve the effect of reducing carbon emissions, it is necessary to analyze carbon emissions.

[0068] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0069] It should be noted that the terms "first", "second", etc. used in the present application can be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from the second element. The terms "include" and "have" used in the present application and any variations thereof are intended to cover non-exclusive inclusion. The term "a plurality of" used in the present application means two and more than two. The term "and / or" used in the present application means one of the options or any combination of multiple options.

[0070] In an embodiment, as shown in Figure 1 A user-side electricity carbon emission responsibility accounting method based on a power grid supply-demand relationship is provided, and the present embodiment takes the method applied to a terminal as an example. It should be understood that the method can also be applied to a server, and can also be applied to a system including a terminal and a server, and can be realized through the interaction of the terminal and the server. In the present embodiment, the method includes the following steps:

[0071] In step 102, the power supply power information, the operating state of each energy type of the power supply side, and the user electricity consumption information of the user side in the current period are obtained.

[0072] In an embodiment of the present application, in order to accurately collect the required data, the terminal can obtain the power supply power information corresponding to each energy type on the power supply side through the power dispatching system. For example, the power dispatching system records the output active power, interconnection line power and other information of various power sources (including thermal power, wind power, photovoltaic power, energy storage, etc.); the user side electricity consumption data can be obtained through the power marketing system. For example, the user's power consumption, electricity consumption and other information can be obtained from the power marketing system.

[0073] The sensors corresponding to each energy type on the power supply side are connected to the terminal, and the terminal collects data according to a preset period. For example, the data collection period can be 15 minutes. For the current period, the terminal obtains the active power of each type of power supply in the power grid at the current moment through the sensor. , rated capacity ( ) and tie line power ( ), where i represents different power types, including thermal power (th), wind power (w), photovoltaic (pv), energy storage (s), etc. Represents the present moment.

[0074] The power consumption of the user side in this sampling period is E T ( ).

[0075] The operating status of energy storage devices can be categorized as charging, discharging, or idle, depending on the energy type. The terminal uses the power dispatch system to determine the operating status of the energy storage device. For example, the power dispatch system monitors the energy storage device in real time, and the terminal can directly obtain the corresponding operating status of each energy storage device from the power dispatch system.

[0076] For thermal power energy, the terminal can calculate the load rate of the thermal power unit To determine the operating status of thermal power energy, the terminal can determine the real-time load rate of the thermal power unit according to the following formula (1):

[0077] (1)

[0078] Step 104 : Determine the initial carbon emission responsibility transfer index corresponding to each energy type based on the operating status corresponding to each energy type.

[0079] In the embodiment of the present application, the initial carbon emission responsibility transfer index represents the carbon emission responsibility that different power types should bear for each kilowatt-hour of electricity produced or transmitted under a specific operating state. It is used to reflect the contribution of various power sources to carbon emissions in the process of electricity production and supply, and quantify the division of responsibilities of different energy types at the carbon emission level.

[0080] For thermal power units, the initial carbon emission responsibility transfer index comprehensively considers the relative output of the unit, and has different performances under different load rates, reflecting the influence of the operating state of the thermal power unit on the carbon emission responsibility, and can reflect the difference in the carbon emission responsibility of the user side and the power side under different working conditions. The initial carbon emission responsibility transfer index of zero-carbon power sources such as wind power and photovoltaic power is related to the user-side carbon responsibility factor at the current time of the power grid and the power generation capacity of the power source, reflecting its contribution to the transfer of user-side carbon emission responsibility under different load periods. The initial carbon emission responsibility transfer index of centralized energy storage facilities is determined according to the charging and discharging state, reflecting the carbon emission responsibility of the power source under different operating modes. The initial carbon emission responsibility transfer index of the tie line is based on the power flow direction, reflecting the carbon emission responsibility of the power transmission between different power grids. Further, the initial carbon emission responsibility transfer index is used to quantify the carbon emission responsibility of various power sources in the power grid.

[0081] The terminal preliminarily determines the carbon emission degree corresponding to each energy type according to the operating state of different energy types, and further determines the initial carbon emission responsibility transfer index corresponding to each energy type by taking the carbon emission degree as the basis for analysis. For the emission responsibility of different energy types, different carbon emission responsibility calculation strategies are pre-set in the terminal for accurately identifying the carbon emission responsibility of peak shaving power sources such as thermal power in low-load operation or standby state, and realizing the accurate allocation of carbon emission responsibility to electricity users in the future load peak period, rather than attributing it to the current electricity users, so as to improve the accuracy of carbon emission responsibility allocation for each energy type.

[0082] Step 106, determining the user-side carbon responsibility factor corresponding to the current period based on the initial carbon emission responsibility transfer index and the power source power information.

[0083] Among them, the user-side carbon responsibility factor represents the carbon emission responsibility that the user side of the power grid should bear for using one degree of electricity in the current period.

[0084] In the embodiments of the present application, the terminal determines the user-side carbon responsibility factor corresponding to the current period based on the initial carbon emission responsibility transfer index and the power source power information. The user-side carbon responsibility factor can clearly define the responsibility share of the power source side and the user side for carbon emission in the process of power grid operation, and realize the reasonable allocation of power supply and demand relationship on the source-load side.

[0085] The terminal determines the user-side carbon responsibility factor corresponding to the current period through analysis of the initial carbon emission responsibility transfer index and power supply power information. Specifically, in the operation of the power system, there are differences in load conditions between peak and valley, and the operation state and carbon emission responsibility of different stages of thermal power generating units are also different. When the power load is at a valley, the thermal power generating unit as a peak regulation cannot be completely shut down, but can only be adjusted to the lowest load operating condition, the purpose of which is to ensure that it can quickly climb when the load increases again to meet the electricity demand. Even at this time, the power generation of clean energy such as wind and light is large, but the power grid may have to give up using clean energy such as wind and light in order to maintain the operation of the thermal power generating unit at the minimum power. This minimum power operation is not for meeting the electricity demand of the power terminal at the moment, but for the rotating reserve required for power grid regulation. Therefore, the carbon emissions generated by the thermal power generating unit during the fire suppression period should not be borne by the electricity consumer at that time, but should be shared by the electricity consumer in the future during the load peak period. At the load peak, the carbon emission responsibility borne by the electricity side is no longer only the direct carbon emission of the power supply side at that time, but also the direct carbon emission of the low-load operation of the peak-regulating power supply during the valley period. Therefore, the terminal realizes the quantification of the carbon emission responsibility of each energy type through the initial carbon emission responsibility transfer index determined based on the operation state of each energy type, and further calculates the user-side carbon responsibility factor of the overall carbon emission at the current moment in the current period according to the initial carbon emission responsibility transfer index. The user-side carbon responsibility factor can be quantified by the responsibility attribution ratio. Finally, the terminal obtains the user-side carbon responsibility factor, which can improve the accuracy and rationality of the carbon emission responsibility division of the user-side carbon responsibility factor.

[0086] In step 108, the user-side carbon emission responsibility data is determined according to the user-side carbon responsibility factor and the user electricity consumption information.

[0087] In the embodiment of the present application, the terminal calculates the user-side carbon emission responsibility data of the user side within a certain period of time according to the user-side carbon responsibility factor and the user information, as the quantification result of the current carbon emission responsibility of the user side. In a specific embodiment, the terminal can calculate the user-side carbon emission responsibility data according to a preset period (for example, the preset period is 15 minutes), and feed back the user-side carbon emission responsibility data to the user side, so as to encourage the user side to participate in the power system regulation and promote the source-load coordination interaction.

[0088] In the above-mentioned user-side electricity consumption carbon emission responsibility accounting method based on the power grid supply and demand relationship, the initial carbon emission responsibility transfer index corresponding to each energy type is determined by dynamically collecting the power and operating status of each energy type on the power supply side and the user-side demand information. Based on the operating status of each energy type, flexible adjustment of carbon emission responsibility during peak load periods can be achieved, and the influencing factors that can be reflected in carbon emission responsibility can be increased, so that the user side not only bears the carbon emission responsibility for direct electricity consumption, but also bears the indirect carbon emissions generated by system regulation needs during off-peak periods, avoiding the "invalid carbon emissions" generated on the power supply side due to peak-shaving needs during off-peak periods from being incorrectly allocated, thereby improving the accuracy of user carbon responsibility allocation.

[0089] In an exemplary embodiment, different energy types have different ways of determining the initial carbon emission responsibility transfer index based on the operating status, such as Figure 2 As shown, step 104 includes steps 202 to 204. Among them:

[0090] Step 202 : Determine a carbon emission responsibility calculation strategy transferred to the user side based on the operating status of the energy type.

[0091] Among them, the carbon emission responsibility calculation strategy includes the energy carbon responsibility transfer coefficient corresponding to each energy type.

[0092] In the embodiment of the present application, since different energy types have their own unique operating characteristics, which significantly affect their carbon emissions, the terminal determines the carbon emission responsibility calculation strategy based on the operating status of the energy type.

[0093] For thermal power generation, the operating status of the corresponding thermal power units is closely related to the load factor. During the initial low-load phase, the pattern of carbon emission responsibility changes differently than during high-load phases. For example, during low-load operation, such as during reduced-load operation, thermal power units primarily maintain hot standby, so the attribution and calculation of carbon emission responsibility differ from that during normal full-load operation. When thermal power units are operating at high loads, nearing full load, the user bears a higher carbon emission responsibility. Therefore, the terminal determines the energy carbon responsibility transfer coefficient for thermal power generation based on the relative output of the thermal power units.

[0094] For zero-carbon power sources such as wind power and photovoltaic power, the carbon emission responsibility per kilowatt-hour transferred to the user side is equal to the user-side carbon responsibility factor of the power grid at that time. The product of their power generation. The operating status of zero-carbon power sources like wind power and photovoltaic power is significantly affected by natural conditions. During peak load periods, when user demand for electricity is high, these zero-carbon power sources shift more carbon emissions; during low load periods, the carbon emissions shift less. Therefore, their carbon emission responsibility calculation strategy must consider factors such as grid load conditions and their own power generation.

[0095] The centralized energy storage facility has two operating states of charging and discharging. The terminal determines the energy storage responsibility coefficient corresponding to the centralized energy storage facility according to the charging state and the discharging state of the centralized energy storage facility, and then determines the carbon emission responsibility calculation strategy according to the energy storage responsibility coefficient of the centralized energy storage facility. For the carbon emission responsibility calculation strategy of the tie line, since the operating state of the tie line includes the power receiving state and the power sending state, the terminal respectively adopts the carbon emission responsibility factor of different power grids to determine the carbon emission responsibility calculation strategy.

[0096] Therefore, the terminal first determines the operating state of each energy type, and further determines the energy carbon responsibility transfer coefficient (for example, the energy carbon responsibility transfer coefficient and the energy storage responsibility coefficient corresponding to the thermal power energy) of each energy type according to the operating state, and constructs the carbon emission responsibility calculation strategy based on the energy carbon responsibility transfer coefficient.

[0097] In step 204, each energy type is calculated according to the energy carbon responsibility transfer coefficient to obtain the initial carbon emission responsibility transfer index corresponding to each energy type.

[0098] In the embodiment of the application, the terminal calculates each energy type according to the energy carbon responsibility transfer coefficient, thereby obtaining the initial carbon emission responsibility transfer index corresponding to each energy type, so as to quantify the carbon emission responsibility of different energy types in the process of power production and supply.

[0099] In the embodiment, by dividing the carbon emission responsibility calculation strategy of the energy type in different operating states, the energy carbon responsibility transfer coefficient corresponding to each energy type in the current period is determined as the basis for the initial carbon emission responsibility transfer index of each energy type, which reasonably quantifies the carbon emission responsibility of each energy type in the process of power production and supply, provides a basis for subsequent power grid carbon emission analysis and carbon emission responsibility allocation, and improves the accuracy of user-side carbon emission responsibility allocation.

[0100] In one exemplary embodiment, the energy type also includes an energy storage device, and the energy carbon responsibility transfer coefficient (i.e., the energy storage responsibility coefficient) corresponding to the energy storage device is the energy storage load rate; step 204 includes step 2041. Wherein:

[0101] In step 2041, for the energy storage device, if the operating state of the energy storage device is the discharging state, the initial carbon emission responsibility transfer index corresponding to the energy storage device is determined based on the energy storage load rate corresponding to the energy storage device and the preset average carbon emission factor of the power grid.

[0102] In the embodiment of the application, for the calculation of the energy carbon responsibility transfer coefficient of the energy storage device, the terminal first determines the operating state of the energy storage device at the current time according to the power dispatching system. The operating state of the energy storage device includes the discharging state and the charging state. When the terminal obtains the power supply information of the energy storage device through the power dispatching system For When the terminal determines that the operating state of the energy storage device is the charging state, at this time, the role of the energy storage device is as a common power consumption terminal and does not provide power to the user side. Since the user side does not use the power energy of the energy storage device, it is indicated that the user side does not need to bear the carbon emission responsibility for the carbon emission of the energy type of the energy storage device at the current time.

[0103] Therefore, the terminal only considers the power supply power information When the operating state of the energy storage device is the discharging state, the energy storage device is considered as a factor in the calculation of the carbon emission responsibility of the user side.

[0104] For the initial carbon emission responsibility transfer index calculation of the energy storage device in the discharging state, the terminal takes the preset average carbon emission factor of the power grid as the energy storage responsibility coefficient, and calculates the initial carbon emission responsibility transfer index according to the energy storage load rate and the preset average carbon emission factor of the power grid, and finally obtains the initial carbon emission responsibility transfer index corresponding to the energy storage device. The initial carbon emission responsibility transfer index corresponding to the energy storage device is calculated according to the following formula (2):

[0105] (2)

[0106] Wherein, is the energy storage load rate, is the preset average carbon emission factor of the power grid, which can be the national average carbon emission factor.

[0107] In this embodiment, the operating state is distinguished by the power supply power information. When in the charging state, it is determined that the user side does not need to bear the carbon emission responsibility of the energy type of the energy storage device, and the unreasonable allocation of responsibility is avoided. Only when the energy storage device is in the discharging state, it is considered in the calculation range of the carbon emission responsibility of the user side. For the energy storage device in the discharging state, the preset average carbon emission factor of the power grid is taken as the energy storage responsibility coefficient, and the initial carbon emission responsibility transfer index is calculated in combination with the energy storage load rate, so as to ensure that the calculation result is consistent with the actual operation, and the accuracy of the user carbon responsibility allocation is improved in the carbon emission responsibility calculation of the energy storage device.

[0108] In an exemplary embodiment, the energy type includes thermal power energy. For the calculation of the initial carbon emission responsibility transfer index of the thermal power energy, as shown in Figure 3 , step 104 includes steps 302 to 306. Wherein:

[0109] Step 302, obtaining a preset thermal power carbon emission factor.

[0110] ​In an embodiment of the present application, the preset thermal power carbon emission factor includes thermal power carbon emission factors corresponding to thermal power units of different fuel types. For example, the thermal power carbon emission factor corresponding to a gas-fired thermal power unit is 0.4 kgCO2 / kWh, and the thermal power carbon emission factor corresponding to a coal-fired thermal power unit is 0.8 kgCO2 / kWh.

[0111] The preset thermal power carbon emission factor can be pre-set in the terminal, or it can be queried in real time on the official platform to obtain the preset thermal power carbon emission factor.

[0112] Step 304 : determining the energy carbon responsibility transfer coefficient corresponding to the thermal power energy based on the load status, technical output limit, and maximum responsibility coefficient of the thermal power energy in the current cycle.

[0113] In an embodiment of the present application, the terminal determines the energy carbon responsibility transfer coefficient corresponding to the thermal power energy based on the load state, technical output limit and maximum responsibility coefficient of the thermal power energy. The load state of the thermal power energy reflects the operating load of the thermal power unit within a certain period. The load state is the load rate sequence within the first statistical time window (for example, the last 30 days); the technical output limit can reflect the difference between the technical minimum load rate and the maximum load rate of the thermal power unit; the maximum responsibility coefficient is determined by the carbon balance inverse method. Specifically, the terminal determines the energy carbon responsibility transfer coefficient corresponding to the thermal power energy based on the relative output of the thermal power unit. The correlation between the energy carbon responsibility transfer coefficient corresponding to the thermal power energy and the relative output of the thermal power unit can be expressed by the Logistic (Logistic regression) function model shown in the following formula (3):

[0114] (3)

[0115] Among them, such as Figure 4 As shown, the parameters is the center point of the Logistic function curve, parameter is the growth rate of the Logistic function curve, parameter Represents the upper limit of the Logistic function curve, that is, the energy carbon responsibility transfer coefficient corresponding to thermal power energy The maximum value that can be achieved. Determined by the load rate median tracking method, the terminal uses the median of the load state as a parameter , in order to achieve adaptive update of the center point with seasonal load migration; parameter The adjustable interval method of the unit is used to calculate the minimum and maximum technical load rates (i.e. technical output limits) of the thermal power unit, and automatically recalculate after the unit is overhauled or technically modified to achieve parameter adjustment. Update of; parameters Through the carbon balance reverse calculation method, with a quarterly update cycle and a rolling year as the second statistical time window, the actual carbon emissions of thermal power units E year =ΣP th ( )·C 0,th ·Δ By using the balance principle (i.e. the total carbon emission responsibility of the user side is equal to the total direct carbon emission of the power supply side), the total responsibility of the user side for the whole year is equal to the actual carbon emission E year To ensure long-term carbon balance.

[0116] Energy carbon responsibility transfer coefficient corresponding to thermal power energy Relative output of thermal power units The relationship between Figure 4 It can be seen that at the load rate N th In the initial stage, the energy carbon responsibility transfer coefficient corresponding to thermal power energy is relatively low. Relative output of thermal power units exponential growth; at the median of the stable operating load factor N th _med, the growth rate reaches its peak; then the growth rate gradually slows down until the maximum operating load rate. Then, after the terminal obtains the correlation between the energy carbon responsibility transfer coefficient corresponding to thermal power energy and the relative output of thermal power units through the load rate median tracking method, the unit adjustable interval method and the carbon balance reverse method, the user-side carbon emission responsibility of thermal power energy can be divided according to this correlation: when the relative output of the thermal power unit is determined Afterwards, based on Calculate with the Logistic function model to obtain the energy carbon responsibility transfer coefficient corresponding to thermal power energy At the same time, when the relative output of thermal power units The larger the value, the higher the carbon emission responsibility of the user side; when the relative output of thermal power units The smaller it is, the lower the carbon emission responsibility on the user side.

[0117] Step 306 : determining an initial carbon emission responsibility transfer index for thermal power energy based on the energy carbon responsibility transfer coefficient corresponding to the thermal power energy and a preset thermal power carbon emission factor.

[0118] In the embodiment of the present application, the terminal determines the initial carbon emission responsibility transfer index of thermal power energy according to the energy carbon responsibility transfer coefficient corresponding to thermal power energy and the preset thermal power carbon emission factor. The carbon emission responsibility per kilowatt-hour of thermal power units is the product of the energy carbon responsibility transfer coefficient corresponding to thermal power energy and its carbon emission factor, that is, the initial carbon emission responsibility transfer index of thermal power energy is obtained by multiplying the energy carbon responsibility transfer coefficient corresponding to thermal power energy and the preset thermal power carbon emission factor. The initial carbon emission responsibility index of thermal power energy is The calculation of is shown in the following formula (4):

[0119]

[0120] in, is the carbon emission factor corresponding to the thermal power unit.

[0121] When the thermal power unit is in different operating states, its carbon emission responsibility is also different. When the thermal power unit is in low load operation (such as the fire suppression state) to maintain hot standby, r th ( ) = 0, the carbon emission responsibility is mainly borne by the power supply side; as the unit output N th Increase, r th ( ) gradually increases. When the unit is close to full load operation, r th ( ) reaches its maximum value, at which point the user side bears a higher carbon emission responsibility.

[0122] In this embodiment, the energy carbon responsibility transfer coefficient corresponding to the thermal power energy is determined by the load state, technical output limit and maximum responsibility coefficient of the thermal power energy, which can increase the operating characteristics of the thermal power unit as an influencing factor that can reflect the carbon emission responsibility, and the correlation between the energy carbon responsibility transfer coefficient corresponding to the thermal power energy and the relative output situation of the thermal power unit is adaptively updated, which can dynamically reflect the operating changes of the thermal power unit; the initial carbon emission responsibility transfer index is determined according to the energy carbon responsibility transfer coefficient corresponding to the thermal power energy and the preset thermal power carbon emission factor, which can clarify the carbon emission responsibility of the user side under different operating conditions of the thermal power unit, thereby improving the accuracy of user carbon responsibility allocation.

[0123] In an exemplary embodiment, the energy type also includes a tie line, and the calculation of the initial carbon emission responsibility transfer index of the tie line is as follows: Figure 5 As shown, step 104 includes steps 502 to 504. Among them:

[0124] Step 502 : For the tie line, if the tie line is in a power receiving state, the user-side carbon responsibility factor corresponding to the tie line grid of the tie line is used as the initial carbon emission responsibility transfer indicator corresponding to the tie line.

[0125] In the embodiment of the present application, when the tie line is in the received power state, it indicates that power is input into the local power grid from other power grids corresponding to the tie line through the tie line. Therefore, the terminal takes the user-side carbon responsibility factor of the tie line power grid as the initial carbon emission responsibility transfer index of the local power grid, which can accurately reflect the attribution of the received power in terms of carbon emission responsibility. The user-side carbon responsibility factor of the tie line power grid can be calculated by the same method as steps 102 to 108.

[0126] Further, the terminal takes the user-side carbon responsibility factor corresponding to the tie line power grid as the initial carbon emission responsibility transfer index corresponding to the tie line, and takes the carbon emission responsibility calculation strategy corresponding to the tie line. Finally, the external power grid energy structure and carbon emission are fully considered when accounting for carbon emission responsibility, and the carbon emission responsibility distribution is more reasonable.

[0127] In step 504, if the tie line is in the sent power state, the user-side carbon responsibility factor of the local power grid in the current period of the tie line is taken as the initial carbon emission responsibility transfer index corresponding to the tie line.

[0128] In the embodiment of the present application, when the tie line is in the sent power state, it indicates that power is transmitted from the local power grid corresponding to the tie line. Therefore, the terminal takes the user-side carbon responsibility factor of the local power grid in the current period of the tie line as the initial carbon emission responsibility transfer index corresponding to the tie line in the current period, and reflects the carbon emission responsibility accounting strategy of the local power grid through the user-side carbon responsibility factor of the local power grid in the current period of the tie line.

[0129] In the embodiment, the determination mode of the initial carbon emission responsibility transfer index is determined by the running state of the tie line, which realizes the quantification of the carbon emission responsibility of the tie line in power production and supply, realizes the reasonable allocation of the user-side and power-side carbon emission responsibility, and can improve the accuracy of the user-side carbon emission responsibility allocation.

[0130] In one exemplary embodiment, step 106 includes step 1061. In step 1061:

[0131] In step 1061, the power supply power information corresponding to each energy type is weighted and summed based on the initial carbon emission responsibility transfer index to obtain the user-side carbon responsibility factor corresponding to the current period.

[0132] In the embodiment of the present application, in the current period, after the terminal completes the calculation of the initial carbon emission responsibility transfer index corresponding to each energy type, the terminal calculates the power supply power information corresponding to each energy type by weighted summation according to the carbon emission responsibility of the user side in each energy type reflected by the initial carbon emission responsibility transfer index, obtains the carbon emission responsibility contribution of each energy type in the current period, and obtains the user-side carbon responsibility factor corresponding to the current period. The user-side carbon responsibility factor The calculation is shown in the following formula (5):

[0133] (5)

[0134] wherein, represents the time point, represents the power information of each energy type at the current time point, represents the initial carbon emission responsibility transfer index corresponding to each energy type, represents different power types, including thermal power (th), wind power (w), photovoltaic power (pv), energy storage (s), and tie line (l).

[0135] Specifically, the greater the power of the energy type, the more power is generated by the energy type in the current period, and the greater the carbon emission responsibility generated according to the initial carbon emission responsibility transfer index. Then, the terminal adds up the carbon emission contributions of all energy types and performs weighted summation calculation through the initial carbon emission responsibility index, and the terminal obtains the user-side carbon responsibility factor of all energy types in the current period, which comprehensively considers the power generation of different energy types in the current period and the carbon emission responsibility per kilowatt-hour of each energy type.

[0136] In this embodiment, the initial carbon emission responsibility index is used to determine the user-side carbon responsibility factor of all energy types, which can accurately reflect the dynamic change of the overall carbon emission responsibility of the power grid in the current period, and improve the accuracy of the user-side carbon emission responsibility accounting.

[0137] In one exemplary embodiment, step 108 includes step 1081. Wherein:

[0138] Step 1081, according to the user electricity consumption information and the responsibility attribution ratio, the total user-side carbon emission responsibility is divided, and the user-side carbon emission responsibility data is obtained.

[0139] In the embodiment of the application, the terminal calculates the total user-side carbon emission responsibility according to the user electricity consumption information of the current period of the user side and the user-side carbon responsibility factor of the period of the power grid characterized by the responsibility attribution, and obtains the user-side carbon emission responsibility data. The calculation of the user-side carbon emission responsibility data is shown in the following formula (6):

[0140] (6)

[0141] wherein, is the user-side carbon responsibility factor, is the user electricity consumption information of the user side.

[0142] In this embodiment, the carbon emission responsibility of the user is calculated every (15min), fully considering the dynamic change of the user's electricity consumption behavior in the whole time period, so as to accurately calculate the total carbon emission responsibility of the user side, reasonably allocate the carbon emission responsibility to each related responsible subject, and finally obtain detailed and accurate carbon emission responsibility data of the user side, so that the adjustment behavior of the power supply side and the user side is coordinated with each other, thereby improving the overall adjustment ability and operation efficiency of the power system.

[0143] In one specific embodiment, as shown in Figure 6 , an example of a user-side electricity carbon emission responsibility accounting method based on power supply and demand relationship is provided, including:

[0144] Step S601, data collection:

[0145] Step 6011, real-time acquisition of power generation power of various types of generator sets (including thermal power, wind power, photovoltaic power and other renewable energy sources), energy storage units such as pumped storage, and tie-line power and other data.

[0146] Step 6012, real-time collection of user-side electricity consumption information.

[0147] Step S602, calculation of carbon responsibility factor of power user side :

[0148] Step 6021, according to the real-time operation state of various types of units, determine the initial carbon emission responsibility index transferred to the user side.

[0149] Step 6022, calculate the carbon responsibility factor of the power user side , taking the weighted average value of the initial carbon emission responsibility index of various power sources and its power generation power as the carbon responsibility factor of the power user side .

[0150] Step S603, carbon emission responsibility data of user side :

[0151] Step 6031, according to the product of the carbon responsibility factor of the power user side and the user-side user electricity consumption information , the discrete time summation is obtained to obtain the carbon emission responsibility data of the user side in a period of time .

[0152] In one specific embodiment, as shown in Figure 7 ​As shown, the terminal collects power generation data of thermal power, photovoltaic power, wind power, hydropower, nuclear power, pumped storage, energy storage and tie line respectively, wherein the photovoltaic power, wind power, hydropower, nuclear power and pumped storage are zero-carbon power sources, and the pumped storage and energy storage are centralized energy storage facilities. For the initial carbon emission responsibility transfer index, the initial carbon emission responsibility transfer index of the thermal power unit is related to the unit load rate; the initial carbon emission responsibility transfer index of the zero-carbon power source is the user-side carbon responsibility factor of the power grid where the zero-carbon power source is located, because the zero-carbon power source does not generate carbon emissions; and the initial carbon emission responsibility indexes corresponding to the centralized energy storage facilities and the tie line are determined through the operating states corresponding to the centralized energy storage facilities and the tie line. Finally, the terminal obtains the user-side carbon responsibility factor by weightedly averaging the power generation of each unit.
