[0042] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0043] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the present disclosure should have the common meanings understood by those skilled in the art to which the present disclosure belongs.

[0044] The following describes the technical scenarios involved in the embodiments of the present disclosure.

[0045] Considering the impact of photovoltaic storage and charging power market transactions on the carbon emission factors of both parties to the transaction and related users, a photovoltaic storage and charging carbon emission calculation method for the entire process of source, network, storage and load of the power system including power market transactions is proposed; and the characteristics and calculation methods of the electric carbon emission factors in the presence of green electricity transactions and energy storage are studied. Based on the above theory, the embodiment of the present disclosure provides a photovoltaic storage and charging carbon emission calculation method based on an electric carbon meter, and uses a photovoltaic storage and charging plus electric carbon meter system to observe the changes in current, voltage, power and other parameters between various nodes in the power grid to evaluate the stability, reliability and energy efficiency of the power grid. The photovoltaic storage and charging carbon emission calculation based on the electric carbon meter needs to comprehensively consider multiple technical issues such as data collection, determination of electric carbon factors, data processing and analysis, accuracy and reliability, real-time monitoring and feedback, etc., to ensure accurate evaluation and monitoring of the system's carbon emissions.

[0046] According to an embodiment of the present disclosure, an embodiment of a method for calculating indirect carbon emissions of a photovoltaic energy storage and charging system is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0047] In this embodiment, a method for calculating indirect carbon emissions of a photovoltaic storage and charging system is provided, which can be used in a photovoltaic storage and charging system; the photovoltaic storage and charging system includes renewable energy power generation equipment, energy storage equipment, a power grid and a user side.

[0048] For example Figure 1As shown, renewable energy power generation equipment can be understood as photovoltaic power generation equipment, energy storage equipment can be understood as energy storage battery packs, and the user side can be understood as electrical equipment, namely charging piles and V2G charging piles. Among them, each device in the light storage and charging system is connected to an electric carbon meter, which is used to detect changes in parameters such as current, voltage, and power of the equipment to measure the total amount of electric energy generated or used by the equipment. Among them, renewable energy power generation equipment includes but is not limited to photovoltaic power generation equipment, wind power generation equipment, and hydropower generation equipment.

[0049] Another example Figure 2 As shown, the solar-storage-charging system can obtain the total amount of electricity generated or used by each device through an electricity-carbon meter connected to each device, thereby helping to ensure accurate assessment and monitoring of the indirect carbon emissions of the solar-storage-charging system.

[0050] Figure 3 is a flow chart of a method for calculating indirect carbon emissions of a solar-storage-charging system according to an embodiment of the present disclosure. Figure 3 As shown, the process includes the following steps:

[0051] Step S101, determining a first indirect carbon emission of the renewable energy power generation equipment according to a first amount of electricity from the renewable energy power generation equipment used by the user side and a first electricity carbon emission factor corresponding to the renewable energy power generation equipment.

[0052] Specifically, the electricity carbon emission factor usually refers to the average carbon dioxide emissions generated per unit of electricity (usually one kilowatt-hour, or 1 kilowatt-hour) in the electricity production process. It is an important parameter for measuring the carbon footprint of electricity.

[0053] More specifically, when the renewable energy power generation equipment is a photovoltaic power generation equipment, the photovoltaic power generation equipment uses solar energy to generate electricity. The solar power generation form does not produce greenhouse gases in the process of electricity production, and emits green electricity with no attached carbon and an electric carbon emission factor of 0. After the green electricity is input into the light storage and charging system node, according to formula (1), the electric carbon emission factor of the node and other input electric energy will be apportioned, that is, under the carbon attachment assumption, there will be no electric energy with an electric carbon emission factor of 0 in the node output electric energy. As a special kind of electricity transaction, the carbon measurement of green electricity trading has a more significant impact on the electricity consumption behavior of electricity users. If the green electricity generated by the user is self-generated and self-used, its carbon emissions are:

[0054] C own =λ use_green W use_green (1)

[0055] Among them, C own represents the first indirect carbon emissions of renewable energy power generation equipment, λ use_green Represents the first carbon emission factor corresponding to renewable energy power generation equipment, Wuse_green It indicates the first amount of electricity from the renewable energy power generation equipment used by the user side.

[0056] Step S102: determining a second indirect carbon emission of the energy storage device according to a second amount of electricity from the energy storage device used by the user side and a second electric carbon emission factor corresponding to the energy storage device.

[0057] In some specific embodiments, the corresponding second indirect carbon emission calculation method can be selected according to the current use state of the energy storage device, wherein the current use state includes the power input state and the power output state. Specifically, as shown below:

[0058] When the energy storage device is in the input state, the second indirect carbon emission amount after the energy storage device inputs electric energy for the nth time can be determined according to the first emission factor after the energy storage device inputs electric energy for the nth time, the remaining electric energy before the n+1th time of electric energy input, the target electric energy for the n+1th time of input and the second emission factor, as shown in formula (2):

[0059]

[0060] in, is the second indirect carbon emission after the n+1th input of electricity, W is the first emission factor after the energy storage device inputs electric energy for the nth time; in_i is the amount of electricity input to the energy storage device for the i-th time; W out_j is the amount of electricity output by the energy storage device for the jth time; m is the total number of times the energy storage device outputs electricity up to the n+1th time when it inputs electricity; W in_n+1 The carbon emission factor of the electricity input for the energy storage device for the n+1th time is the second emission factor λ in_n+1 target power.

[0061] Among them, in the above formula (2) It can be used to indicate the remaining power of the energy storage device before the n+1th input of power.

[0062] Considering the energy storage device as a node, according to the carbon attachment assumption, the carbon attachment capacity of the electric energy in the energy storage device is the same, so the second electric carbon emission factor after the energy storage device inputs electric energy for the n+1th time is:

[0063]

[0064] In the formula,

[0065] It can be seen from the above formula (3) that the second carbon emission factor of the energy storage device can be recursively obtained through the electrical energy input each time and its associated carbon emissions.

[0066] When the energy storage device is in the state of outputting electric energy, the second indirect carbon emission after the energy storage device outputs electric energy for the m+1th time can be determined according to the second indirect carbon emission after the electric energy is input for the n+1th time, the first emission factor and the amount of electric energy output for the m+1th time, as shown in formula (4):

[0067]

[0068] in, is the second indirect carbon emission after the m+1th output of the energy storage device, is the second indirect carbon emission after the energy storage device inputs electricity for the n+1th time, W out_m+1 is the amount of electricity output by the energy storage device for the m+1th time; n+1 is the total number of times the energy storage device inputs electricity before the m+1th time of outputting electricity. According to the carbon attachment hypothesis, the carbon emission factor of the energy storage device remains unchanged after output, that is,

[0069] From the above formulas (2)-(4), it can be seen that the second indirect carbon emissions of energy storage equipment and the corresponding second electric carbon emission factor calculation only use the energy storage equipment port electric energy meter measurement value. It is worth noting that, on the one hand, energy storage equipment has a time domain carbon emission transfer effect, which transfers the attached carbon at the input time to the attached carbon at the output time; on the other hand, energy storage equipment has a long-tail effect of carbon emissions, and the attached carbon of the input electric energy will have a long-term impact on the electric carbon emission factor of the energy storage equipment.

[0070] Step S103: determining a third indirect carbon emission of the power grid according to a third amount of electricity from the power grid used by the user side and a third electricity carbon emission factor corresponding to the power grid.

[0071] In some specific embodiments, the third indirect carbon emissions of the power grid may be determined by:

[0072] Step S1031, determining a third electricity carbon emission factor of the power grid in a target time period, and determining a third amount of electricity used by the user side from the power grid in the target time period.

[0073] The target time period can be understood as any time period.

[0074] Step S1032: determining the third indirect carbon emission based on the third electrical carbon emission factor and the third electrical quantity.

[0075] The above steps S1031 and S1032 are described by taking an example:

[0076] In the power grid, if the user L and the power plant G are in [t a , t b ] The amount of electricity W exists during the time periodtrans If there is a transaction, there is a channel between user L and power plant G. G is the power plant a The cumulative power generation from time to time t; For user L a The cumulative power consumption from time to time t. For simplicity, assume that t∈[t a , t b ], the amount of electricity passing through each branch between user L and power plant G is greater than the electricity consumption of user L.

[0077] When t = t k , When, if In any period of time The third electricity carbon emission factor of user L is and third indirect carbon emissions for:

[0078]

[0079]

[0080] in: is the third carbon emission factor of power plant G during this period, represents the target time period [t x , t y ]The internal user side uses the third electricity from the power grid.

[0081] Step S104, determining the target indirect carbon emissions on the user side according to the first indirect carbon emissions, the first source ratio corresponding to the renewable energy power generation equipment, the second indirect carbon emissions, the second source ratio corresponding to the energy storage equipment, the third indirect carbon emissions, and the third source ratio corresponding to the power grid.

[0082] In some specific embodiments, the target indirect carbon emissions on the user side can be calculated by formula (7):

[0083] C user =K G λ G W G +K green λ green W green +K energy( 1-η energy ) energy W energy (7)

[0084] Among them, K G is the proportion of the third source corresponding to the power grid, K greenThe first source ratio corresponding to photovoltaic power generation equipment, K energy is the second source ratio corresponding to the energy storage device; G The third carbon emission factor for electricity supply to the grid, W G The third amount of electricity from the power grid used by the user side; green is the first electricity carbon emission factor of photovoltaic power generation equipment, W green is the first amount of electricity from the renewable energy power generation equipment used by the user side; η energy is the energy efficiency of the energy storage device, which indicates the efficiency of energy storage and release of the energy storage device, λ enegy W is the second carbon emission factor of the electric energy converted within the energy storage device, which takes into account the energy efficiency loss of the energy storage device itself and the carbon emission of the energy conversion process. energy The second amount of electricity from the energy storage device used by the user.

[0085] In some specific embodiments, the source ratio of the power grid, photovoltaic power generation equipment and energy storage equipment in the above formula (7) can be adjusted according to various factors, as follows:

[0086] The corresponding source proportions can be set according to the energy sources and types. For example, photovoltaic power generation equipment generally uses solar energy to generate electricity. Solar power generation does not produce greenhouse gases in the process of electricity production, and emits green electricity with no attached carbon and an electric carbon emission factor of 0. Photovoltaic power generation has lower carbon emissions. Therefore, the first source proportion corresponding to photovoltaic power generation equipment is relatively small. Grid power supply is generally composed of mixed energy, namely fossil energy and renewable energy. Among them, fossil energy has higher carbon emissions. Therefore, the third source proportion corresponding to the grid is relatively large.

[0087] You can set the corresponding source ratio according to the geographical location. For example, the energy market and power sources of different regions vary significantly. Some regions may rely more on renewable energy, while other regions may rely on fossil fuels. This geographical location factor will directly affect the carbon content of electricity. Therefore, regions that rely on fossil fuels have a larger proportion of third sources corresponding to their power grids; regions that rely on renewable energy have a larger proportion of first sources corresponding to their renewable energy power generation equipment.

[0088] The corresponding source ratio can also be set according to the energy consumption pattern and time distribution. For example, relying on the power grid for power supply during the peak period of energy consumption may lead to higher carbon emissions. Therefore, when the target time period belongs to the peak period of energy consumption, the proportion of the third source corresponding to the power grid is larger; conversely, when the target time period belongs to the low-peak period of energy consumption, the proportion of the third source corresponding to the power grid is smaller.

[0089] The disclosed embodiment can form a complete photovoltaic storage and charging carbon emission monitoring system by calculating the indirect carbon emissions from four aspects: renewable energy power generation equipment, energy storage equipment, power grid and user side, and realize the full-chain carbon emission monitoring and management from energy production, energy storage to final energy users. The carbon trading measurement method covers the carbon emissions of power generation, energy storage, power grid and user side, and accurately calculates and evaluates carbon trading by considering the electric energy from different sources and its carbon emission factors, as well as the impact of trading volume. Overall, these carbon trading measurement methods and frameworks provide important tools for carbon management in power systems. By quantifying and monitoring carbon emissions, not only more effective carbon reduction goals can be achieved, but also the application and market development of clean energy technologies can be promoted. These measures not only contribute to environmental protection and climate change response, but also promote economic development and social sustainability. Therefore, the measurement method of carbon trading in the power system is not only a technical consideration, but also an important part of the global energy transformation and carbon reduction strategy.
