[0050] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0051] The power dispatch control method based on primary and secondary carbon emission quota dispatch provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or it can be placed on the cloud or other network servers. The data storage system can store the basic data of the power dispatching system and the carbon emission rights dispatching system. Among them, the terminal 102 can be but is not limited to various personal computers, laptops, smart phones, tablets, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server 104 can be implemented with an independent server or a server cluster consisting of multiple servers.

[0052] In one embodiment, Figure 2As shown, a power dispatch control method based on primary and secondary carbon emission quota dispatch is provided. This method adopts the simulation analysis method of carbon emission right dispatch for electricity-carbon coupling, simulates and solves the carbon quota price corresponding to the thermal power unit, and then combines the carbon quota price of the thermal power unit to call the security constraint model to obtain the clearing result of the thermal power unit, so as to realize the simulation of the power dispatch clearing results of each thermal power unit under the influence of different carbon quota prices, and support the research and analysis of the impact of carbon quota price on power dispatch clearing. This method is applied to Figure 1 The server in the example is used to illustrate the following steps:

[0053] Step 202, obtaining the carbon quota price corresponding to each unit carbon emission of the thermal power unit, and obtaining the unit emission carbon quota price of the thermal power unit.

[0054] Among them, thermal power units refer to devices that use fossil fuels such as coal, oil, and gas to burn to generate high-temperature and high-pressure steam to drive turbine generators to generate electricity. They belong to the power generation side of the power dispatching system.

[0055] In the power system, thermal power units are the main source of carbon emissions. Considering the carbon emission rights dispatch mechanism under the carbon emission rights dispatch environment, by establishing a carbon emission dispatch model, simulating the operation of the power system under the carbon dispatch environment, the power system regulation is considered from the perspective of low carbon, environmental protection and economy, thereby promoting energy conservation and emission reduction and improving the energy structure.

[0056] The carbon emission rights scheduling system allocates carbon emission rights to each carbon emission entity and determines the carbon emission price. The carbon emission price includes the carbon quota price, the emission reduction equipment operation price and the carbon emission reduction investment price. For example:

[0057] Cost 碳排放 =Cost 碳配额 +Cost 减排设备运营代价 +Cost 碳减排投资代价 ;

[0058] Among them, Cost 碳排放 Cost represents the cost of carbon emissions. 碳配额 Indicates the carbon quota cost, Cost 减排设备运营代价 Cost represents the operating cost of emission reduction equipment. 碳减排投资代价 Represents the investment cost of carbon emission reduction.

[0059] When simulating the carbon emission rights scheduling system, the embodiment of the present application assumes that the emission reduction equipment operating cost and carbon emission reduction investment cost corresponding to the thermal power units are fixed values, mainly simulating carbon quota scheduling and carbon quota cost.

[0060] Through simulation of the carbon emission rights scheduling system, the carbon quota price corresponding to each unit of carbon emissions of the thermal power unit is obtained, that is, the unit emission carbon quota price of the thermal power unit.

[0061] Step 204, determining the carbon quota price corresponding to the unit output of the thermal power unit according to the power generation carbon emission factor and the unit carbon emission quota price, and obtaining the unit output carbon quota price of the thermal power unit.

[0062] Among them, the carbon emission factor of power generation refers to the carbon emissions corresponding to the unit output of thermal power units.

[0063] Exemplarily, the carbon emission factor of power generation and the unit carbon emission quota price are combined to obtain the carbon quota price corresponding to the unit output of the thermal power unit, that is, the unit output carbon quota price of the thermal power unit.

[0064] Step 206, according to the safety constraint model in the power dispatching system, obtain the unit power generation plan when the total system cost is the smallest, and control each thermal power unit according to the unit power generation plan, wherein the total system cost is determined according to the unit output carbon quota cost of each thermal power unit.

[0065] Among them, the security constraint model includes the security constrained unit commitment model (Security Constrained Unit Commitment, SCUC) and the security constrained economic dispatch model (Security Constrained Economic Dispatch, SCED).

[0066] In the power dispatching system, the minimum total system cost is usually taken as the goal to obtain the unit clearing situation. In addition to considering the power generation cost of the thermal power unit, the embodiment of the present application determines the carbon quota cost of the thermal power unit through the simulation of the carbon emission dispatching system, and incorporates the carbon quota cost into the total cost of the thermal power unit.

[0067] The total system cost of the embodiment of the present application may also include the carbon emission cost of each thermal power unit, wherein, assuming that the emission reduction equipment operation cost and the carbon emission reduction investment cost corresponding to the thermal power unit are fixed values, the carbon emission cost of each thermal power unit can be expressed by the following formula:

[0068] Cost 碳配额 =∑C i，t P i，t ;

[0069] Among them, C i，t P represents the carbon quota cost per unit output of unit i in time period t, i，t Represents the output of unit i in time period t.

[0070] In addition, the power generation cost of thermal power units includes capacity cost and electricity cost. The capacity cost includes equipment depreciation cost, financial cost and management cost, while the electricity cost includes fuel cost and other variable costs including operation and maintenance.

[0071] In the above-mentioned power dispatching control method based on the first-level and second-level carbon emission quota dispatching, the carbon quota price corresponding to each unit carbon emission of the thermal power unit is obtained to obtain the unit emission carbon quota price of the thermal power unit. According to the power generation carbon emission factor and the unit carbon emission quota price, the carbon quota price corresponding to the unit output of the thermal power unit is determined to obtain the unit output carbon quota price of the thermal power unit. According to the safety constraint model in the power dispatching system, the unit power generation plan when the total system cost is the smallest is obtained, and each thermal power unit is controlled according to the unit power generation plan, wherein the total system cost is determined according to the unit output carbon quota price of each thermal power unit. The embodiment of the present application is aimed at electricity-carbon coupling, and adopts a simulation and analysis method of carbon emission rights dispatching to obtain the carbon quota price of the thermal power unit, and then combines the carbon quota price of the thermal power unit to call the safety constraint model to clear and obtain the clearing result of the thermal power unit. It can realize the simulation of the power dispatching and clearing results of each thermal power unit under the influence of different carbon quota prices, support the research and analysis of the impact of carbon quota price on power dispatching and clearing, realize the coupling optimization between the carbon emission dispatching system and the power dispatching system, and save energy consumption and resource waste.

[0072] In one embodiment, a power dispatch control method for primary and secondary carbon emission quota scheduling is provided. The method is applied to a power dispatch control system based on primary and secondary carbon emission quota scheduling, such as Figure 3 As shown, the power dispatching and control system based on the primary and secondary carbon emission rights quota scheduling will be introduced in detail below. The power dispatching and control system based on the primary and secondary carbon emission rights quota scheduling includes a data management module, an environmental configuration module, a carbon emission scheduling model module, a carbon emission scheduling simulation module and a power dispatching module.

[0073] The data management module is used to obtain and store the basic data of carbon emission scheduling simulation, and supports the rapid extraction and call of the basic data in the environment configuration module and the carbon emission scheduling model module. The data management module has built-in data editing and data import functions, and supports standardized data structure templates.

[0074] Among them, the data management module can obtain the basic data required for the long-term simulation of carbon emission scheduling. Since the existing carbon emission scheduling simulation is usually only for short-term simulation, and the compliance period of carbon emission scheduling is usually based on years, the carbon emission scheduling simulation under short-term lacks the urgency of compliance and the volatility of carbon emission costs under long-term consideration, and often obtains simulation results that are very different from the actual carbon emission scheduling.

[0075] Exemplarily, the basic data for carbon emission scheduling simulation includes data such as information of each entity, secondary carbon emission quota scheduling agreement, primary carbon scheduling quotation, secondary carbon scheduling quotation and entity carbon quota.

[0076] The environment configuration module is used to determine the subjects participating in the carbon emission rights scheduling and store the basic information of the subjects participating in the scheduling.

[0077] Among them, the environmental configuration module has built-in information models of eight typical industry entities that have been clearly included in the scope of carbon emission rights scheduling, including: power generation, petrochemicals, chemicals, building materials, steel, non-ferrous metals, papermaking and civil aviation. In this module, you can enter the name of the energy-consuming enterprise, the industry it belongs to, the region it is located in, and last year's carbon emissions. The specific model library table is as follows. This module stores the basic information of all entities participating in the carbon emission rights scheduling, clarifies the industry information, regional information and the latest annual carbon emission data of the subject, and in the subsequent initial carbon quota allocation process, performs the corresponding initial carbon quota allocation calculation based on the industry information and historical emission information of the subject.

[0078] Table 1 Main information model library table of environment configuration module

[0079]

[0080] The carbon emission scheduling model module is used to model the primary and secondary carbon emission rights scheduling scenarios in the carbon emission rights scheduling. The module has two submodules: the preset primary carbon emission scheduling model and the preset secondary carbon emission scheduling model. The scheduling of carbon emission rights and the determination of carbon quota costs are completed through the preset primary carbon emission scheduling model and the preset secondary carbon emission scheduling model.

[0081] In one implementation, the first-level carbon emission scheduling model submodule is based on the built-in scheduling process of the first-level carbon emission rights scheduling. For the auction-style scheduling of the first-level carbon emission rights scheduling, it sets parameter configuration items such as the number of scheduling starts, start time nodes, total auction quotas, auction rules, price settlement rules, single bidding quantity limit, and reported price increase and decrease limit.

[0082] Exemplarily, the primary carbon emission scheduling model submodule can have two auction rules and two price settlement rules built in. The auction rules support the selection of two modes: English auction and Dutch auction. The price settlement rules support the selection of two modes: unified price settlement and differential price settlement. Based on the actual simulation research needs, up to 4 scheduling rules can be combined, and up to 4 primary carbon emission scheduling models can be pre-built to conduct research and analysis on simulation results under different scheduling rules. The specific combinations are shown in Table 2 below. At the same time, the module reserves an expansion interface to support the subsequent on-demand expansion of auction rules and price settlement rules.

[0083] Table 2. First-level carbon emission scheduling model under different scheduling rules

[0084] Auction rules / price settlement rules Unified price settlement Differential cost settlement English Auction 1 2 Dutch Auction 3 4

[0085] The following is a brief description of the auction rules:

[0086] English auctions and Dutch auctions use different clearing methods when settling auctions. In English auctions, the minimum auction price P is set. b and the auction price step length Δp. At the end of the auction declaration, the declared quotas and declared prices of all scheduling participants are obtained. Then, based on the lowest auction price, the auction scheduling clearing quota is obtained and compared with the overall scheduling auction volume Q′. When the clearing quota volume Q1 is greater than Q′, the auction price is increased by the unit price step length to obtain the new auction price P. b +Δp, and then clear the quota Q2 again and compare it with the total auction volume again. Until a certain auction price P b +n*Δp Clearing quota amount Q n+1 Less than or equal to Q′, at this time, reversely look for the equilibrium clearing point cost P′ so that the clearing quota quantity is equal to the total auction quantity.

[0087] The Dutch auction process is opposite to the English auction in that the auction price changes in the opposite direction. c and the auction price step length Δp. At the end of the auction declaration, the declared quotas and declared prices of all scheduling participants are obtained. Then, based on the highest starting price, the auction scheduling clearing quota is obtained and compared with the overall scheduling auction volume Q′. When the clearing quota volume Q1 is less than Q′, the auction price is increased by the unit price step length to obtain the new auction price P. c -Δp, and then clear the quota Q2 again and compare it with the total auction volume again. Until a certain auction price P c -n*Δp under the clearing quota amount Q n+1 Greater than or equal to Q′, at this time, reversely find the equilibrium clearing point cost P′ so that the clearing quota quantity is equal to the total auction quantity.

[0088] The following is a brief description of the consideration settlement rules:

[0089] Under the unified price settlement model, all carbon emission rights scheduling participants will settle uniformly based on the final equilibrium clearing point price P′, which has nothing to do with their own declared prices. Under this model, all entities will quote based on their actual acceptable maximum price, thereby improving the overall social welfare benefits of carbon emission rights scheduling.

[0090] Under the differential price settlement model, all dispatching entities that ultimately win the bid in the carbon emission rights scheduling and clearing will settle according to their own declared prices. Under this model, dispatching entities with larger quota demands may increase their price declaration by a certain percentage in order to increase their own probability of winning the bid.

[0091] In one implementation, the secondary carbon emission scheduling model submodule is based on the built-in scheduling process of the secondary carbon emission rights scheduling. Since the secondary carbon emission rights scheduling includes a variety of different scheduling carbon quota definitions, but the secondary carbon emission rights scheduling quotas of carbon emission rights scheduling in different provinces have different names but similar specific rules, they can be generally classified into three categories: bidding scheduling, agreement transfer and one-way bidding. Therefore, this submodule constructs models for the three types of scheduling quotas respectively, and supports free selection of the types of scheduling quotas that need to be included in the secondary carbon emission scheduling model.

[0092] For example, the bidding resource transfer product is a typical continuous bidding resource transfer product, which can make continuous quantity and price declarations during the opening period of the secondary carbon emission rights scheduling, and conduct real-time matching and clearing for the quota asset transfer declaration data of different entities. Its model includes input items such as scheduling time (including the morning and afternoon time ranges), scheduling starting opening price, maximum holding limit and declared price increase and decrease limit.

[0093] For example, the agreement transfer product can also be understood as a large-order resource transfer product, which is defined as a large-quantity quota resource transfer contract agreed upon between the two parties. Its model includes resource transfer time, minimum resource transfer quantity, and price increase and decrease limit (the price benchmark of this indicator is taken from the previous day's closing price of the secondary carbon emission rights scheduling).

[0094] For example, a one-way bidding is an application for a large number of quota resource transfer initiated by a subject, which is similar to the auction process of the first-level carbon emission rights scheduling. Since this category generates very few resource transfers in the actual carbon emission rights scheduling operation, it is mostly a means of supplementing quotas to entities with difficulties in fulfilling carbon quotas, so this category is not modeled separately here. After checking this category, a one-way bidding configuration module will be added to the subsequent simulation module to support the entry of one-way bidding transaction contracts.

[0095] The carbon emission scheduling simulation module is used to construct simulation engineering plans with different simulation time ranges based on the scheduling declaration data and carbon quota data stored in the data management, combined with the constructed environmental configuration plan, the preset first-level carbon emission scheduling model and the preset second-level carbon emission scheduling model.

[0096] In one implementation, the carbon emission scheduling simulation module has built-in boundary configuration, which includes carbon quota configuration module, scheduling subject configuration module and one-way bidding configuration module (this module is automatically generated based on the check configuration of one-way bidding categories in the secondary carbon emission scheduling model submodule in the carbon emission scheduling model module). When all submodules are configured, clearing simulation can be performed in the simulation calculation module, and matching clearing can be used to obtain the full amount of simulation clearing results within the simulation project time range.

[0097] For example, the carbon quota configuration module has two built-in quota automatic generation and custom modes. In the quota automatic generation mode, the total amount of carbon quota free allocation Q input by the user is received. total , and then call the quota allocation model based on the historical carbon emission intensity benchmark to calculate and solve the total amount of free carbon quotas to each entity. The following formula can be used:

[0098]

[0099]

[0100] Among them, Q total,k , Q total,k,i are the carbon quota allocations for the k-th industry and the i-th entity in the k-th industry, respectively. k,i ,Emission k are the historical carbon emissions of the k-th industry and the i-th entity in the k-th industry last year, respectively, and Emission k,i The data is taken from the B_EmissionLastYear field stored in the database table of the environment configuration module of the corresponding subject.

[0101] The custom mode allows you to freely edit, add, or import the boundary data of the total amount of carbon quotas held within the simulation time range by subject.

[0102] Exemplarily, in the scheduling entity configuration module, for all scheduling entities covered in the simulation project, whether they participate in the primary carbon emission rights scheduling and the secondary carbon emission rights scheduling information is configured. This configuration information will affect the reportable entity information displayed in the subsequent simulation calculation link.

[0103] For example, the one-way bidding module is generated based on the configuration of the secondary carbon emission scheduling model submodule. When the one-way bidding category is turned on, the one-way bidding module is automatically generated, and the one-way bidding contract information can be entered in this module as the boundary of the subsequent specific simulation. The specific input information includes the transferee, transferee, transaction price, transaction quota and transaction time of the resource transfer.

[0104] In one implementation, the carbon emission scheduling simulation module has built-in simulation calculations. In the simulation calculations, the subject's daily reported quota resource transfer amount (transfer-in and transfer-out are entered separately) and reported quota resource transfer cost within the opening time range of the first-level carbon emission rights scheduling and the second-level carbon emission rights scheduling are called. The simulation calculation is divided into two layers: the first-level carbon emission rights scheduling simulation and the second-level carbon emission rights scheduling simulation. The simulation results of the first-level carbon emission rights scheduling will be supplemented to the subject's quota holding boundary formed by the carbon quota configuration, and then participate in the simulation of the second-level carbon emission rights scheduling.

[0105] Exemplarily, for the first-level carbon emission rights scheduling submodule, based on the parameters such as the scheduling start times, start time nodes, and total auction quota set in the preset first-level carbon emission scheduling model submodule, n rounds of resource transfer declarations are made respectively. The first-level carbon emission rights scheduling mode is an open auction mode, which receives the declared quota quantity and declared price of each scheduling entity.

[0106] Then, the system will automatically match and clear the results of all open sessions according to the auction rules and price settlement rules configured in the submodule of the first-level carbon emission scheduling model, and confirm the quota amount Q obtained by each scheduling entity in the first-level carbon emission rights scheduling. bid , and then the output result will be used as one of the boundaries to participate in the secondary carbon emission rights scheduling simulation.

[0107] Exemplarily, in the secondary carbon emission rights scheduling, the amount of transfer quota that the subject can declare will be constrained by the boundaries formed by the carbon quota configuration module, and the constraint formula is as follows.

[0108] Q total，k，i，d-1 +Sell i，d ≤Q total，k，i +Q bid，k，i，d-1 ;

[0109] Among them, Q total，i，d-1 Sell ​​represents the total amount of free quotas remaining for the i-th entity in the k-th industry on the d-1 day, which is numerically equal to the total amount of free allocated quotas for the entity minus all the carbon quotas that have been dispatched and transferred before d-1 day; i，d represents the total reported selling volume of the subject on day d; Q bid，k，i，d-1 It indicates the amount obtained by the entity in the auction of the primary carbon emission rights scheduling carried out before d-1. Transfer-out is negative and transfer-in is positive.

[0110] Based on the above constraints, the carbon quota transfer-in amount, carbon quota transfer-out amount and corresponding transfer cost of the reported quota are set for each day in the simulation project time range. Then, the system can simulate the scheduling of secondary carbon emission rights within the full time period based on the cost priority and time priority resource transfer constraint model, and output the clearing resource transfer results of each subject on each day. The specific resource constraint model is as follows.

[0111] Bid_Price n，t，buy ≥Bid_Price m，t，sell ; (1)

[0112]

[0113]

[0114] Carbon emission rights scheduling simulation is usually performed in steps of minutes. When entering the tth moment, a declared transfer-in data and a declared transfer-out data in the existing resource transfer pool are matched to generate a resource transfer data pair, and then judged in sequence according to constraints (1), (2), and (3). When the matched resource transfer data satisfies the three conditions (1), (2), and (3) at the same time, the resource transfer pair is confirmed and included in the clearing result. n，t，buy and Bid_Price m，t，sell They represent the declared resource transfer price of the nth incoming declared data and the declared resource transfer price of the mth outgoing declared data in the full resource transfer pool at time t respectively. This constraint indicates that for this resource transfer data pair, the declared resource transfer price of the incoming declared data must be greater than or equal to the declared resource transfer price of the outgoing declared data before the next constraint judgment can be entered; (2) Bid_Price n，t，buy represents the resource transfer cost of the nth incoming declaration at the tth time, Represents the collection of all transfer-in declarations; Bid_Price m，t，sell represents the declared resource transfer price of the mth transfer-out declaration at the tth time, and θ represents the set of all transfer-out declarations. This constraint indicates that at the tth time, the resource transfer correspondence satisfies that the declared resource transfer price of the transfer-in declaration is greater than or equal to the declared resource transfer price of all other transfer-in declarations, and the declared resource transfer price of the transfer-out declaration should be less than or equal to the declared price of all other transfer-out declarations, that is, the price priority principle. The higher the price of the transfer-in declaration, the higher the priority of the transaction. Similarly, the lower the price of the transfer-out declaration, the higher the priority of resource transfer; (3) Bid_time n，buy and Bid_time m，sell They represent the submission time of the nth transfer-in declaration and the mth transfer-out declaration respectively. The constraint formula indicates that among the two matching transaction parties, the resource transfer declaration time of the transferor-in party should be less than or equal to the resource transfer declaration time of all other transfer-in declarations. The same applies to the transfer-out declaration, that is, the principle of time priority. The earlier the declaration time, the higher the priority of transaction clearance, and finally the transaction price of the secondary carbon market is output.

[0115] For example, as an example of a secondary carbon emission rights scheduling and clearing embodiment, assuming that on day t, the secondary carbon emission rights scheduling time range in the secondary carbon emission rights scheduling model submodule is 9:30-11:30 and 13:30-15:30, and the scheduling subject configuration has 4 scheduling subjects participating in the declaration. The specific declaration information data is as follows:

[0116] Table 3: Information on the entities reporting in the secondary carbon emission rights scheduling

[0117] date time B_name Bid_direction <![CDATA[Bid_price (yuan / tCO2)]]> <![CDATA[Bid_Quantity(tCO2)]]> t 9:35 Body 1 Transfer In 56.35 100 t 10:44 Body 2 Transfer out 56.45 200 t 11:01 Body 1 Transfer In 56.50 150 t 11:05 Body 3 Transfer out 56.65 300 t 14:05 Body 4 Transfer In 56.45 200 t 14:15 Body 1 Transfer In 56.50 500 t 14:56 Body 3 Transfer out 56.48 300

[0118] In the above table, B_name, Bid_direction, Bid_price and Bid_Quantity respectively represent the name of the applicant, the direction of application, the price of the resource transfer and the quota of the resource transfer.

[0119] For the above declaration example, the system automatically clears the results as follows:

[0120] Table 4 Clearing results

[0121]

[0122]

[0123] In the above table, Buyer, Seller, Deal_price, and Deal_Quantity respectively represent the transferee entity name, transferor entity name, transaction price, and transaction quota quantity in the transaction information.

[0124] It can be seen that the system automatically matches and clears based on the price priority and time priority rules. In the example, at 14:05 and 14:15, subject 4 and subject 1 respectively submitted transfer-in applications with resource transfer prices of 56.45 yuan / tCO2 and 56.50 yuan / tCO2. When subject 3 submitted a transfer-out application with a resource transfer price of 56.48 yuan / tCO2 at 14:56, subject 1, as the later applicant, had a superior price, and was given priority in matching and clearing, reflecting the price priority principle. At 14:05, when subject 4 submitted a transfer-in application, since there was still a transfer-out application of 50tCO2 submitted by subject 2 at 10:44, subject 4 was the first subject to submit a price that met the needs of the transferor when it submitted the application. The applications of both parties were concluded, and subject 4 purchased 50tCO2 at the transfer-out price of 56.45 yuan / tCO2 as per subject 2's wishes, reflecting the time priority principle.

[0125] The power dispatching module is used to control the thermal power units in the power dispatching system according to the above-mentioned carbon quota price, and consider the clearing results of power dispatching under the influence of different carbon quota prices.

[0126] The total amount of carbon quota for each thermal power unit can be expressed as follows:

[0127] Q Total =Q free +Q Need =Q free +Q no-free +Q 额外 ;

[0128] Among them, Q Total It is the total amount of carbon quota required by thermal power units, Q free represents the rated carbon quota, Q Need represents paid carbon quota, Q no-free represents the first carbon quota, Q 额外 Indicates the second carbon quota. Rated carbon quota Q free The quota that is not included in the carbon quota price is the quota issued free of charge in the first-level carbon emission scheduling; the paid carbon quota Q Need The quota included in the carbon quota price, paid carbon quota Q Need Including the first carbon quota Q obtained from the auction in the primary carbon emission scheduling no-free , and the second carbon quota Q obtained by quota resource transfer in the secondary carbon emission scheduling 额外 .

[0129] In this embodiment, the system has built-in data management modules, environmental configuration modules, carbon emission scheduling model modules and carbon emission scheduling simulation modules, and has modeled a variety of typical primary and secondary carbon emission scheduling models, combined a variety of scheduling rules to construct a model combination under a variety of scheduling rules, and then, a simulation engineering plan with a year as the time scale can be constructed to simulate the long-term carbon emission rights quota scheduling plan. Based on the carbon quota prices of the primary and secondary carbon emission rights scheduling obtained by the simulation solution of the long-term carbon emission rights quota scheduling plan, combined with the system's built-in safety constraint model taking into account the quota cost, the control of thermal power units is realized, and the SCUC / SCED algorithm is called to clear the clearing results of thermal power units in power scheduling, and the simulation of the power scheduling clearing results of each thermal power unit under the influence of different primary and secondary carbon emission rights scheduling quota costs is realized, supporting the research and analysis of the impact of the quota price of multi-level carbon emission rights scheduling on power scheduling clearing.

[0130] In one embodiment, the carbon quota price corresponding to each unit carbon emission of the thermal power unit is obtained to obtain the unit emission carbon quota price of the thermal power unit, including:

[0131] Step A1: Obtain the total amount of carbon quota Q required for thermal power units Total .

[0132] Step A2, based on the total amount of carbon quota Q Total, the preset primary carbon emission scheduling model and the preset secondary carbon emission scheduling model to determine the rated carbon quota Q of the thermal power unit free and paid carbon quota Q Need .

[0133] For example, the quota allocation model based on the historical carbon emission intensity benchmark is used to calculate the allocation of the total amount of free carbon quota to each entity, and the rated carbon quota Q of the thermal power unit is obtained. free According to the information on whether to participate in the first-level carbon emission rights scheduling and the second-level carbon emission rights scheduling configured in the scheduling subject configuration module, as well as the first-level carbon emission scheduling simulation and the second-level carbon emission scheduling simulation, the first carbon quota of each thermal power unit participating in the first-level carbon emission rights scheduling and the second carbon quota participating in the second-level carbon emission rights scheduling are determined to obtain the paid carbon quota Q Need .

[0134] Step A3: Determine the carbon quota cost corresponding to each unit of carbon emission of the thermal power unit based on the paid carbon quota.

[0135] In this embodiment, the total amount of carbon quota required by the thermal power units is obtained; based on the total amount of carbon quota, the preset primary carbon emission scheduling model and the preset secondary carbon emission scheduling model, the rated carbon quota and paid carbon quota of the thermal power units are determined; according to the paid carbon quota, the carbon quota cost corresponding to each unit of carbon emissions of the thermal power units is determined; through the simulation of the primary and secondary carbon emission quota scheduling, the total amount of carbon quota, rated carbon quota and paid carbon quota corresponding to each thermal power unit can be obtained.

[0136] In one embodiment, according to the paid carbon quota, the carbon quota cost corresponding to each unit of carbon emissions of the thermal power unit is determined, including:

[0137] Step B1, obtaining the first carbon quota price of the first-level carbon emission scheduling model.

[0138] Among them, the first carbon quota price Represents the unit price of carbon quota for primary carbon emission rights scheduling.

[0139] In one implementation, when the first-level carbon emission scheduling model is used to schedule the first-level carbon emission rights, there may be multiple quota schedulings. The carbon quota costs of the first-level carbon emission scheduling model in the multiple carbon quota schedulings are obtained, and the arithmetic average of the carbon quota costs in the multiple carbon quota schedulings is taken to obtain the first carbon quota price.

[0140] For example, when conducting a long-term simulation, there may be multiple auctions for the scheduling of primary carbon emission rights, and the first carbon quota price can be obtained by combining the clearing results of multiple auctions.

[0141] Step B2, combining the first carbon quota price and the paid carbon quota to determine the carbon quota price corresponding to each unit of carbon emissions of the thermal power unit.

[0142] This embodiment obtains the first carbon quota price of the first-level carbon emission scheduling model, combines the first carbon quota price and the paid carbon quota to determine the carbon quota price corresponding to each unit of carbon emissions of the thermal power unit. Based on the simulation of the first-level and second-level carbon emission quota scheduling, the carbon quota price corresponding to each unit of carbon emissions of each thermal power unit can be obtained.

[0143] In one embodiment, the carbon quota price corresponding to each unit of carbon emissions of the thermal power unit is determined in combination with the first carbon quota price and the paid carbon quota, including: when the paid carbon quota of the thermal power unit is less than or equal to the first carbon quota, determining the first ratio, wherein the first ratio is the proportion of the paid carbon quota in the total carbon quota; combining the first carbon quota price and the first ratio to obtain the carbon quota price corresponding to each unit of carbon emissions of the thermal power unit.

[0144] Among them, the following formula can be used to express the carbon quota cost corresponding to each unit of carbon emissions of thermal power units:

[0145] Q Need ≤Q no-free ;

[0146] Among them, the following formula can be used to express the carbon quota cost per unit output of thermal power units:

[0147] Q Need ≤Q no-free ;

[0148] Among them, δ is the carbon emission factor of power generation, tCO2 / MWh, unit, It represents the unit price of carbon quota for the first-level carbon emission rights scheduling, that is, the first carbon quota price, unit cost / tCO2.

[0149] This embodiment determines the first proportion when the paid carbon quota of the thermal power unit is less than or equal to the first carbon quota, and obtains the carbon quota price corresponding to each unit of carbon emissions of the thermal power unit by combining the first carbon quota price and the first proportion. At this time, the thermal power unit does not need to participate in the secondary carbon emission rights scheduling.

[0150] In one embodiment, the first carbon quota price and the paid carbon quota are combined to determine the carbon quota price corresponding to each unit of carbon emissions of the thermal power unit, including: when the paid carbon quota of the thermal power unit is greater than the first carbon quota, obtaining the second carbon quota price of the secondary carbon emission scheduling model, wherein the second carbon quota price is the price of the unit carbon quota when determining the second carbon quota; determining the second ratio, wherein the second ratio is the ratio of the first carbon quota to the sum of the rated carbon quota and the first carbon quota; combining the first carbon quota price, the second ratio and the second carbon quota price to obtain the carbon quota price corresponding to each unit of carbon emissions of the thermal power unit.

[0151] Among them, the following formula can be used to express the carbon quota cost corresponding to each unit of carbon emissions of thermal power units:

[0152] Q Need >Q no-free ;

[0153] Among them, the following formula can be used to express the carbon quota cost per unit output of thermal power units:

[0154] Q Need >Q free ;

[0155] Among them, δ is the carbon emission factor of power generation, It is the unit carbon quota price at the tth moment on the dth day of the mth month in the secondary carbon emission rights scheduling, that is, the second carbon quota price, unit cost / tCO2.

[0156] This embodiment constructs a primary carbon emission scheduling model and a secondary carbon emission scheduling model by combining different carbon quota resource transfer rules, and configures the resource transfer subject information in the market environment to build an environment configuration plan. Within the time range of the custom-set simulation project, the carbon quota boundary and subject participation are configured, and the declared data is matched and cleared based on the cost priority and time priority rules. The primary carbon emission rights scheduling and the secondary carbon emission rights scheduling are simulated in turn, and the full clearing results within the simulation time range are output, including the paid carbon quota, rated carbon quota, first carbon quota and second carbon quota of each thermal power unit. At the same time, the unit carbon quota cost of the primary carbon emission rights scheduling and the secondary carbon emission rights scheduling is obtained, so that the carbon quota cost corresponding to each unit carbon emission of the power unit can be determined.
