Description

Technical Field

[0001] The present invention relates to the technical field of green energy, and specifically to a simulation and deduction system for the operation of a power market with coordinated green value. Background Art

[0002] In the current power market, the accuracy of carbon emission data is of great significance to the industry development and environmental protection decision-making. At present, the emission factor method, the mass balance method, and the actual measurement method are commonly used carbon emission accounting means. Among them, the actual measurement method relies on analyzing the actual data obtained by deploying sensors, and then obtaining the corresponding results. However, during the process of monitoring or transmitting data by the sensors, problems such as data loss may occur due to reasons such as equipment or network failures. Although there are currently various technologies for correcting the missing data, the actual situation of power enterprises in the carbon emission process and the historical carbon emission rules are not taken into account, resulting in the corrected data deviating from the actual situation from time to time. Summary of the Invention

[0003] The purpose of the present invention is to provide a simulation and deduction system for the operation of a power market with coordinated green value to solve the problems raised in the prior art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] A simulation and deduction system for the operation of a power market with coordinated green value, including a feature record extraction module, a deviation range calculation module, a data correction module, and an early warning and prompt module;

[0006] The feature record extraction module: used to obtain the historical carbon emission records of power enterprises, where the power enterprises are thermal power enterprises that generate electricity by burning carbon-containing energy fuels; monitor the carbon content and power generation at each moment during the power generation process through sensors, establish a carbon content line chart and a power generation line chart corresponding to each carbon emission record, and analyze the carbon content line chart and the power generation line chart to extract feature records from the carbon emission records;

[0007] The deviation range calculation module: used to analyze the changes in carbon content and power generation at the same moment in the corresponding carbon content line chart and power generation line chart in the feature records, calculate the first deviation coefficient and the second deviation coefficient corresponding to the feature records, and then obtain the deviation range according to the first deviation coefficient and the second deviation coefficient;

[0008] The data correction module: used to obtain the carbon emission records after transmitting the current sensor data to a computer program, analyze the carbon content and power generation in the carbon emission records to obtain the data with abnormal carbon content, and correct the abnormal data through data correction technology, and use the corrected value as the virtual carbon content;

[0009] Early warning prompt module: used to obtain the early warning coefficient of the corrected data according to the corrected virtual carbon content, and judge whether to give an early warning to the data correction technology according to the early warning coefficient, and prompt relevant personnel to correct again.

[0010] Furthermore, the feature record extraction module includes a carbon content line chart establishment unit, a power generation line chart establishment unit, and a feature record extraction unit;

[0011] In this solution, the power enterprise is a thermal power enterprise that generates electricity by burning carbon-containing energy fuels. Thermal power usually uses fossil fuels such as coal, oil, and natural gas as energy. These fossil fuels are deposited from the fossils of ancient organisms and contain a large amount of carbon elements. For thermal power plants, a large amount of carbon dioxide will be emitted during the combustion of fossil fuels such as coal. In order to monitor the emission situation and carry out environmental protection control, sensors generally have a fixed acquisition frequency;

[0012] Carbon content line chart establishment unit: used to deploy a carbon content sensor at the pollutant emission port of the power enterprise, randomly extract the time period F during the power generation process corresponding to a certain historical carbon emission record; obtain the acquisition frequency of the carbon content sensor, and get the interval duration g between two adjacent carbon content data acquisitions. According to the interval duration g, collect the carbon content data of the carbon content sensor within the time period F. The number of carbon content data is m = F / g, and transmit it to the computer program to establish a carbon content line chart;

[0013] Power generation line chart establishment unit: used to deploy a power generation sensor for monitoring the power generation during the power generation process at the outlet end of the generator, obtain the acquisition frequency of the power generation sensor, and get the interval duration h between two adjacent power generation data acquisitions. According to the interval duration h, collect the power generation data of the power generation sensor within the time period F. The number of power generation data is n = F / h, and transmit it to the computer program to establish a power generation line chart.

[0014] According to the carbon content generated in real time at each moment during the power generation process, a carbon content line chart is obtained. According to the power generation generated in real time at each moment, a power generation line chart is obtained; generally, due to the instantaneity of energy conversion, thermal power generation is a process of converting chemical energy into thermal energy and then into electrical energy by burning fossil fuels. In this process, the release of carbon dioxide and the generation of electrical energy by fuel combustion occur simultaneously. When the power generation increases, it means that more fuel is burned at the same moment, and inevitably more carbon dioxide emissions will be generated at the same time, so the carbon emissions will also immediately increase; conversely, when the power generation decreases, the fuel combustion amount decreases, and the carbon emissions will also immediately decrease. Therefore, generally speaking, the power generation line chart and the carbon content line chart of the thermal power plant move up and down together;

[0015] Further, the feature record extraction unit: according to the numerical values of each element in the carbon content line graph and the power generation line graph, the dynamic time warping method is used to obtain the DTW distance between the two line graphs. If the DTW distance is less than the preset distance threshold and the numerical values of each element in the carbon content line graph and the power generation line graph are greater than 0, a certain carbon emission record is used as a feature record, and then all feature records are obtained.

[0016] Further, the deviation range calculation module includes a feature record analysis unit and a deviation range calculation unit;

[0017] The feature record analysis unit: used to obtain the carbon emission line graph L corresponding to a certain feature record c and the power generation line graph L e , the total time period corresponding to the line graph L c and L e is both F; randomly obtain Q moments from the time period F, obtain the ratio of the carbon content to the power generation corresponding to each moment, a total of Q ratios are obtained, and the minimum value and the maximum value of the ratios are extracted; then the minimum value and the maximum value of the ratios corresponding to each feature record are obtained.

[0018] Dynamic Time Warping (DTW) is an algorithm used to measure the similarity between two time series. It is a prior art, including steps such as constructing a distance matrix, initializing the cumulative distance matrix, filling the cumulative distance matrix, and calculating the DTW distance, which will not be elaborated here. The advantage of dynamic time warping is that it can effectively handle the similarity calculation between time series with different lengths. In this solution, due to the different acquisition frequencies of the carbon content sensor and the power generation sensor, the number of elements in the obtained carbon content line graph and power generation line graph is also different, which are m and n respectively. Therefore, using dynamic time warping here can more conveniently and quickly obtain the DTW distance between the two line graphs. Since the larger the DTW distance, the greater the difference between the two sequences in time, that is, the smaller the similarity between the two line graphs. Therefore, the smaller the DTW distance here, and the numerical values of each element in the carbon content line graph and the power generation line graph are greater than 0, indicating that the carbon emission record conforms more to the actual change law. Therefore, this part of the carbon emission record is used as a feature record;

[0019] Further, the deviation range calculation unit: uses the total number of feature records as D, extracts the recording moments corresponding to each feature record, and sorts the feature records from 1 to D in the order of the recording moments from front to back, and adds up all the serial numbers to obtain the serial number sum S D , and then obtains the weight of the feature record with the serial number d as W d =d / S D, where \(1\leq d\leq D\); for each feature, record the corresponding minimum ratio value, maximum ratio value, and weight value, and obtain the first deviation coefficient as , where \(R\) min d is the minimum ratio value of the feature record with serial number \(d\), and obtain the second deviation coefficient as , where \(R\) max d is the maximum ratio value of the feature record with serial number \(d\), and further obtain the deviation range as \([R1, R2]\).

[0020] Furthermore, the data correction module includes a to-be-detected set determination unit, an objective function establishment unit, and a data correction unit;

[0021] To-be-detected set determination unit: used to extract the carbon content and power generation amount at each moment in the current carbon emission record; where the next moment of a certain moment \(a\) is \(b\), if the difference in carbon content between moment \(a\) and moment \(b\) is greater than the preset difference threshold, or the ratio result of the carbon content at moment \(a\) to the power generation amount is not within the deviation range, then mark moment \(a\); obtain all the marked moments, and take all adjacent marked moments as a to-be-detected set, and obtain several to-be-detected sets.

[0022] Here, for the reliability of data calculation, the power generation sensor is a sensor that has passed the inspection and has a qualified quality inspection result.

[0023] Furthermore, the objective function establishment unit: used to take the moment before the earliest moment in a certain to-be-detected set as \(T1\), the moment after the latest moment as \(T2\), and take a certain moment in a certain to-be-detected set as \(T\) x ; take the actual carbon content corresponding to moment \(T1\), moment \(T2\), and moment \(T\) x as \(C1\), \(C2\), and \(C\) x ; establish an objective function for the change of carbon content with time, and mark the position points \((T1, C1)\) and \((T2, C2)\) in the objective function, and connect the two position points to obtain line segment \(S\);

[0024] Furthermore, the data correction unit: used to obtain the carbon content \(C\) corresponding to line segment \(S\) when the moment is \(T\) x ; take the actual power generation amount at moment \(T\) x 、 as \(E\) x , and according to the carbon content \(C\) x and \(C\) x and \(C\) x 、 , if it satisfies that the ratio of \(C\) x divided by \(E\) x is outside the deviation range and \(C\) x 、 divided by \(E\)x If the ratio is within the deviation range, the actual carbon content C x is regarded as abnormal data; then all abnormal data are obtained, and all abnormal data are corrected according to the data correction technology, and the corrected value is used as the virtual carbon content.

[0025] Existing data correction technologies include many, such as mean filling method, K-nearest neighbor algorithm, multi-source data fusion correction, etc. If only the data itself is concerned when correcting data without combining the actual change law, it will lead to deviations in the correction results of the data correction technology and cannot accurately present the change trend of carbon content. Therefore, in this solution, it is necessary to analyze according to the power generation and the corresponding deviation range between the power generation and the carbon content to ensure the reliability of data calculation;

[0026] Furthermore, the early warning prompt module includes an early warning prompt unit;

[0027] Early warning prompt unit: used to obtain a certain corrected virtual carbon content y0, and the carbon contents y1 and y2 adjacent to the time corresponding to the virtual carbon content y0 before and after, respectively obtain the power generations z0, z1, and z2 at the times corresponding to the carbon contents y0, y1, and y2, obtain the vector Y = (y1, y0, y2) and the vector Z = (z1, z0, z2), and obtain the cosine similarity between the vector Y and the vector Z as the eigenvalue corresponding to the carbon content y0, and then obtain the eigenvalues corresponding to several virtual carbon contents, and add them up and take the average as the early warning coefficient of the data correction technology. If the early warning coefficient is less than the preset coefficient threshold, an early warning prompt is given to the current data correction technology, and relevant personnel are prompted to correct it again.

[0028] Cosine similarity is a method to measure the similarity between two vectors in a vector space. It is calculated based on the cosine value of the angle between vectors, and the value range is [-1, 1]. When the cosine similarity is 1, it means that the two vectors are exactly the same, which is the most similar situation; when the cosine similarity is -1, it means that the two vectors are in exactly opposite directions, which is the most dissimilar situation; when the cosine similarity is 0, it means that the two vectors are perpendicular to each other and have no similarity. Therefore, the closer to 1, the more similar the two vectors are.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention provides a simulation and deduction system for the operation of a power market with coordinated green value, including: a feature record extraction module, which is used to obtain the historical carbon emission records of power enterprises, and extract feature records from the carbon emission records according to the carbon content and power generation amount in the carbon emission records; a deviation range calculation module, which is used to analyze the changes in carbon content and power generation amount in the feature records to obtain a deviation range; a data correction module, which is used to obtain the current carbon emission records, obtain the data with abnormal carbon content therein, and correct it; an early warning prompt module, which is used to judge whether to give an early warning to the data correction technology according to the corrected virtual carbon content. By summarizing the historical carbon emission rules and analyzing the current carbon content correction data, the present invention judges whether the current data correction technology needs to be prompted, which helps to improve the accuracy and rationality of the current data repair.

[0032] Embodiment: As Figure 1 shown, the present invention provides a technical solution for a simulation and deduction system for the operation of a power market with coordinated green value, including a feature record extraction module, a deviation range calculation module, a data correction module, and an early warning prompt module;

[0033] The feature record extraction module: It is used to obtain the historical carbon emission records of power enterprises, and the power enterprises are thermal power enterprises that generate electricity by burning carbon-containing energy fuels; monitor the carbon content and power generation amount at each moment during the power generation process through sensors, establish a carbon content line graph and a power generation amount line graph corresponding to each carbon emission record, and analyze the carbon content line graph and the power generation amount line graph to extract feature records from the carbon emission records;

[0034] The feature record extraction module includes a carbon content line graph establishment unit, a power generation amount line graph establishment unit, and a feature record extraction unit;

[0035] In this solution, the power enterprise is a thermal power enterprise that generates electricity by burning carbon-containing energy fuels. Thermal power generation usually uses fossil fuels such as coal, oil, and natural gas as energy sources. These fossil fuels are deposited from the fossils of ancient organisms and contain a large amount of carbon elements. For thermal power plants, a large amount of carbon dioxide is emitted during the combustion of fossil fuels such as coal. In order to monitor the emission situation and conduct environmental protection control, sensors generally have a fixed acquisition frequency. In this embodiment, the carbon content sensor has an acquisition frequency of 10 seconds per time, and the power generation sensor has an acquisition frequency of 12 seconds per time. The actual sensor acquisition frequency depends on the actual situation.

[0036] Carbon content line graph establishment unit: used to deploy a carbon content sensor at the pollutant emission outlet of the power enterprise, randomly extract the time period F during the power generation process corresponding to a certain historical carbon emission record; obtain the acquisition frequency of the carbon content sensor, and get the interval duration g between two adjacent carbon content data acquisitions. According to the interval duration g, collect the carbon content data of the carbon content sensor during the time period F. The number of carbon content data is m = F / g, and transmit it to the computer program to establish a carbon content line graph;

[0037] Power generation line graph establishment unit: used to deploy a power generation sensor for monitoring the power generation during the power generation process at the generator outgoing terminal, obtain the acquisition frequency of the power generation sensor, and get the interval duration h between two adjacent power generation data acquisitions. According to the interval duration h, collect the power generation data of the power generation sensor during the time period F. The number of power generation data is n = F / h, and transmit it to the computer program to establish a power generation line graph;

[0038] According to the carbon content generated in real time at each moment during the power generation process, a carbon content line graph is obtained. According to the power generation generated in real time at each moment, a power generation line graph is obtained; Generally, due to the instantaneity of energy conversion, thermal power generation is a process of converting chemical energy into thermal energy and then into electrical energy by burning fossil fuels. In this process, the release of carbon dioxide and the generation of electrical energy by fuel combustion occur simultaneously. When the power generation increases, it means that more fuel is burned at the same moment, and inevitably more carbon dioxide emissions will be generated at the same time, so the carbon emissions will also immediately rise; conversely, when the power generation decreases, the fuel combustion amount decreases, and the carbon emissions will also immediately decrease. Therefore, generally speaking, the power generation line graph and the carbon content line graph of the thermal power plant move up and down together.

[0039] Characteristic record extraction unit: used to obtain the DTW distance between the two line graphs using the dynamic time warping method according to the numerical values of each element in the carbon content line graph and the power generation line graph. If the DTW distance is less than the preset distance threshold and the numerical values of each element in the carbon content line graph and the power generation line graph are both greater than 0, then a certain carbon emission record is used as a characteristic record, and then all characteristic records are obtained.

[0040] Dynamic Time Warping (DTW) is an algorithm used to measure the similarity between two time series. It is an existing technology, including steps such as constructing a distance matrix, initializing a cumulative distance matrix, filling the cumulative distance matrix, and calculating the DTW distance, which will not be elaborated here. The advantage of dynamic time warping is that it can effectively handle the similarity calculation between time series of different lengths. In this solution, since the acquisition frequencies of the carbon content sensor and the power generation sensor are different, the number of elements in the carbon content line chart and the power generation line chart obtained is also different, which are m and n respectively. Therefore, using dynamic time warping here can more conveniently and quickly obtain the DTW distance between the two line charts. Since the larger the DTW distance, the greater the difference between the two sequences in time, that is, the smaller the similarity between the two line charts, the smaller the DTW distance here, and the value of each element in the carbon content line chart and the power generation line chart is greater than 0, indicating that the carbon emission record conforms more to the actual change law. Therefore, this part of the carbon emission record is used as a feature record.

[0041] Deviation range calculation module: It is used to analyze the changes in carbon content and power generation at the same moment in the corresponding carbon content line chart and power generation line chart of the feature record, calculate the first deviation coefficient and the second deviation coefficient corresponding to the feature record, and then obtain the deviation range based on the first deviation coefficient and the second deviation coefficient;

[0042] The deviation range calculation module includes a feature record analysis unit and a deviation range calculation unit;

[0043] Feature record analysis unit: It is used to obtain the carbon emission line chart L c and the power generation line chart L e corresponding to a certain feature record. The total time period corresponding to the line charts L c and L e is both F; Randomly obtain Q moments from the time period F, obtain the ratio of the carbon content to the power generation corresponding to each moment, a total of Q ratios are obtained, and the minimum value and the maximum value of the ratios are extracted; Then, the minimum value and the maximum value of the ratio corresponding to each feature record are obtained;

[0044] Deviation range calculation unit: It is used to take the total number of feature records as D, extract the recording moments corresponding to each feature record, sort the feature records from 1 to D in the order of the recording moments from front to back, and add up all the serial numbers to obtain the serial number sum S D . Then, the weight of the feature record with the serial number d is W d =d / S D , where 1≤d≤D; According to the minimum value, the maximum value of the ratio, and the weight corresponding to each feature record, the first deviation coefficient is obtained as , where R min d is the minimum value of the ratio of the feature record with serial number d, and the second deviation coefficient is obtained as , where R max d is the maximum value of the ratio of the feature record with serial number d, and then the deviation range is obtained as [R1, R2].

[0045] Data correction module: It is used to obtain the carbon emission record after transmitting the current sensor data to the computer program, analyze the carbon content and power generation amount in the carbon emission record, obtain the data with abnormal carbon content, and correct the abnormal data through data correction technology, and use the corrected value as the virtual carbon content.

[0046] The data correction module includes a to-be-detected set determination unit, an objective function establishment unit, and a data correction unit;

[0047] To-be-detected set determination unit: It is used to extract the carbon content and power generation amount at each moment in the current carbon emission record; among them, the next moment of a certain moment a is b. If the difference in carbon content between moment a and moment b is greater than the preset difference threshold, or the ratio result of the carbon content and power generation amount at moment a is not within the deviation range, then moment a is marked; all the marked moments are obtained, and all adjacent marked moments are used as a to-be-detected set, and several to-be-detected sets are obtained.

[0048] Objective function establishment unit: It is used to use the moment before the earliest moment in a to-be-detected set as T1, the moment after the latest moment as T2, and a certain moment in a to-be-detected set as T x ; use the actual carbon content corresponding to moment T1, moment T2, and moment T x as C1, C2, and C x ; establish an objective function for the change of carbon content over time, and mark the position points (T1, C1) and (T2, C2) in the objective function, and connect the two position points to obtain line segment S.

[0049] Data correction unit: It is used to obtain the carbon content C x corresponding to line segment S when the moment is T x 、 ; use the actual power generation amount at moment T x as E x , and according to the carbon content C x and C x 、 , if it satisfies that the ratio of C x divided by E x is outside the deviation range and C x 、 divided by Ex If the ratio is within the deviation range, the actual carbon content C x is regarded as abnormal data; then all abnormal data are obtained, and all abnormal data are corrected according to the data correction technology, and the corrected value is used as the virtual carbon content.

[0050] There are many existing data correction technologies, such as mean filling method, K-nearest neighbor algorithm, multi-source data fusion correction, etc. If only the data itself is concerned when correcting data without combining the actual change law, it will lead to deviation in the correction results of the data correction technology and cannot accurately present the change trend of carbon content. Therefore, in this solution, it is necessary to analyze according to the power generation and the corresponding deviation range between the power generation and the carbon content to ensure the reliability of data calculation.

[0051] Early warning prompt module: used to obtain the early warning coefficient of the corrected data according to the corrected virtual carbon content, and judge whether to give an early warning to the data correction technology according to the early warning coefficient, and prompt relevant personnel to correct again.

If the early warning coefficient is less than the preset coefficient threshold, give an early warning prompt to the current data correction technology and prompt relevant personnel to correct again.

[0054] Cosine similarity is a method to measure the similarity between two vectors in a vector space. It is calculated based on the cosine value of the angle between vectors, and the value range is [-1,1]. When the cosine similarity is 1, it means that the two vectors are exactly the same, which is the most similar situation; when the cosine similarity is -1, it means that the two vectors are in completely opposite directions, which is the least similar situation; when the cosine similarity is 0, it means that the two vectors are perpendicular to each other and have no similarity. Therefore, the closer to 1, the more similar the two vectors are. In this embodiment, the preset coefficient threshold is 0.9.
