DETAILED DESCRIPTION

[0018] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the specific implementation method, structure, features and effects of a method and system for urban centralized heating data management proposed by the present invention in combination with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0019] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0020] The specific scheme of a method and system for managing urban centralized heating data provided by the present invention is described in detail below with reference to the accompanying drawings. Example

[0021] See also Figure 1 , which shows a flow chart of a method for managing urban centralized heating data provided by an embodiment of the present invention, including: S101, obtaining gas consumption of different types of users in different areas of a city during different collection time periods.

[0022] Specifically, the city's central heating system is an energy system that uses a centralized approach to provide winter heating for cities or large areas, and is generally composed of heat sources, heating pipe networks, and users. In order to ensure the efficient operation of the central heating system, a central dispatch and control system is usually provided, wherein the region in the embodiment of the present invention may be an area in a city. The length of the collection time period in the embodiment of the present invention can be determined based on actual conditions. The value in the embodiment of the present invention is 1 week, and the collection cycle can generally be 4 months. Among them, the embodiment of the present invention obtains the weekly historical gas consumption of all users in different areas through the relevant gas supply company or energy management platform. After acquiring the data, due to the large size of the data, it needs to be cleaned and the missing values ​​filled in to ensure its integrity and consistency. For example, such as Figure 2 As shown, Figure 2 A curve diagram of gas consumption changing over time is provided for an embodiment of the present invention. Generally speaking, users who enjoy heating in a certain area are divided into residential users, public institutions, commercial users, and industrial users. Different types of users have different corresponding weekly gas consumption. For example, the weekly gas consumption of commercial and industrial users is generally greater than that of residential users. Therefore, Figure 2The gas consumption of all users in the system presents a step-by-step distribution. Based on this, the embodiment of the present invention analyzes the step-by-step distribution characteristics of gas consumption to evaluate the heating demand of different areas to optimize the scheduling of heating resources.

[0023] S102, mapping the average gas consumption of each type of users in each area in each collection time period into a coordinate system to obtain a plurality of mapping points.

[0024] Specifically, there may be multiple types of heating users in different areas, and different types of users have different weekly gas consumption. In order to determine the heating gas demand in the corresponding area, it is necessary to analyze the corresponding gas consumption scale under different gradients for evaluation. Therefore, the embodiment of the present invention divides the gas consumption in different areas into gradients. Generally, the gas consumption of residential user terminals is relatively low and the number is large, so the corresponding data curves are generally densely distributed at a lower level, while other users such as public institutions have different gradients of gas consumption due to differences in volume, but the overall consumption is greater than that of residential user terminals, so the corresponding data curves are generally distributed above the data curves corresponding to residential user terminals.

[0025] Furthermore, the embodiment of the present invention first calculates the average consumption of a user in a collection period according to the historical gas consumption of a user in a region during the collection period, and specifically uses the following formula for calculation: ; In the above formula, Represents the average gas consumption of a user during the collection period. Representative Gas consumption during each collection period, Represents the number of collection time periods. Different users in this area will have an average gas consumption.

[0026] Furthermore, the average gas consumption of all users is mapped to a coordinate system, where the horizontal axis of the coordinate system is time and the vertical axis of the coordinate system is the average gas consumption. Then the average gas consumption of different users corresponds to a data point on the y-axis, thus obtaining multiple mapping points.

[0027] S103, dividing the mapping point sequence in the coordinate system according to the average gas consumption difference between adjacent mapping points in each area and the average gas consumption corresponding to each mapping point, to obtain multiple gas consumption sequences of the area.

[0028] Among them, different gas consumption sequences correspond to different gradients.

[0029] Specifically, the data points corresponding to the same gas consumption gradient are more concentrated, and the data points between different gas consumption gradients are more different. Therefore, the differences between any adjacent mapping points can be analyzed to divide the gradient.

[0030] Further, when segmenting the mapping point sequence in the coordinate system, as an optional embodiment of the present invention, first use The function traverses the mapping point sequence and calculates the difference between the average gas consumption between adjacent mapping points to obtain the difference in average gas consumption between adjacent mapping points; then selects the maximum difference value from the differences in average gas consumption between adjacent mapping points in the area; finally determines the smaller of the average gas consumptions corresponding to the adjacent mapping points corresponding to the maximum difference value, and takes a predetermined number of mapping points before the smaller one and performs segmentation.

[0031] Specifically, the embodiment of the present invention utilizes The function filters and segments all mapping point sequences in the coordinate system, where the formula for the number of filtered mapping points is as follows: ; In the above formula, is the number of filtered mapping points, that is, the predetermined number. The parameter represents the maximum average gas consumption difference between any two adjacent mapping points. Parameter Representation The function starts executing from the first mapping point in the sequence. Indicates the average gas consumption corresponding to the first mapping point. Indicates the average gas consumption corresponding to the i+1th mapping point. Indicates the average gas consumption corresponding to the i-th mapping point. In this embodiment, the mapping points are set to increase in sequence from bottom to top. That is, through The function is used to traverse the sequence, calculate the difference between any two adjacent mapping points, and then count the two points corresponding to the maximum difference. The smaller of the values ​​and the number of previous data points is The sequence is segmented. The two segments are segmented using this method in an iterative manner in an up-down order. Multiple gas consumption sequences of the region are obtained.

[0032] It is worth noting that in the process of cutting, the iteration stop condition is defined at the same time. In the embodiment of the present invention, all the mapping points in each sequence are denser after the iteration stops, that is, the average gas consumption of users in each gradient is more similar. According to experience, if the ratio of the maximum value of the average gas consumption difference in the sequence after a certain iteration to the average value of the average gas consumption difference is If no sequence segmentation is performed, each gas consumption sequence obtained at this time can be used as a gradient, and the corresponding area will obtain multiple gas consumption gradients for the user. Indicates the maximum value of the average gas consumption difference, Indicates the average value of the average gas consumption differences.

[0033] S104, determining the heating priority number of the area according to the gas consumption of the users corresponding to the gas consumption sequences of each gradient in the area.

[0034] Specifically, for users in any area, there are different numbers of users under different gas consumption gradients, but for this prefecture-level city, there may be multiple areas with similar gas consumption corresponding to a certain gradient. In the subsequent evaluation of heating demand, heating resources can be centrally dispatched for these areas according to demand. Among them, the heating priority ordinal number refers to the heating priority of each area. The larger the heating priority ordinal number, the higher the priority of the corresponding area, and it needs to be heated first.

[0035] Further, when determining the heating priority ordinal number of a region, as an optional embodiment of the present invention, first, the comprehensive gas consumption level corresponding to the gas consumption sequence in the region is determined according to the gas consumption of the users corresponding to the gas consumption sequence in the region; then, the fluctuation similarity of the gas consumption of the two gradients in any two regions with the same gradient number is determined according to the gas consumption in the gas consumption sequence in any two regions with the same gradient number; secondly, the confidence of the two gradients as the same category is determined according to the fluctuation similarity of the gas consumption of the two gradients in the two regions with the same gradient number and the comprehensive gas consumption level corresponding to the two gradients; and the regions corresponding to the two gradients with confidence greater than the first threshold in the two regions with the same gradient number are selected to belong to the same first category; then, the regions with the same gradient number are divided into a block group, and the degree of merging between any two gradients in different block groups is determined according to the first average gas consumption of the users included in any two gradients in the adjacent block groups; and it is determined that the regions corresponding to any two gradients with a degree of merging less than or equal to the second threshold belong to the same second category; finally, the heating priority ordinal number of the region is determined according to the first gas consumption of all users in the second category to which the region belongs in all gradients, the second gas consumption of all users in the first category to which the region belongs in the gradient, and the gradient value corresponding to the region.

[0036] Specifically, when calculating the comprehensive gas consumption level, the embodiment of the present invention, as an optional embodiment of the present invention, firstly calculates the second average gas consumption of the gas consumption of all users corresponding to the gas consumption sequence; then determines the maximum gas consumption and the minimum gas consumption of the users in the area, and the first difference between the maximum gas consumption and the minimum gas consumption; finally, calculates the first ratio between the first average gas consumption and the first difference to obtain the comprehensive gas consumption level corresponding to the gas consumption sequence.

[0037] The embodiment of the present invention specifically uses the following formula to calculate the comprehensive gas consumption level corresponding to the gas consumption sequence: ; In the above formula, It is the comprehensive gas consumption level corresponding to the gas consumption sequence corresponding to the gradient in a certain area. For this gradient Average gas consumption per user, The number of users included for this gradient. and are the maximum and minimum gas consumption of users in this area. The second average gas consumption of all users corresponding to the gas consumption sequence of this gradient is represented. The larger the value, the higher the comprehensive gas consumption level corresponding to this gradient. represents the extreme difference in gas consumption of all users in this area, then The larger the value is, the higher the average gas consumption corresponding to this gradient accounts for the maximum gas consumption range of the entire area, which means that the overall gas consumption of users within this gradient is greater and the comprehensive gas consumption level is greater.

[0038] Therefore, the corresponding comprehensive gas consumption level is calculated for all gradients in any region by the above-mentioned embodiment of the present invention. Then clustering can determine the category by the similarity of the comprehensive gas consumption level of the corresponding gradients in different regions.

[0039] Further, for any two regions with the same gradient number, as an optional embodiment of the present invention, determining the fluctuation similarity of gas consumption of two gradients in any two regions with the same gradient number according to the gas consumption in the gas consumption sequence in the any two regions with the same gradient number includes: respectively calculating a second ratio between the maximum average gas consumptions in the gas consumption sequences corresponding to the two gradients, and a third ratio between the minimum average gas consumptions in the gas consumption sequences corresponding to the two gradients; calculating a first product between the second ratio and the third ratio to obtain the fluctuation similarity of gas consumption of the two gradients in the region.

[0040] Specifically, the embodiment of the present invention uses the following formula to calculate the fluctuation similarity of the gas consumption of two gradients in any two regions with the same gradient number: ; In the above formula, Represents the corresponding gradients in two regions with the same gradient number With gradient The fluctuation similarity of gas consumption. For gradient Maximum average gas consumption. For gradient Minimum average gas consumption. For gradient Maximum average gas consumption. For gradient The minimum average gas consumption in . Therefore It represents the difference in the fluctuation range of the gas consumption of users included in the two gradients. The smaller the value, the more similar the fluctuation range of the gas consumption of the two gradients, and the greater the possibility of clustering into one category.

[0041] Furthermore, when determining the confidence that two gradients are of the same category, as an optional embodiment of the present invention, the absolute value of the second difference between the comprehensive gas consumption levels corresponding to the two gradients and the second product between the absolute value of the second difference and the fluctuation similarity are first calculated; then the inverse of the second product is normalized to obtain the confidence that the two gradients are of the same category.

[0042] Specifically, the embodiment of the present invention specifically uses the following formula to calculate two gradients as the confidence of the same category: ; In the above formula, For gradient With gradient As the confidence of the same category. Represents the corresponding gradients in two regions with the same gradient number With gradient The fluctuation similarity of gas consumption. Represents the gradient With gradient The similarity of the comprehensive gas consumption levels. represents a normalization function, which is used to normalize the result to the range of [0, 1], which can be specifically, for example, maximum and minimum value normalization.

[0043] Furthermore, the first threshold value can be selected according to actual conditions. In the embodiment of the present invention, the first threshold value is set to 0.88. The corresponding two gradients can be considered to belong to the same category. Finally, for all regions with the same number of gradients, the corresponding confidence is calculated by the above method and classified.

[0044] It should be noted that the clustering object here is the area where the gradient is located. Since there are multiple gradients in an area, the clustering is to judge the areas with the same gradient layer, that is, to perform similarity clustering on all areas corresponding to the same gradient layer based on confidence. So far, similarity clustering is performed on each layer of gradients in all areas with the same gradient, and all areas with the same number of gradients are set as a district group. However, since it is impossible for all areas in a prefecture-level city to have the same gas consumption gradient, if there are multiple different types of user terminals in some areas, the corresponding gas consumption gradients will be more. The above method only obtains clustering results for all areas with the same gradient, and the scheduling of heating gas resources needs to be planned based on the needs of all areas in the entire prefecture-level city. Therefore, it is necessary to merge the clustering results of all different gradient areas to obtain the gas consumption scale gradient of the entire city.

[0045] Furthermore, the embodiment of the present invention adopts a method of merging gradients from small to large levels, starting from the first-level block group with the least number of gradients, analyzing the similarity of the gas consumption of a certain layer of gradients with the gas consumption of each layer of gradients in the next level of gradients for merging, and then by analogy, gradually merging the blocks with small gradients into the blocks with large gradients. Then, the gradient clustering result of the gas consumption scale of the entire city can be obtained.

[0046] Furthermore, when determining the degree of merging between any two gradients in different groupings, as an optional embodiment of the present invention, the absolute value of the third difference between the first average gas consumption of users included in any two gradients is calculated to obtain the degree of merging between any two gradients in different groupings.

[0047] Specifically, the embodiment of the present invention can use the following formula to calculate the degree of merging between any two gradients: ; In the above formula, For the Gradients in the block group With Gradients in the block group degree of merger. For the Gradients in the block group The first average gas consumption of all users included in . For the Gradients in the block group The first average gas consumption of all users included in . Represents the normalization function, which is used to Perform normalization.

[0048] It should be noted that i in this scheme specifically represents the order and has no physical meaning. The parameter that truly represents the physical meaning is For example, if i is 1, it means the first block group. The formula represents the average gas consumption of the first mapping point.

[0049] Furthermore, the second threshold value may be set to 0.2. In the embodiment of the present invention, the second threshold value is recorded as . Select here The corresponding two gradients are merged, that is, the merged object is the area corresponding to this gradient, that is, the areas corresponding to any two gradients are divided into the same second category.

[0050] Furthermore, when allocating heating resources, priority is given to heating for residents' daily life, followed by heating for production. The gas consumption of residential user terminals is generally at a lower gradient, while the gas consumption of industrial and commercial institutions is at a higher gradient. Therefore, for any region, the lower its gradient distribution in the city's gas consumption scale gradient and the larger the scale of the clustering result, the higher its priority for heating demand, and vice versa. Therefore, as an optional embodiment of the present invention, determining the heating priority ordinal number of a region according to the first gas consumption of all users in the second category to which the region belongs in all gradients, the second gas consumption of all users in the first category to which the region belongs in the gradient, and the gradient value corresponding to the region includes: calculating the fourth ratio between the second gas consumption and the first gas consumption, and the inverse of the superposition value of the gradient values ​​of all gradients corresponding to the region; calculating the third product between the fourth ratio and the inverse of the superposition value, and taking the average value of the third product corresponding to each gradient to obtain the heating priority ordinal number of the region.

[0051] Specifically, the embodiment of the present invention specifically uses the following formula to calculate the heating priority number: ; In the above formula, Represents the heating priority number of a certain area. It is the first gas consumption of all users in the cluster category to which the region belongs in all gradients of the region, that is, the first gas consumption of all users in the second category to which the region belongs in all gradients. For this reason, the region The gas consumption of all users in the cluster category to which the layer gradient belongs, that is, the second gas consumption of all users in the first category to which the gradient belongs. Represents the gradient value corresponding to a certain gradient in this area. represents the superposition of the gradient values ​​corresponding to all the gradients in the region. Represents this region The ratio of the scale of the cluster category in the layer gradient to the scale of all gradients. The larger the value, the larger the gas consumption scale in the area with lower gradient. The larger the value of the heating priority ordinal number, the higher the corresponding priority. It represents the distribution of this area in different gradients. The smaller the value, the larger the gradient value in this area. The higher the gradient distribution, the smaller the heating priority ordinal value, and the lower the corresponding priority.

[0052] So far, the corresponding heating priority is determined for any area in the above manner, and subsequently the heating gas resources can be centrally allocated based on the size of the heating priority number.

[0053] S105, supplying heat to each area in turn according to the heating priority number and heating demand of each area.

[0054] Specifically, in the embodiment of the present invention, different heating strategies can be adopted for areas with different priorities. Among them, as an optional embodiment of the present invention, heating each area in turn according to the heating priority number and heating demand of each area includes: firstly transporting gas to the main pipeline of the area with a high heating priority number, and supplying heat to users in the area in turn based on the heating demand of the area with a high heating priority number; after the heating demand of the area with a high heating priority number is met, the remaining gas is allocated to the area with the next heating priority.

[0055] Among them, for high-priority areas, since most of its users are residents and have a large gas demand, the gas source can be preferentially transported to the main pipeline corresponding to this area, and then transported to the main pipelines of other areas. At the same time, when the gas demand in this area is met, the remaining gas will be redistributed to other areas with relatively lower priorities, thereby coordinating the gas demand in different regions for resource regulation. This reduces operating costs and enhances user satisfaction and system stability.

[0056] The embodiment of the present invention can divide the gas consumption of users in different regions into multiple gas consumption sequences and determine the corresponding gradients. Then, the heating priority number of the region is determined according to the gas consumption of users corresponding to the gas consumption sequences of each gradient in the region, and finally, heating is provided to each region in a targeted manner according to the heating priority number and heating demand. In this way, the heating demand changes of users in different regions are timely adjusted in a targeted manner, thereby improving the room temperature stability and heating flexibility.
