[0008] According to the above technical solution, the supply end includes n levels of supply units; each level of supply unit includes an energy supply system;

[0009] Where n represents the number of supply units in the supply end, n≥2;

[0010] The energy supply system on the demand side is various power supply systems.

[0011] According to the above technical solution, the interaction management module includes a data processing unit, a data analysis unit and a control unit;

[0012] The data processing unit is used to receive and process current energy information data, correct erroneous data, and ensure data accuracy;

[0013] The data analysis unit is used to analyze the current energy information data according to the historical big data in the database, and store the analyzed current energy information data in the database;

[0014] The control unit is used to control the supply end to supply the demand end according to the analysis data.

[0015] A multi-source data interaction management method based on big data, the method comprising the following steps:

[0016] S10, the demand side generates energy demand, and the supply side supplies the demand side;

[0017] S20, collecting real-time energy demand data of users on the demand side, and cleaning and processing the energy demand data;

[0018] S30, collecting real-time energy information data supplied by the supply side;

[0019] S40, analyzing the data collected in step S20 and the historical big data in the database to predict the total energy demand at the demand side at the next moment;

[0020] S50, analyzing the real-time energy supply information data collected in step S30, the energy demand forecast data in step S40 and the historical big data in the database, and intelligently coordinating the energy supply on the supply side;

[0021] S60, sending the analyzed data to a database for storage;

[0022] Among them, the current energy information data includes the energy demand information data sent by the current demand side and the energy supply information data sent by the current supply side; the historical big data includes the historical energy demand information big data from the demand side and the historical energy supply information big data from the supply side.

[0023] In step S20, when the demand side is connected to multiple energy demand devices, there will be a lot of collected data in the demand side. Therefore, there is often a risk of transmission error in the transmission of the collected data. In order to eliminate abnormal values ​​in the collected data and protect the integrity of the data, the energy demand data needs to be cleaned and processed. The method steps are as follows:

[0024] S101, analyzing energy demand data to obtain a real-time energy demand set A(t) at the demand side; wherein A(t) = {a1(t), a2(t), a3(t), ..., a n (t)}; a1(t), a2(t), a3(t),..., a n (t) represents the energy demand of each data point on the demand side at time t;

[0025] S102, using the isolation forest algorithm, using the demand-side real-time energy demand set A(t) to train the isolation forest model, and calculating the abnormal score of each data point in the energy demand data set, recorded as set B(t); where B(t) = {b1(t), b2(t), b3(t), ..., b n (t)}; b1(t), b2(t), b3(t),..., b n (t) represents the abnormal score of each data point in the energy demand data at time t;

[0026] The isolation forest algorithm can accurately find outliers in energy collection data without being affected by imbalanced data distribution;

[0027] S103, set a threshold K, compare the abnormal score of each data point in the collection B(t) with K, and determine whether each data point in A(t) is abnormal; when b i (t)≥K, then it corresponds to b i The energy demand data point in (t) is abnormal; when b i When (t)<K, it corresponds to b i The energy demand data point in (t) is normal;

[0028] S104, correcting abnormal data in A(t);

[0029] Among them, K represents the threshold when the energy demand data is abnormal, which is obtained by the anomaly score of the known abnormal data in the database; n represents the number of data points on the demand side.

[0030] When the data points in A(t) are abnormal, the steps for correcting the abnormal data points are as follows:

[0031] S201, determine the abnormal data point a in A(t) i (t);

[0032] S202, according to a in the database i (t) historical big data information, taking a i (t) The first m items of data a i (t-1), a i (t-2), a i (t-3), ..., a i (tm), establish the independent variable as t and the dependent variable as a i The univariate multiple linear regression model is expressed as:

[0033] a i =β0+β1t+β2t 2 +...+β m t m +ε;

[0034] Among them, β0, β1, β2,..., β m is the regression coefficient; ε is the error term;

[0035] S203, substituting the time t corresponding to the abnormal data point into the regression model of step S202, and the obtained value is the corrected abnormal data;

[0036] Among them, m represents the corresponding a taken from the database i (t) The number of historical big data;

[0037] In order to correct the abnormal data in time and not affect the energy supply efficiency of the supply side to the demand side, only the historical data before the abnormal data is used as the basis for correction. The abnormal data is corrected by establishing a univariate multiple linear regression model.

[0038] In step S40, the total energy demand X is obtained through the real-time energy demand data of the user at the demand end. t ; Based on the historical demand-side energy demand data and the current demand-side energy demand data in the database, the LSTM algorithm is used to predict the demand-side energy demand Y at the next moment t ;

[0039] The LSTM algorithm is used to predict the total energy demand at the next moment based on the change cycle of the total energy demand on the demand side in historical data, so that the management system that has long relied on big data has a learning mechanism and improves the reliability of the prediction.

[0040] The supply end includes n levels of supply units; when the current supply unit cannot meet the energy demand of the demand end, the next level of supply unit is controlled to join the demand end supply;

[0041] Wherein, n represents the number of supply unit levels in the supply end, n≥2.

[0042] In the process of energy supply of some systems, multiple supply systems are often used, and the maximum energy supply per unit time of each supply system is limited. When the demand side is at its peak, the lack of coordination between different supply units may lead to unstable supply. Therefore, the supply units are adjusted in advance by means of advance prediction. The method steps for intelligent coordination of energy supply on the supply side are as follows:

[0043] S301, analyzing the historical big data in the database to obtain the maximum supply per unit time of the energy supply system corresponding to each level of supply unit k1, k2, ..., k n ; Set the supply interval of each level supply unit to be

[0044] Among them, k i represents the maximum supply per unit time of the energy supply system corresponding to the i-th supply unit;

[0045] S302: Based on the predicted total energy demand Y at the next moment t Determine the number of supply units at the supply end at the next moment, w, when Y t When the interval threshold is reached, the next level supply unit is started in advance;

[0046] S303, analyzing the real-time energy supply information data of the supply side to obtain the energy supply amount z1(t), z2(t), ..., z1(t) of the energy supply system in each level of supply unit at the current moment. n (t);

[0047] Among them, z i (t) represents the energy supply amount of the energy supply system corresponding to the i-th supply unit at the current moment;

[0048] S304, z i (t) and k i For comparison; when z i (t)<k i When k is controlled, the energy supply of the i+1th level supply unit is i -z i (t) The supply is handed over to the i-th level supply unit; in order to prevent inaccurate prediction data and improve system stability, the supply unit is closed only when the i+1-th level supply unit has no supply task;

[0049] Because z i (t)≥k i The situation has been predicted in advance by step S302, so only z needs to be considered i (t)<k i situation.

[0050] Since the maximum energy supply per unit time of the energy supply system will be affected by factors such as system equipment aging and system autonomous update, it is necessary to i Continuously update to ensure the accuracy of intelligent regulation of the energy system, so the maximum energy supply per unit time of the energy supply system corresponding to each level of supply unit is k i It will change with the maximum energy supply per unit time data during the period when the supply system is at its maximum working efficiency; among them, the calculated k i The method steps are:

[0051] S401, setting the time period when the energy supply system in each level of supply unit is at maximum working efficiency as a cycle;

[0052] S402, when the number of supply units at the supply end is w≥2, record the maximum energy supply data per unit time of each energy supply system corresponding to the supply unit in the w-1-level supply unit within the cycle;

[0053] S403. When the cycle ends, the sliding average method is used to process the cycle data, and then the average value method is used to calculate the maximum energy supply data per unit time in the cycle after processing. The average value obtained is the k after the change. i ;

[0054] Since the number of supply units on the supply side w≥2, the corresponding energy supply systems in the w-1 level supply units are at maximum working efficiency. By using the sliding average method and the average method, the system threshold k is effectively predicted. i The changes improve the stability of the system.

[0055] Compared with the prior art, the beneficial effects achieved by the present invention are: providing a multi-source data interaction management system and method based on big data, collecting and cleaning the electricity consumption data of demand-side users, eliminating abnormal values, and enhancing the accuracy of data analysis and prediction and the stability of system power supply; integrating big data from different sources in the power system, analyzing the data information hidden in the big data, improving the learning ability of the power system, and optimizing the real-time control of electricity by the power system.

Set the supply intervals of each level supply unit to [0, k1), [k1, k1+k2), ..., Among them, k i represents the maximum supply per unit time of the energy supply system corresponding to the i-th supply unit; S302: Based on the predicted total energy demand Y at the next moment t Determine the number of supply units at the supply end at the next moment, w, when Y t When the interval threshold is reached, the next level supply unit is started in advance; S303, analyzing the real-time energy supply information data of the supply side to obtain the energy supply amount z1(t), z2(t), ..., z1(t) of the energy supply system in each level of supply unit at the current moment. n (t); Among them, z i (t) represents the energy supply amount of the energy supply system corresponding to the i-th supply unit at the current moment; S304, z i (t) and k i For comparison; when z i (t)<k i When the energy supply of the i+1th level supply unit is controlled, i -z i (t) The supply is handed over to the i-th level supply unit; when the i+1-th level supply unit has no supply task, the supply unit is turned off; The maximum energy supply per unit time of the energy supply system corresponding to each level of supply unit k i It will change with the maximum energy supply per unit time data during the period when the supply system is at its maximum working efficiency; among them, the calculated k i The method steps are: S401, setting the time period when the energy supply system in each level of supply unit is at maximum working efficiency as a cycle; S402, when the number of supply units at the supply end is w≥2, record the maximum energy supply data per unit time of each energy supply system corresponding to the supply unit in the w-1-level supply unit within the cycle; S403. When the cycle ends, the sliding average method is used to process the cycle data, and then the average value method is used to calculate the maximum energy supply data per unit time in the cycle after processing. The average value obtained is the k after the change. i .
