Description

Technical Field

[0001] This invention relates to the field of power load control technology, specifically to a method and system for extending the power load control terminal circuit of a dedicated transformer customer. Background Technology

[0002] With economic development and increasing social electricity demand, especially the growing electricity load of dedicated transformer customers in industries and commerce, the stability and reliability of the power system are facing increasingly severe challenges. Against this backdrop, traditional power load control methods are gradually revealing many shortcomings, particularly in environments with a large number of load switches and frequent changes in load demand. The response speed and flexibility of a single control method are far from meeting the needs of modern power systems.

[0003] Currently, the use of dual-energy controllers for the orderly control of load switches enables the management of the power load control terminal circuits of sixteen load switches through four rounds of control. However, traditional dual-energy controller systems still have certain limitations when facing complex and dynamic load changes. First, existing control systems typically rely on central dispatch and control, making it difficult for the system to react quickly when load demand fluctuates significantly or power load is uneven. Second, single control methods are prone to system overload or response lag, especially in environments with a large number of devices and frequent changes in load demand; the system's flexibility and adaptability cannot meet the demands of modern power systems for efficient and intelligent control. Summary of the Invention

[0004] The purpose of this invention is to provide a method and system for extending the circuit of the power load control terminal of a dedicated transformer customer, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A method for extending the circuit of a dedicated transformer customer power load control terminal includes the following steps:

[0007] Step S100. Collect historical power data of dedicated transformer customers. Based on the historical power data of dedicated transformer customers, simulate the orderly control process of load switching using a dual energy controller and obtain the simulated load data of each power load control terminal circuit. Analyze the simulated load data to obtain the comprehensive load demand index of each power load control terminal circuit.

[0008] Step S200. Combine the comprehensive load demand index of each power load control terminal loop to evaluate the response priority of each power load control terminal loop; and based on the evaluation results of the response priority, configure the corresponding initial scheduling strategy for each power load control terminal loop.

[0009] Step S300. Based on the initial scheduling strategy, the real-time load data of each power load control terminal loop is collected using the dual energy controller, the real-time load data is analyzed to obtain the real-time load characteristics of each power load control terminal loop; the deviation relationship between the real-time load characteristics and the corresponding load demand characteristics is analyzed to obtain the matching degree between the actual load and the target load.

[0010] Step S400. Based on the matching degree between the actual load and the target load, determine whether the response priority of each power load control terminal loop needs to be adjusted; adjust the response priority of the power load control terminal loops that need adjustment, and update the corresponding initial scheduling strategy in real time based on the adjustment results, thereby obtaining the real-time scheduling strategy.

[0011] Furthermore, step S100 includes:

[0012] S101. Collect historical power data from dedicated transformer customers, and based on this data, generate simulated tripping and closing sequences for each power load control terminal circuit on the simulation platform using dual-energy controller logic, and record the corresponding simulated load data. For each power load control terminal circuit, smooth the simulated load data using a sliding window mean filter. Analyze the processed simulated load data to extract corresponding load demand characteristics and construct a load demand feature vector Fi, where Fi = [ΔPi, σi, Ti], where Fi represents the load demand feature vector of the i-th power load control terminal circuit, ΔPi represents the load peak-valley difference of the i-th power load control terminal circuit, σi represents the load volatility of the i-th power load control terminal circuit, and Ti represents the electricity consumption period of the i-th power load control terminal circuit. The formula for calculating the load peak-valley difference is: ΔPi = max(Pi) - min(Pi), where max(Pi) represents the maximum load value of the i-th power load control terminal circuit, and min(Pi) represents the minimum load value of the i-th power load control terminal circuit. The formula for calculating the load volatility is: N represents the total number of time points of the load data of the i-th power load control terminal loop, Pi(t) represents the actual power value of the load data of the i-th power load control terminal loop at time t, and Pμ_i represents the average power value of the load data of the i-th power load control terminal loop.

[0013] S102. For each feature value in the load demand feature vector of each power load control terminal circuit, perform standardization processing and calculate the information entropy Ej of the corresponding feature value. The corresponding calculation formula is as follows: Where n represents the number of power load control terminal circuits, p ijThis represents the probability distribution of the standardized feature values; the weight wj of each feature value is calculated based on the information entropy, and... Where k is the total number of features in the load demand feature vector, and m represents the index of the feature; the comprehensive load demand index Di for each power load control terminal loop is calculated based on the feature weights and standardized feature values, and , where Di represents the comprehensive load demand index of the i-th power load control terminal loop, and xij represents the j-th standardized feature value in the load demand feature vector of the i-th power load control terminal loop.

[0014] Furthermore, step S200 includes:

[0015] S201. For each power load control terminal loop, obtain the corresponding comprehensive load demand index, evaluate the response priority of each power load control terminal loop, and the evaluation formula for the response priority is as follows: Si = f(Di), where Si represents the response priority score of the i-th power load control terminal loop, and f(Di) represents the priority function evaluated based on the comprehensive load demand index Di of the corresponding power load control terminal loop; the specific priority function can be linear, exponential, or other forms. Generally, the larger the comprehensive load demand index, the higher the response priority. For example, the power load control terminal loop can be calculated according to the following formula. The response priority score is obtained by calculating the proportion of the comprehensive load demand index of the i-th power load control terminal loop in the comprehensive load demand index of all power load control terminal loops.

[0016] S202. Based on the response priority score Si, arrange the power load control terminal circuits in descending order, group them according to the dual-energy controller round capacity, and specify the round sequence number. Where N(Si) represents the ranking number corresponding to the response priority score Si; according to the round number L, a round-loop mapping table is constructed, and the corresponding initial scheduling strategy is configured based on the round-loop mapping table.

[0017] Furthermore, step S300 includes:

[0018] S301. Based on the initial scheduling strategy, real-time load data of each power load control terminal loop is collected using a dual-energy controller. The real-time load data is analyzed according to the analysis process of simulated load data to extract the real-time load feature vector Fr_i=[ΔPr_i,σr_i,Tr_i]. The deviation between the real-time load feature vector and the load demand feature vector of each power load control terminal loop is calculated, and the corresponding calculation formula is as follows: Where Ri represents the deviation between the real-time load feature vector and the load demand feature vector of the i-th power load control terminal loop, Fr_ij represents the j-th feature value in the real-time load feature vector of the i-th power load control terminal loop, and Fij represents the j-th feature value in the load demand feature vector of the i-th power load control terminal loop.

[0019] S302. Calculate the similarity between the real-time load feature vector and the load demand feature vector of each power load control terminal loop, denoted as: Sim(Fr_i,Fi); combine the deviation between the real-time load feature vector and the load demand feature vector of each power load control terminal loop to calculate the matching degree between the actual load and the target load, calculated as: Mi=α·Sim(Fr_i,Fi)+(1-α)·e -β·Ri , where α and β represent regulation factors.

[0020] Furthermore, step S400 includes:

[0021] S401. Obtain the matching degree between the actual load and the target load of each power load control terminal loop, compare the matching degree with a preset threshold, and determine whether the response priority of the corresponding power load control terminal loop needs to be adjusted; if the matching degree is greater than or equal to the preset threshold, the response priority of the corresponding power load control terminal loop does not need to be adjusted; if the matching degree is less than the preset threshold, the response priority of the corresponding power load control terminal loop needs to be adjusted.

[0022] S402. For the power load control terminal loop that needs to adjust the response priority, calculate the corresponding deviation proportional coefficient H, and the corresponding calculation formula is: H=γ×(Mi / M0), where γ represents the adjustment parameter and M0 represents the preset threshold; combined with the deviation proportional coefficient, calculate the adjusted response priority score Si'=Si×(1+H), where the value of H is determined by the adjustment parameter γ; reorder according to the adjusted response priority score, generate a real-time round-loop mapping table, and update the corresponding initial scheduling strategy in real time according to the real-time round-loop mapping table to obtain the real-time scheduling strategy.

[0024] The historical data acquisition and simulation analysis module collects historical power data from dedicated transformer customers. Based on this data, it simulates the orderly control process of load switches using a dual-energy controller and obtains simulated load data for each power load control terminal circuit. The module then analyzes the simulated load data to obtain the comprehensive load demand index for each power load control terminal circuit.

[0027] The response priority adjustment and real-time scheduling strategy update module determines whether the response priority of each power load control terminal loop needs to be adjusted based on the matching degree between the actual load and the target load; it adjusts the response priority of the power load control terminal loops that need adjustment, and updates the corresponding initial scheduling strategy in real time based on the adjustment results, thereby obtaining the real-time scheduling strategy.

[0028] Furthermore, the historical data acquisition and simulation analysis module includes a historical data acquisition unit and a simulation analysis unit;

[0029] The historical data acquisition unit is used to collect historical power data of dedicated transformer customers; the simulation analysis unit simulates the orderly control process of load switching using a dual-energy controller based on the historical power data of dedicated transformer customers, and obtains the simulated load data of each power load control terminal circuit; the simulated load data is analyzed to obtain the comprehensive load demand index of each power load control terminal circuit.

[0030] Furthermore, the load demand assessment and scheduling strategy generation module includes a load demand assessment unit and a scheduling strategy generation unit;

[0031] The load demand assessment unit evaluates the response priority of each power load control terminal loop by combining the comprehensive load demand index of each power load control terminal loop; the scheduling strategy generation unit configures the corresponding initial scheduling strategy for each power load control terminal loop based on the evaluation results of the response priority.

[0032] Furthermore, the real-time load data acquisition and load characteristic analysis module includes a real-time load data acquisition unit and a load characteristic analysis unit;

[0033] The real-time load data acquisition unit, based on the initial scheduling strategy, uses the dual energy controller to collect real-time load data from each power load control terminal circuit. The load characteristic analysis unit analyzes the real-time load data to obtain the real-time load characteristics of each power load control terminal circuit. It analyzes the deviation relationship between the real-time load characteristics and the corresponding load demand characteristics to obtain the matching degree between the actual load and the target load.

[0034] Furthermore, the response priority adjustment and real-time scheduling strategy update module includes a response priority adjustment unit and a real-time scheduling strategy update unit;

[0035] The response priority adjustment unit determines whether the response priority of each power load control terminal loop needs to be adjusted based on the matching degree between the actual load and the target load. The real-time scheduling strategy update unit adjusts the response priority of the power load control terminal loops that need adjustment and updates the corresponding initial scheduling strategy in real time based on the adjustment results, thereby obtaining the real-time scheduling strategy.

[0036] Compared with existing technologies, the beneficial effects of this invention are as follows: By introducing real-time scheduling strategy updates, this invention can dynamically adjust the response priority of each power load control terminal loop; when the load changes rapidly, the system can respond quickly, avoiding the response lag problem under the central dispatching method. This invention combines historical power data and real-time load data, utilizes a simulation platform to generate load demand characteristics of power load control terminal loops, and optimizes response priorities based on these characteristics; compared with traditional methods, this invention, based on technologies such as comprehensive load demand index, eigenvalue standardization, and information entropy, can more accurately assess load demand, thereby achieving more scientific and reasonable load scheduling and avoiding overload or response lag problems in traditional systems. This invention introduces a load matching degree and threshold comparison mechanism; when the matching degree is lower than a preset threshold, it can automatically adjust the response priority of the power load control terminal loop and regenerate the real-time round-loop mapping table based on this adjustment; compared with the fixed priority in traditional methods, this invention significantly improves the system's ability to cope with sudden load fluctuations by updating priorities in real time. This invention generates a real-time round-loop mapping table based on the adjusted priority score and updates the scheduling strategy in real time based on this. Compared to the limitations of static scheduling strategies in existing technologies, this invention can flexibly adjust the scheduling strategy according to real-time load changes, optimizing system operating efficiency. This invention manages the power load control terminal circuit through a four-round control process, combining real-time load data and load demand characteristic analysis to effectively reduce system overload risk and improve resource utilization efficiency. Traditional dual-energy controllers typically rely on fixed round control strategies, which are prone to scheduling delays when load demand changes significantly. This invention, however, achieves more efficient load management by adjusting the rounds and priorities. Attached Figure Description

[0054] A method for extending the circuit of a dedicated transformer customer power load control terminal includes the following steps:

[0055] Step S100. Collect historical power data of dedicated transformer customers. Based on the historical power data of dedicated transformer customers, simulate the orderly control process of load switching using a dual energy controller and obtain the simulated load data of each power load control terminal circuit. Analyze the simulated load data to obtain the comprehensive load demand index of each power load control terminal circuit.

[0056] Step S200. Combine the comprehensive load demand index of each power load control terminal loop to evaluate the response priority of each power load control terminal loop; and based on the evaluation results of the response priority, configure the corresponding initial scheduling strategy for each power load control terminal loop.

[0057] Step S300. Based on the initial scheduling strategy, the real-time load data of each power load control terminal loop is collected using the dual energy controller, the real-time load data is analyzed to obtain the real-time load characteristics of each power load control terminal loop; the deviation relationship between the real-time load characteristics and the corresponding load demand characteristics is analyzed to obtain the matching degree between the actual load and the target load.

[0058] Step S400. Based on the matching degree between the actual load and the target load, determine whether the response priority of each power load control terminal loop needs to be adjusted; adjust the response priority of the power load control terminal loops that need adjustment, and update the corresponding initial scheduling strategy in real time based on the adjustment results, thereby obtaining the real-time scheduling strategy.

[0059] Step S100 includes:

[0060] S101. Collect historical power data from dedicated transformer customers, and based on this data, generate simulated tripping and closing sequences for each power load control terminal circuit on the simulation platform using dual-energy controller logic, and record the corresponding simulated load data. For each power load control terminal circuit, smooth the simulated load data using a sliding window mean filter. Analyze the processed simulated load data to extract corresponding load demand characteristics and construct a load demand feature vector Fi, where Fi = [ΔPi, σi, Ti], where Fi represents the load demand feature vector of the i-th power load control terminal circuit, ΔPi represents the load peak-valley difference of the i-th power load control terminal circuit, σi represents the load volatility of the i-th power load control terminal circuit, and Ti represents the electricity consumption period of the i-th power load control terminal circuit. The formula for calculating the load peak-valley difference is: ΔPi = max(Pi) - min(Pi), where max(Pi) represents the maximum load value of the i-th power load control terminal circuit, and min(Pi) represents the minimum load value of the i-th power load control terminal circuit. The formula for calculating the load volatility is: N represents the total number of time points of the load data of the i-th power load control terminal loop, Pi(t) represents the actual power value of the load data of the i-th power load control terminal loop at time t, and Pμ_i represents the average power value of the load data of the i-th power load control terminal loop.

[0061] S102. For each feature value in the load demand feature vector of each power load control terminal circuit, perform standardization processing and calculate the information entropy Ej of the corresponding feature value. The corresponding calculation formula is as follows: Where n represents the number of power load control terminal circuits, p ijThis represents the probability distribution of the standardized feature values; the weight wj of each feature value is calculated based on the information entropy, and... Where k is the total number of features in the load demand feature vector, and m represents the index of the feature; the comprehensive load demand index Di for each power load control terminal loop is calculated based on the feature weights and standardized feature values, and , where Di represents the comprehensive load demand index of the i-th power load control terminal loop, and xij represents the j-th standardized feature value in the load demand feature vector of the i-th power load control terminal loop.

[0062] Step S200 includes:

[0063] S201. For each power load control terminal loop, obtain the corresponding comprehensive load demand index, evaluate the response priority of each power load control terminal loop, and the evaluation formula for the response priority is as follows: Si = f(Di), where Si represents the response priority score of the i-th power load control terminal loop, and f(Di) represents the priority function evaluated based on the comprehensive load demand index Di of the corresponding power load control terminal loop; the specific priority function can be linear, exponential, or other forms. Generally, the larger the comprehensive load demand index, the higher the response priority. For example, the power load control terminal loop can be calculated according to the following formula. The response priority score is obtained by calculating the proportion of the comprehensive load demand index of the i-th power load control terminal loop in the comprehensive load demand index of all power load control terminal loops.

[0064] S202. Based on the response priority score Si, arrange the power load control terminal circuits in descending order, group them according to the dual-energy controller round capacity, and specify the round sequence number. Where N(Si) represents the ranking number corresponding to the response priority score Si; according to the round number L, a round-loop mapping table is constructed, and the corresponding initial scheduling strategy is configured based on the round-loop mapping table.

[0065] In this embodiment, assuming there are a total of n loops, and n=16, there will be 16 / 4=4 rounds, with each round containing 4 loops. Rounds are allocated according to the loops' priority from highest to lowest. For example, if a loop's response priority score ranking number is 1, then the round number... Therefore, the round number of this loop is 1. According to the round number L, loops with the same round number are grouped together, and different loops with the same round number are sorted according to the response priority score, thus forming a round-loop mapping table.

[0066] For each loop, an initial scheduling strategy is configured based on its position and priority score in the round-loop mapping table. The specific steps are as follows:

[0067] For high-priority loops (loops with round number 1):

[0068] These loops typically have the most pressing load demands and the greatest impact on system stability, therefore they need to be prioritized. Scheduling strategies may include:

[0069] Do not reduce load: Prioritize ensuring the load demand of these circuits and avoid reducing their load.

[0070] Activate backup power: Based on the system load, activate backup power to ensure that the power needs of these circuits are met;

[0071] Real-time adjustment: Monitor load fluctuations and make adjustments in real time to avoid power shortages caused by load surges.

[0072] For medium priority loops (loops with round number 2):

[0073] These circuits have high load demands but low response priority. Therefore, it is necessary to meet their power demands as much as possible while ensuring overall system stability. Dispatch strategies may include:

[0074] Appropriate load reduction: Based on real-time load demand, appropriately reduce the load on these circuits to ensure stable operation as much as possible;

[0075] Allocate remaining capacity: Based on the current remaining power capacity of the system, allocate it appropriately to these circuits to ensure that their critical loads are supported;

[0076] Backup power supply activation conditions: When the load approaches the threshold, the backup power supply is activated to cope with load fluctuations.

[0077] For low-priority loops (loops with round number 3 or below)

[0078] These circuits have low load requirements and low priority. To avoid excessive resource consumption, their scheduling strategies typically include:

[0079] Significant load reduction: For these loops, a significant load reduction can be implemented based on the overall system load conditions, especially when load demand is too high.

[0080] Off-peak operation: These circuits can be scheduled to operate during off-peak hours or during periods of low load demand to reduce power consumption;

[0081] Delayed activation of backup power: For these circuits, backup power is only activated under abnormal circumstances to avoid unnecessary waste of resources.

[0082] Step S300 includes:

[0083] S301. Based on the initial scheduling strategy, real-time load data of each power load control terminal loop is collected using a dual-energy controller. The real-time load data is analyzed according to the analysis process of simulated load data to extract the real-time load feature vector Fr_i=[ΔPr_i,σr_i,Tr_i]. The deviation between the real-time load feature vector and the load demand feature vector of each power load control terminal loop is calculated, and the corresponding calculation formula is as follows: Where Ri represents the deviation between the real-time load feature vector and the load demand feature vector of the i-th power load control terminal loop, Fr_ij represents the j-th feature value in the real-time load feature vector of the i-th power load control terminal loop, and Fij represents the j-th feature value in the load demand feature vector of the i-th power load control terminal loop.

[0084] S302. Calculate the similarity between the real-time load feature vector and the load demand feature vector of each power load control terminal loop, denoted as: Sim(Fr_i,Fi); combine the deviation between the real-time load feature vector and the load demand feature vector of each power load control terminal loop to calculate the matching degree between the actual load and the target load, calculated as: Mi=α·Sim(Fr_i,Fi)+(1-α)·e -β·Ri , where α and β represent regulation factors.

[0085] Step S400 includes:

[0086] S401. Obtain the matching degree between the actual load and the target load of each power load control terminal loop, compare the matching degree with a preset threshold, and determine whether the response priority of the corresponding power load control terminal loop needs to be adjusted; if the matching degree is greater than or equal to the preset threshold, the response priority of the corresponding power load control terminal loop does not need to be adjusted; if the matching degree is less than the preset threshold, the response priority of the corresponding power load control terminal loop needs to be adjusted.

[0087] S402. For the power load control terminal loop that needs to adjust the response priority, calculate the corresponding deviation proportional coefficient H, and the corresponding calculation formula is: H=γ×(Mi / M0), where γ represents the adjustment parameter and M0 represents the preset threshold; combined with the deviation proportional coefficient, calculate the adjusted response priority score Si'=Si×(1+H), where the value of H is determined by the adjustment parameter γ; reorder according to the adjusted response priority score, generate a real-time round-loop mapping table, and update the corresponding initial scheduling strategy in real time according to the real-time round-loop mapping table to obtain the real-time scheduling strategy.
