[0020] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application, and are not used to limit the present application.

[0021] In order to better understand the technical solutions of the present application, the detailed description will be made with reference to the drawings and specific embodiments of the present application.

[0022] The main solution of the embodiment of the present application is: the distributed power intelligent regulation system includes a cloud master station, a transformer area terminal and a plurality of flexible regulation devices, the transformer area terminal and the cloud master station perform data interaction, the transformer area terminal is connected with the flexible regulation devices respectively, and the distributed power intelligent regulation method of the transformer area terminal is applied to the transformer area terminal. The distributed power intelligent regulation method of the transformer area terminal includes: obtaining the total regulation index issued by the cloud master station; decomposing the total regulation index to obtain the decomposed regulation index; distributing the decomposed regulation index to the corresponding flexible regulation device respectively, and completing the regulation.

[0023] Because the existing technology involves the cloud master station directly controlling each distribution area in a unified manner, there are problems such as low control accuracy, slow response speed, insufficient flexibility, and low system reliability.

[0024] This application provides a solution that decomposes control indicators and executes them efficiently through terminals, achieving group control and dispatch to improve the automation level and overall operational efficiency of the power system and ensure the safe and stable operation of the power grid. Control indicators are allocated to terminals through a master station, and the terminals proportionally control the active power of flexible users according to preset strategies. When the actual controlled power reaches or exceeds the indicator, control automatically stops, thereby achieving efficient and precise group control and dispatch, improving the automation level and operational efficiency of the power system, and ensuring the safe and stable operation of the power grid.

[0025] It should be noted that the executing entity in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, or mobile phone, or an electronic device capable of performing the above functions, such as a distributed power intelligent control device in a distribution area terminal. The following description uses a distributed power intelligent control device in a distribution area terminal as an example to illustrate this embodiment and the subsequent embodiments.

[0026] Based on this, embodiments of this application provide a method for intelligent control of distributed power supply in a distribution terminal, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the distributed power intelligent control method for the transformer terminal of this application.

[0027] In this embodiment, the distributed power intelligent control method for the transformer terminal includes steps S10~S30: Step S10: Obtain the overall control indicators issued by the cloud master station.

[0028] like Figure 2 As shown, Figure 2 This is a schematic diagram of the architecture between the distribution area terminal, the cloud master station, and the flexible control equipment. Specifically, the distributed power intelligent control system includes a cloud master station, distribution area terminals, and multiple flexible control devices. The distribution area terminals interact with the cloud master station, and each distribution area terminal is connected to one of the flexible control devices. The distribution area terminals receive the total control indicators issued by the cloud master station through a communication module. These total control indicators are formulated based on the overall operation status and control needs of the power grid and are used to indicate the total amount of active power adjustment that the distribution area needs to make.

[0029] It should be noted that with the rapid development of low-voltage distributed photovoltaic, the existing cloud master station directly regulates and controls a large number of transformer areas, but lacks detailed understanding of the specific load conditions of the transformer areas, resulting in low regulation accuracy and difficulty in realizing fine management. Therefore, the cloud master station and the transformer area terminal are communicatively connected in the embodiment, and data interaction can be performed.

[0030] The total regulation index is a grid regulation index, and the grid regulation index can be a total peak regulation index of a region or a line. After receiving the grid regulation index, the cloud master station sends the total regulation index to the transformer area terminal.

[0031] Step S20: decompose the total regulation index to obtain a decomposed regulation index.

[0032] It should be noted that after receiving the total regulation index, the regulation module of the transformer area terminal will decompose the total regulation index into a plurality of decomposed regulation indexes according to a preset decomposition strategy and in combination with information such as the total controllable load of the users participating in flexible regulation. The decomposed regulation index is the regulation index of each transformer area.

[0033] It should be noted that the embodiment only decomposes the users participating in flexible regulation in the transformer area, and the following non-regulation conditions are excluded in advance before decomposition: user equipment offline, user has reported stop or other faults or uncontrollable state.

[0034] Step S30: distribute the decomposed regulation index to the corresponding flexible regulation device to complete the regulation.

[0035] In a specific implementation, after obtaining the decomposed regulation index, the distribution module of the transformer area terminal sends the index to the corresponding flexible regulation device.

[0036] Meanwhile, to improve the effect of regulation, the transformer area terminal can be uniformly provided with a percentage of active power adjustment when distributing. Specifically, the percentage of active power adjustment is determined comprehensively according to the controllable load of the device, the total controllable load and the decomposed regulation index. Through such a setting, each flexible regulation device can adjust the power according to the established proportion, thereby realizing the accuracy and efficiency of overall regulation.

[0037] The embodiment provides a distributed power intelligent regulation method of a transformer area terminal. The transformer area terminal is connected with a plurality of flexible regulation devices and a cloud master station. The method comprises the following steps: obtaining a total regulation index sent by the cloud master station; decomposing the total regulation index to obtain a decomposed regulation index; distributing the decomposed regulation index to the corresponding flexible regulation device to complete the regulation. The regulation index is distributed to the transformer area terminal by the cloud master station. The terminal decomposes the total regulation index according to the strategy, and regulates the decomposed index, thereby realizing efficient and accurate group regulation and control, improving the automation level and operation efficiency of the power system, and ensuring the safe and stable operation of the grid.

[0038] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as the above embodiment one can refer to the above introduction, and the subsequent will not be described in detail. On this basis, please refer to Figure 3 , step S20 includes steps S201-S202: Step S201: obtaining the total controllable load of the users participating in flexible regulation.

[0039] It should be noted that the total controllable load of the users participating in flexible regulation is the total load prediction value of all users participating in flexible regulation under the transformer area. Specifically, the real-time load data and historical load curve of the users participating in regulation can be collected to predict the total load in the regulation period, for example, the load prediction value in the next 1 hour.

[0040] In actual calculation, the load of offline, stop reporting and other users can be excluded from the total load prediction value to obtain the total controllable load that can actually participate in regulation.

[0041] Step S202: decomposing the total regulation index according to the total controllable load to obtain a decomposed regulation index.

[0042] In specific implementation, the total controllable load can be decomposed according to the total regulation index using a specific decomposition strategy, thereby obtaining a decomposed regulation index. The decomposition strategy can be an equal proportion decomposition strategy, a decomposition strategy based on load proportion or other optimization decomposition strategy. Taking the equal proportion decomposition strategy as an example, the total regulation index is decomposed to each user in equal proportion according to the proportion of the controllable load of each user participating in flexible regulation in the total controllable load, and then the decomposed regulation index corresponding to each user is obtained. This decomposition method can ensure the fairness and rationality of regulation, and avoid some users bearing too much or too little regulation task.

[0043] In actual application, the selection of the decomposition strategy should be determined according to the specific regulation demand and the characteristics of the transformer area. For example, in the transformer area with relatively uniform load distribution, the equal proportion decomposition strategy can be more appropriate; while in the transformer area with uneven load distribution or special regulation demand, a more complex decomposition strategy, such as the decomposition strategy based on load proportion or other optimization decomposition strategy, can be used to achieve more accurate regulation.

[0044] In a feasible implementation manner, step S202 can include steps A11-A14: Step A11: obtaining a preset redundancy coefficient; It should be noted that the preset redundancy coefficient can be configured in advance, for example, the preset redundancy coefficient is selected from 100%-120%, and the default 105% is taken as an example for description in the embodiment.

[0045] By introducing a redundancy coefficient in the decomposition of the control index, it is ensured that the control target can still be completed in the case that part of the equipment or users are uncontrollable.

[0046] Step A12: calculating an updated control index according to the preset redundancy coefficient and the total control index; In a specific implementation, the updated control index can be calculated according to the preset redundancy coefficient and the total control index, and the updated control index is calculated as follows: Updated control index = total control index x preset redundancy coefficient For example, if the total control index is 1000kW and the redundancy coefficient is 105%, the updated control index is 1050kW.

[0047] Step A13: calculating the controllable load proportion of the transformer area according to the total controllable load; It should be noted that when the index is decomposed, the control index needs to be allocated according to the proportion of the controllable load of each transformer area in the total controllable load, and therefore the controllable load proportion of the transformer area can be calculated by the total controllable load.

[0048] Specifically, the controllable load proportion of the transformer area is calculated as follows:

[0049] Step A14: determining the decomposed down-regulation index according to the updated control index and the controllable load proportion.

[0050] It should be noted that the decomposed down-regulation index can be calculated according to the updated control index and the controllable load proportion, and the decomposed down-regulation index is calculated as follows:

[0051] For example, if the updated control index is 1050kW and the controllable load proportion of the transformer area is 20%, the decomposed down-regulation index = 210kW.

[0052] The embodiment obtains the total controllable load of the users participating in the flexible control, decomposes the total control index according to the total controllable load to obtain the decomposed down-regulation index. In the decomposition process of the total control index, a preset redundancy coefficient is introduced to ensure the reliability of the control, and the index is allocated fairly and reasonably according to the controllable load proportion of each transformer area, thereby effectively solving the problems of low control precision and insufficient flexibility in the prior art and improving the precision and efficiency of the power system control.

[0053] Based on the first embodiment of the present application, in the third embodiment of the present application, the same or similar contents as the above-mentioned first embodiment can be referred to the above introduction, and the subsequent will not be described in detail. On this basis, please refer to Figure 4 , step S30 includes steps S301-S303: Step S301: Obtain the device controllable load of each flexible regulation device and the total controllable load of the users participating in the flexible regulation.

[0054] It should be noted that after the terminal generates the decomposed regulation index, the active power adjustment percentage can be uniformly set, and the output power is automatically adjusted to meet the regulation demand of the power grid, so that the device controllable load of each flexible regulation device and the total controllable load of the users participating in the flexible regulation can be obtained.

[0055] The device controllable load of each flexible regulation device refers to the maximum capacity value that can be adjusted in the current state, which has a crucial influence on subsequent index allocation and regulation effect. By obtaining the device controllable load of each device, the terminal of the transformer area can more accurately understand the regulation potential of each device, thereby providing data support for subsequent index allocation. At the same time, the total controllable load of the users participating in the flexible regulation reflects the overall regulation capacity of all users participating in the regulation in the transformer area, and is an important basis for formulating the decomposed regulation index.

[0056] After obtaining the device controllable load of each flexible regulation device and the total controllable load of the users participating in the flexible regulation, the terminal of the transformer area can further integrate and analyze the data to determine the regulation index that each device should bear.

[0057] Step S302: Calculate the active power adjustment percentage according to the device controllable load, the total controllable load, and the decomposed regulation index.

[0058] It should be noted that the active power adjustment percentage can be calculated according to the device controllable load, the total controllable load, and the decomposed regulation index. The active power adjustment percentage is related to the decomposed regulation index, the controllable load proportion of each user, and the active power of the user, so in a feasible implementation manner, step S302 can include steps B11-B13: Step B11: Calculate the single-user controllable load proportion according to the device controllable load and the total controllable load; It should be noted that the single-user controllable load proportion = device controllable load / total controllable load.

[0059] For example, the device controllable load is 200 kW, and the total controllable load is 2000 kW, then the single-user controllable load proportion is 10%.

[0060] Step B12: Obtain the current active power of the single user; In a specific implementation, the current active power of the user can be collected through the State Grid Smart Meter Communication Protocol and the like. This data reflects the actual active power value consumed by the user at the current time, and is one of the key parameters for subsequent calculation of the active power adjustment percentage. By accurately obtaining the current active power, the amount of active power that each user needs to adjust can be more accurately determined to ensure that the regulation effect meets the expectations.

[0061] Step B13: calculating the active power adjustment percentage according to the single-user controllable load proportion, the decomposition down-regulation index, and the current active power.

[0062] In a specific implementation, the active power adjustment percentage can be calculated according to the single-user controllable load proportion, the decomposition down-regulation index, and the current active power, as follows:

[0063] The active power adjustment percentage is the power that all participating users need to adjust, and the percentage of each user does not need to be calculated separately, thereby reducing the calculation complexity and ensuring the fairness of regulation.

[0064] Step S303: regulating the flexible regulation device based on the active power adjustment percentage and the decomposition down-regulation index.

[0065] It should be noted that the flexible regulation device can be accurately regulated according to the active power adjustment percentage and the decomposition down-regulation index. Specifically, the substation terminal issues the calculated active power adjustment percentage to each flexible regulation device, and the device automatically adjusts its active power output according to this percentage and its corresponding decomposition down-regulation index. For example, if the decomposition down-regulation index of a certain flexible regulation device is 100 kW, and the active power adjustment percentage is 10%, and the current active power of the device is 800 kW, the device needs to adjust its active power to 880 kW, i.e. 800 kW + 100 kW x 10% / 10%, which is a simplified explanation. Actual adjustment needs to be made according to specific strategies to meet the regulation needs of the power grid. Through such a regulation method, each flexible regulation device can adjust the power according to the established proportion, achieving the accuracy and efficiency of overall regulation.

[0066] In a feasible implementation, step S303 can include steps C11-C14: Step C11: determining the adjustment range according to the active power adjustment percentage, and generating an initial power adjustment instruction; It should be noted that, for example, the active power adjustment percentage is 10%, indicating that the adjustment range is an increase of 10% or a decrease of 10%, and an initial power adjustment instruction is generated, which is an instruction for adjusting the power of the flexible regulation device.

[0067] Step C12: issuing the initial power adjustment instruction to all the flexible regulation devices in the substation area participating in the flexible regulation, and adjusting the power of the flexible regulation devices by the adjustment amplitude; In a specific implementation, the initial power adjustment instruction can be issued to all the users in the substation area participating in the flexible regulation, wherein the instruction includes the adjustment amplitude of the power, for example, the initial power adjustment instruction is to reduce the current active power by 10%.

[0068] Step C13: collecting the first actual power of the flexible regulation device after the initial adjustment based on the adjustment amplitude; It can be understood that the first actual power of the flexible regulation device after the initial adjustment based on the adjustment amplitude can be collected, and the first actual power reflects the actual power output of the flexible regulation device after receiving the initial power adjustment instruction and performing the initial adjustment. The collection of this data is crucial, as it can directly reflect the effect of the initial adjustment and provide an accurate basis for further adjustment.

[0069] In a feasible implementation, after the first actual power is collected, it can be determined whether the first actual power after aggregation reaches the decomposition reduction target, and therefore, after step C13, the following steps are further included: When the first actual power does not reach the decomposition reduction target, the interval time from the issuance of the instruction to the current time is obtained; When the current interval time is equal to the preset interval time threshold, the step of issuing the initial power adjustment instruction to all the flexible regulation devices in the substation area participating in the flexible regulation and adjusting the power of the flexible regulation devices by the adjustment amplitude is returned, the power of the flexible regulation devices is adjusted by the adjustment amplitude, and the second actual power after the secondary adjustment is collected; When the second actual power reaches the decomposition reduction target, the control is completed.

[0070] It should be noted that if the first actual power does not reach the decomposition reduction target, i.e., the first actual power is less than the decomposition reduction target, the interval time from the issuance of the instruction to the current time can be obtained.

[0071] The preset interval time threshold can be set according to the demand, which is the time interval for each adjustment instruction issuance, for example, it is set to 2 min. When the current interval time is equal to 2 min, the step of issuing the initial power adjustment instruction is performed again, i.e., the step C12 is returned for cyclic iteration, so that the power of the flexible regulation device is adjusted multiple times until the collected actual power is equal to or greater than the decomposition reduction target, and the control is completed.

[0072] Step C14: when the first actual power reaches the decomposition reduction target, the control is completed.

[0073] It should be noted that if the first actual power is equal to or greater than the decomposition down-regulation index, it indicates that the regulation meets the requirements at this time, and the regulation is stopped. Specifically, for example, if the actual down-regulation power of the flexible regulation device is greater than or equal to the decomposition down-regulation index power of the down-regulation, or the actual up-regulation power of the flexible regulation device is greater than or equal to the decomposition down-regulation index power of the up-regulation, the regulation is stopped.

[0074] The fine and progressive regulation of the active power of the group flexible user is realized. When the actual regulation power reaches or exceeds the preset index power, the system automatically stops the regulation, thereby ensuring the efficiency and accuracy of the regulation process.

[0075] In this embodiment, the device controllable load of each flexible regulation device and the total controllable load of the user participating in the flexible regulation are obtained; the active power adjustment percentage is calculated according to the device controllable load, the total controllable load, and the decomposition down-regulation index; and the flexible regulation device is regulated based on the active power adjustment percentage and the decomposition down-regulation index. In this process, the regulation capacity of the device, the load characteristics of the user, and the overall regulation demand of the power grid are fully considered, thereby effectively improving the accuracy and efficiency of the power system regulation.

[0076] For the purpose of facilitating the understanding of the implementation process of the distributed power intelligent regulation method of the transformer area terminal obtained after the above-mentioned embodiment one, please refer to Figure 5 , Figure 5 A brief flowchart of a distributed power intelligent regulation method of a transformer area terminal is provided, specifically: starting, the cloud master station receives the grid regulation index, i.e., the total regulation index, detects whether the transformer area terminal has index execution capability, and if the transformer area terminal does not have index execution capability, the regulation is ended. If the transformer area terminal has index execution capability, the regulation scheme is issued, i.e., the total regulation index is issued to the transformer area terminal, the transformer area terminal performs index decomposition and execution strategy, etc. The isometric adjustment, and monitors whether the peak regulation power meets the decomposed regulation index. If not, it is judged whether it is within the regulation period. If yes, the isometric regulation is continued. If not, the regulation is ended. If the peak regulation power meets the decomposed regulation index, the regulation is ended.

[0077] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the distributed power intelligent regulation method of the transformer area terminal of the present application. More forms of simple transformation based on this technical concept are within the protection scope of the present application.
