[0002] A power distribution system is a modular solution for power distribution and management, and is usually applied to fields such as data centers, industrial facilities, commercial buildings, and residences.

[0003] In the related art, a power distribution system uses a transformer to process the input power distribution into a power distribution with a preset voltage value.

[0004] In view of the above related art, the input power distribution of the power distribution system may have different stabilities. For example, when the power distribution system uses thermal power and wind power at the same time, due to the instability of wind power, it will affect the power distribution of the power distribution system and cause the power distribution effect to decline. Summary of the Invention

[0034] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the following further elaborates on the present application in conjunction with the appended Figure 1 to the appended Figure 9 and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] An embodiment of the present application discloses a distribution system. Referring to Figure 1 , the distribution system includes: a distribution box body 11, distribution equipment 12, and a controller 13.

[0036] The distribution box body is used to place the distribution equipment 12. Optionally, the distribution box body is composed of multiple sub-distribution box bodies, and each sub-distribution box body is used to place at least one piece of distribution equipment 12.

[0037] The distribution equipment 12 includes at least one of a transformer, a UPS (Uninterruptible Power System), a power distribution cabinet, a bypass cabinet, an SVG (Static Var Generator), and a connection cabinet.

[0038] The controller 13 is used to control each piece of distribution equipment 12 in the distribution system to work.

[0039] An embodiment of the present application discloses a control method for a distribution system. Referring to Figure 2 , the method includes: Step S201: Obtain the circuit parameters and stability requirement parameters of the current load equipment in the distribution system.

[0040] The current load equipment refers to the equipment or components connected to the distribution system. For example, the current load equipment includes computers, lights, refrigerators, etc.

[0041] The circuit parameters include at least one of voltage, current, impedance, and rated power. Exemplarily, a voltage sensor is provided in the distribution system, and the voltage sensor can measure the working voltage of a certain load equipment.

[0042] The stability requirement parameter refers to the requirement index of the load device for power supply reliability. Exemplarily, the stability requirement parameter includes the voltage fluctuation range and the allowable power-off duration. Optionally, the stability requirement parameter can be manually input by the technician.

[0043] Step S202: Calculate the total power demand of the current load device according to the circuit parameters.

[0044] The total power demand refers to the total power consumed by all load devices connected to the power distribution system within a unit time. Exemplarily, obtain the rated power of the current load device from the circuit parameters. The total power demand is obtained according to the sum of the rated powers of each load device. Among them, the unit time can be set by the technician himself. For example, the unit time is 1 second, 1 minute or 10 minutes.

[0045] Step S203: Obtain the power supply type used by the power distribution system, and the power supply type includes a stable power supply and an intermittent power supply.

[0046] A stable power supply refers to a power supply that is not affected by environmental factors. An intermittent power supply refers to a power supply that is affected by environmental factors.

[0047] In this embodiment, the stable power supply can refer to power supplies such as the power grid and diesel generators. The intermittent power supply can refer to the power supplies corresponding to wind power generation and photovoltaic power generation.

[0048] Step S204: Calculate the first total power supply amount of the intermittent power supply, and calculate the difference between the total power demand and the first total power supply amount to obtain the second total power supply amount corresponding to the stable power supply.

[0049] The first total power supply amount refers to the total power that the intermittent power supply can provide within a unit time.

[0050] The second total power supply amount refers to the power difference that the stable power supply needs to make up within a unit time.

[0051] For the current load device, its power sources are the stable power supply and the intermittent power supply. Considering energy conservation and environmental protection, it is necessary to first use the power provided by the intermittent power supply and use the power provided by the stable power supply as a supplement.

[0052] Exemplarily, if the intermittent power supply is photovoltaic power generation, set the photovoltaic power generation amount within a unit time as the first total power supply amount.

[0053] Step S205: Calculate the first confidence power supply amount and the first non-confidence power supply amount in the first total power supply amount.

[0054] The first confidence power supply amount refers to the stable part that can be relied on in the intermittent power supply.

[0055] The first non - confidence power supply amount refers to the fluctuating part in the intermittent power source.

[0056] Exemplarily, if the intermittent power source is photovoltaic power generation, the minimum guaranteed output of the photovoltaic power generation is taken as the first confidence power supply amount.

[0057] Step S206: According to the stability requirement parameter, using the first confidence power supply amount, the first non - confidence power supply amount, and the second total power supply amount as the objects to be allocated, perform power distribution for the current load devices.

[0058] Exemplarily, according to the stability requirement parameter, allocate power for the current load devices. Allocate the power sources corresponding to the first confidence power supply amount and the second total power supply amount to the load devices with high stability requirement parameters. Allocate the power source corresponding to the first non - confidence power supply amount to the load devices with low stability requirement parameters.

[0059] By adopting the above - mentioned technical solution, obtain the types of power sources used in the power distribution system. The power source types include stable power sources and intermittent power sources, and based on the stable power sources and intermittent power sources, obtain the first confidence power supply amount, the first non - confidence power supply amount, and the second total power supply amount, so as to further perform power distribution for the current load devices. This solution can achieve reasonable power distribution, ensure that each load device can work normally, and improve the power distribution effect of the power distribution system.

[0060] In the following embodiments, when allocating power for load devices, it is necessary to allocate according to the stability requirement parameters of different load devices, so that the load devices corresponding to high stability requirement parameters can have a stable power supply. Therefore, an embodiment of the present application discloses a method for power distribution of load devices one. Refer to Figure 3 , this method includes: Step S301: Set the load devices in the current load devices whose stability requirement parameters are greater than the stability requirement parameter threshold as the first load devices, and set the load devices in the current load devices whose stability requirement parameters are less than the stability requirement parameter threshold as the second load devices.

[0061] The stability requirement parameter threshold is a preset empirical value, and technicians can adjust the specific value of the stability requirement parameter threshold according to actual needs.

[0062] If the stability requirement parameter of a load device is greater than the stability requirement parameter threshold, it indicates that the load device has a greater demand for stable power supply. If the stability requirement parameter of a load device is less than the stability requirement parameter threshold, it indicates that the load device has a smaller demand for stable power supply.

[0063] Step S302: Calculate the sum of the first confidence power supply amount and the second total power supply amount to obtain the stable power supply amount.

[0064] The first confidence power supply is the part of the electric energy that the intermittent power supply can stably provide. The second total power supply is provided by the stable power supply itself. Therefore, the stable power supply obtained by calculating the sum of the first confidence power supply and the second total power supply refers to the total electric energy that the power distribution system can stably provide.

[0065] The stable power supply refers to the electric energy that the stable power supply and the intermittent power supply can stably provide per unit time.

[0066] Step S303: If the stable power supply is greater than or equal to the power demand corresponding to the first load device, allocate the electric energy corresponding to the stable power supply to the first load device, and allocate the remaining electric energy to the second load device.

[0067] When the stable power supply is greater than or equal to the power demand corresponding to the first load device, it means that the power demand can meet the power supply stability requirement of the first load device. Therefore, directly allocate the electric energy corresponding to the stable power supply to the first load device, and allocate the remaining electric energy to the second load device.

[0068] In this step, the remaining electric energy refers to the difference between the total power demand and the stable power supply.

[0069] Step S304: If the stable power supply is less than the power demand corresponding to the first load device, calculate the difference between the power demand corresponding to the first load device and the stable power supply to obtain the intermittent power supplement value.

[0070] When the stable power supply is less than the power demand corresponding to the first load device, it means that there is a power gap in the stable power supply, and the power demand cannot fully meet the power supply stability requirement of the first load device. Set this part of the power gap as the intermittent power supplement value.

[0071] The intermittent power supplement value comes from the intermittent power supply.

[0072] Step S305: Allocate the electric energy corresponding to the stable power supply and the intermittent power supplement value to the first load device, and allocate the remaining electric energy to the second load device.

[0073] Since the stable power supply cannot meet the demand of the first load device, it is necessary to obtain the intermittent power supplement value from the intermittent power supply as a supplement.

[0074] In this step, the remaining electric energy refers to the electric energy in the total power demand except for the stable power supply and the intermittent power supplement value.

[0075] By adopting the above technical solution, the power supply modes of the first load device and the second load device are set according to the stable power supply amount and the power demand amount corresponding to the first load device. It can ensure the stable power supply of the first load device and improve the power distribution effect of the power distribution system.

[0076] In the following embodiments, in the scenario where the stable power supply amount is less than the power demand amount corresponding to the first load device, the power supply sources of the load devices can be rotated to make the power supply of the first load device as stable as possible. Therefore, Embodiment 2 of a power distribution method for load devices is disclosed in this application. Refer to Figure 4 and the method includes: Step S401: Sort the first load devices in descending order according to the stability requirement parameters to obtain the first load device sequence.

[0077] The first load device in the first load device sequence is sorted from largest to smallest according to the stability requirement parameters.

[0078] Step S402: Classify the first load devices into first stable load devices and first unstable load devices according to the first load device sequence, the stable power supply amount, and the intermittent power supplement value. The first stable load devices correspond to the stable power supply amount, and the first unstable load devices correspond to the intermittent power supplement value.

[0079] Exemplarily, obtain the power demand amounts corresponding to each first load device. According to the sorting of the first load devices in the first load device sequence, obtain the first stable load devices so that the total sum of the power demand amounts of the first stable load devices is not greater than the stable power supply amount. Set the load devices other than the first stable load devices among the first load devices as the first unstable load devices.

[0080] For example, the first load device sequence is load device A, load device B, load device C, and load device D. According to the sorting of the first load devices, preferentially classify the load devices A and B with the top sorting into the first stable load devices.

[0081] Step S403: In response to the expiration of a preset duration, update the first stable load devices and the first unstable load devices according to the first load device sequence.

[0082] The preset duration is a preset empirical value, and those skilled in the art can adjust the specific value of the preset duration according to actual needs.

[0083] Furthermore, the total sum of the power demand amounts corresponding to the updated first stable load devices is not greater than the stable power supply amount.

[0084] Exemplarily, when the first load device sequence is load device A, load device B, load device C, and load device D, load device A and load device B are classified as the first stable load devices, and load device C and load device D are classified as the first unstable load devices. After updating the first stable load devices and the first unstable load devices, load device C and load device D are classified as the first stable load devices, and load device A and load device B are classified as the first unstable load devices.

[0085] By adopting the above technical solution, according to the first load device sequence, the stable power supply amount, and the intermittent power supply supplement value, the first load devices are classified into the first stable load devices and the first unstable load devices. And the first stable load devices and the first unstable load devices are updated every preset time period, so that all the first load devices can obtain stable power supply as much as possible, thereby improving the power distribution effect of the power distribution system.

[0086] In the following embodiments, different processing methods are adopted for different load devices, so as to ensure the reasonable power distribution of the power distribution system. Therefore, an embodiment of the present application discloses an interaction method for load devices. Refer to Figure 5 , the method includes: Step S501: Monitor the input parameters of the power distribution system when the stable power supply amount is less than the preset power threshold.

[0087] The preset power threshold is a preset empirical value, and technicians can adjust the specific value of the preset power threshold according to actual needs.

[0088] The input parameters include power supply side parameters, load side parameters, and environmental parameters. The power supply side parameters include grid voltage, frequency, standby generator output, energy storage SOC (State of Charge), etc. The load side parameters include real-time power, current, power factor, etc. The environmental parameters include wind speed, light intensity, etc.

[0089] Step S502: Obtain the device priority of the current load device at the current moment when it is detected that the input parameters have data fluctuations.

[0090] Data fluctuation means that the change value of the input parameters within the preset time period is greater than the preset change value threshold.

[0091] The device priority is used to represent the importance of different load devices. Optionally, the device priority is pre-input by technicians.

[0092] Step S503: Determine the high-priority load devices and the low-priority load devices from the current load devices according to the device priority and the stable power supply amount.

[0093] In some embodiments, according to the device priority threshold, the current load devices are classified to obtain candidate high-priority load devices and candidate low-priority load devices. The candidate high-priority load devices are adjusted until the total power demand corresponding to the candidate high-priority load devices is less than the stable power supply amount, and the difference between the aforementioned total and the stable power supply amount is less than the preset difference threshold.

[0094] For example, the load devices are divided into high-priority load devices and low-priority load devices. Load devices such as hospital life support systems, data centers, emergency lighting, and communication base stations can be high-priority load devices. Load devices such as electric vehicle chargers, billboards, and non-essential industrial equipment can be low-priority load devices.

[0095] Step S504: Send a preset prompt message to the low-priority load devices and adjust the allocated power of the low-priority load devices.

[0096] In some embodiments, after receiving the preset prompt message, the low-priority load devices will reduce their own operating power according to the preset prompt message. For example, when the low-priority load device is a washing machine, the washing machine will reduce its power or even stop.

[0097] By adopting the above technical solution, high-priority load devices and low-priority load devices are set according to the device priority and the stable power supply amount, a preset prompt message is sent to the low-priority load devices, and the allocated power of the low-priority load devices is adjusted to ensure the power supply of the high-priority load devices.

[0098] An embodiment of the present application discloses an energy distribution optimization method for a power distribution system. Refer to Figure 6 , the method includes: Step S601: Obtain the minimum allowable power of the low-priority load devices.

[0099] The minimum allowable power refers to the minimum operating power for the low-priority load devices to maintain operation. Optionally, the minimum allowable power is pre-input by technicians.

[0100] Step S602: Calculate the minimum allowable power consumption of the low-priority load devices according to the minimum allowable power.

[0101] Exemplarily, the sum of the minimum allowable powers of each low-priority load device is calculated to obtain the minimum allowable power consumption.

[0102] Step S603: Calculate the candidate allocated power corresponding to the low-priority load devices according to the minimum allowable power consumption and the stable power supply amount.

[0103] Exemplarily, the power difference between the stable power supply amount and the minimum allowable power consumption is calculated to obtain the candidate allocated power.

[0104] Step S604: When the candidate allocated power is greater than the minimum allowable power consumption, adjust the allocated power of the load device to the candidate allocated power.

[0105] In some embodiments, a multi-objective optimization method is adopted to optimize the allocated power of the load device to obtain the power allocation method of the load device.

[0106] By adopting the above technical solution, when the candidate allocated power is greater than the minimum allowable power consumption, the allocated power of the load is adjusted to the candidate allocated power. This solution ensures that the candidate allocated power can meet the minimum requirements of the load device, thereby improving the power distribution effect of the power distribution device.

[0107] In the following embodiments, when calculating the first confidence power supply amount and the first non-confidence power supply amount, the calculation can be performed according to the historical operation records of the intermittent power source to ensure the credibility of the first confidence power supply amount and the first non-confidence power supply amount. Therefore, an embodiment of the present application discloses a calculation method for the confidence power supply amount. Refer to Figure 7 , the method includes: Step S701: Obtain the historical operation records of the intermittent power source.

[0108] The historical operation records refer to the power generation data of the intermittent power source in the historical period. Optionally, the power generation data includes the power generation power, output voltage, and internal impedance of the intermittent power source. Among them, the power generation data corresponds to the time stamp one by one.

[0109] For example, the historical operation data includes the power generation power and output voltage of the intermittent power source in the past year.

[0110] Step S702: Extract the average power supply parameters and peak power supply parameters of the intermittent power source from the historical operation records.

[0111] The average power supply parameter refers to the average value of the power generation data. For example, the average power supply parameter is the average voltage of the intermittent power source in the historical period. The peak power supply parameter refers to the peak value of the power generation data. For example, the peak power supply parameter is the peak voltage of the intermittent power source in the historical period.

[0112] In some embodiments, the historical operation records are segmented according to the time stamp to obtain segmented historical operation records. Calculate the segmented average power supply parameters and segmented peak power supply parameters in each segmented historical operation record. Calculate the mean value of the segmented average power supply parameters to obtain the average power supply parameter, and calculate the mean value of the segmented peak power supply parameters to obtain the peak power supply parameter.

[0113] Step S703: Obtain the confidence ratio according to the average power supply parameter and the peak power supply parameter.

[0114] Exemplarily, calculate the ratio of the average power supply parameter to the peak power supply parameter to obtain the confidence ratio.

[0115] Step S704: Calculate the product of the first total power supply amount and the confidence ratio to obtain the first confidence power supply amount.

[0116] The confidence ratio is used to represent the ratio between the effective output and the maximum output of the intermittent power source.

[0117] Step S705: Calculate the difference between the first total power supply amount and the first confidence power supply amount to obtain the first non-confidence power supply amount.

[0118] By adopting the above technical solution, calculating the first non-confidence power supply amount using the historical operation record of the intermittent power source ensures the accuracy of the first non-confidence power supply amount, and further makes the power distribution effect of the power distribution system better.

[0119] In the following embodiments, the intermittent power source will be affected by environmental factors. Therefore, in actual calculation and processing, the confidence ratio can be updated according to the influence of the external environment on the intermittent power source.
