Description

Technical Field

[0001] The present application relates to the field of power distribution technology, and in particular to a control method, system, storage medium and power distribution system for a power distribution system. Background Art

[0002] A power distribution system is a modular solution for distributing and managing electrical power, typically used in data centers, industrial facilities, commercial buildings, and residential buildings.

[0003] In related technologies, power distribution systems use transformers to convert input power into power distribution at a preset voltage. Based on the power requirements of different load devices, power distribution modules are used to adjust the electrical parameters of different power distribution output ports, which correspond to the load devices.

[0004] Regarding the above-mentioned related technologies, the input distribution of the distribution system may have different stabilities. For example, the distribution system uses thermal power and wind power at the same time. At this time, due to the instability of wind power, it will affect the power distribution of the distribution system, resulting in a decrease in the distribution effect. Summary of the Invention

[0068] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1 To the attached Figure 9 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0069] The present application embodiment discloses a power distribution system. Figure 1 The power distribution system includes: a power distribution box 11, a power distribution device 12 and a controller 13.

[0070] The power distribution box is used to place the power distribution equipment 12. Optionally, the power distribution box is composed of multiple sub-distribution boxes, each of which is used to place at least one power distribution equipment 12.

[0071] The power distribution equipment 12 includes at least one of a transformer, an uninterruptible power system (UPS), a feed cabinet, a bypass cabinet, a static var generator (SVG), and a connection cabinet.

[0072] The controller 13 is used to control the operation of each power distribution device 12 in the power distribution system.

[0073] The embodiment of the present application discloses a control method for a power distribution system. Figure 2 , the method comprising:

[0074] Step S201: Obtain circuit parameters and stability requirement parameters of current load devices in the power distribution system.

[0075] Current load devices refer to devices or components connected to the power distribution system. For example, current load devices include computers, lights, refrigerators, etc.

[0076] The circuit parameters include at least one of voltage, current, impedance, and rated power. For example, a voltage sensor is provided in the power distribution system, and the voltage sensor can measure the operating voltage of a load device.

[0077] Stability requirement parameters refer to the load device's power supply reliability requirements. For example, these parameters include voltage fluctuation range and allowable power outage duration. Optionally, these parameters can be manually entered by a technician.

[0078] Step S202: Calculate the total power demand of the current load device according to the circuit parameters.

[0079] Total power demand refers to the total power consumed per unit time by all load devices connected to the power distribution system. For example, the rated power of the current load devices is obtained from the circuit parameters. The total power demand is calculated by summing the rated power of each load device. The unit time can be customized by the technician, for example, 1 second, 1 minute, or 10 minutes.

[0080] Step S203: Acquire the power type used by the power distribution system, where the power type includes stable power supply and intermittent power supply.

[0081] Stable power supply refers to power supply that is not affected by environmental factors. Intermittent power supply refers to power supply that is affected by environmental factors.

[0082] In this embodiment, the stable power source may refer to a power source such as a power grid, a diesel generator, etc. The intermittent power source may refer to a power source corresponding to wind power generation or photovoltaic power generation.

[0083] Step S204: Calculate a first total power supply of the intermittent power supply, and calculate the difference between the total power demand and the first total power supply to obtain a second total power supply corresponding to the stable power supply.

[0084] The first total electric energy supply refers to the total electric energy that the intermittent power supply can provide per unit time.

[0085] The second total power supply refers to the power difference that the stable power supply needs to make up per unit time.

[0086] For current load equipment, its power sources include stable power supply and intermittent power supply. For the sake of energy saving 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.

[0087] Exemplarily, if the intermittent power source is photovoltaic power generation, the photovoltaic power generation per unit time is set as the first total electric energy provided.

[0088] Step S205: Calculate a first trusted electric energy supply amount and a first untrusted electric energy supply amount in the first total electric energy supply amount.

[0089] The first confidence level of power supply refers to the reliable and stable portion of the intermittent power supply.

[0090] The first untrusted electric energy supply refers to the fluctuation portion in the intermittent power supply.

[0091] For example, if the intermittent power source is photovoltaic power generation, the minimum guaranteed output of the photovoltaic power generation is used as the first trusted electric energy supply.

[0092] Step S206: Allocate power to the current load device according to the stability requirement parameter, with the first trusted power supply, the first untrusted power supply, and the second total power supply as objects to be allocated.

[0093] Exemplarily, power is allocated to the current load device according to the stability requirement parameter. The power source corresponding to the first trusted power supply and the second total power supply is allocated to the load device with a high stability requirement parameter. The power source corresponding to the first untrusted power supply is allocated to the load device with a low stability requirement parameter.

[0094] By adopting the above technical solution, the power supply type used by the power distribution system is obtained, including stable power supply and intermittent power supply. Based on the stable power supply and intermittent power supply, a first trusted power supply, a first untrusted power supply, and a second total power supply are obtained, thereby further allocating power to the current load device. This solution can achieve reasonable power distribution, ensure the normal operation of each load device, and improve the power distribution efficiency of the power distribution system.

[0095] In the following embodiments, when distributing electric energy to load devices, it is necessary to distribute it according to the stability requirement parameters of different load devices, so that the load devices corresponding to the high stability requirement parameters can have a stable power supply. Therefore, the embodiment of the present application discloses a method for distributing electric energy to load devices. Figure 3 , the method comprising:

[0096] Step S301: setting the load device whose stability requirement parameter is greater than the stability requirement parameter threshold in the current load device as the first load device, and setting the load device whose stability requirement parameter is less than the stability requirement parameter threshold in the current load device as the second load device.

[0097] The stability requirement parameter threshold is a preset empirical value, and technical personnel can adjust the specific value of the stability requirement parameter threshold according to actual needs.

[0098] If the stability requirement parameter of the load device is greater than the stability requirement parameter threshold, it means that the load device has a greater demand for stable power supply. If the stability requirement parameter of the load device is less than the stability requirement parameter threshold, it means that the load device has a smaller demand for stable power supply.

[0099] Step S302: Calculate the sum of the first confidence power supply amount and the second total power supply amount to obtain a stable power supply amount.

[0100] The first confidence level of electric energy provided is part of the electric energy that can be stably provided by the intermittent power supply, and the second total electric energy provided is itself provided by the stable power supply. Therefore, the stable electric energy provided by calculating the sum of the first confidence level of electric energy provided and the second total electric energy provided refers to the total electric energy that can be stably provided by the power distribution system.

[0101] Stable power supply refers to the power that can be stably provided by stable power supply and intermittent power supply per unit time.

[0102] Step S303: If the stable power supply is greater than or equal to the power demand corresponding to the first load device, allocate power corresponding to the stable power supply to the first load device, and allocate the remaining power to the second load device.

[0103] 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, the power corresponding to the stable power supply is directly allocated to the first load device, and the remaining power is allocated to the second load device.

[0104] In this step, the surplus electric energy refers to the difference between the total electric energy demand and the stable electric energy supply.

[0105] Step S304: If the stable power supply is less than the power demand corresponding to the first load device, the difference between the power demand corresponding to the first load device and the stable power supply is calculated to obtain an intermittent power supplement value.

[0106] 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. This part of the power gap is set as the intermittent power supplement value.

[0107] Intermittent power supplement value comes from intermittent power sources.

[0108] Step S305: Allocate the electric energy corresponding to the stable electric energy supply amount and the intermittent electric energy supplement value to the first load device, and allocate the remaining electric energy to the second load device.

[0109] Since the stable power supply cannot meet the demand of the first load device, it is necessary to obtain intermittent power supplement value from the intermittent power source as a supplement.

[0110] In this step, the remaining electric energy refers to the electric energy in the total electric energy demand excluding the stable electric energy supply and the intermittent electric energy supplement value.

[0111] By adopting the above technical solution, the energy supply mode of the first load device and the second load device is set according to the stable power supply amount and the power demand corresponding to the first load device. This can ensure the stable power supply of the first load device and improve the power distribution effect of the power distribution system.

[0112] In the following embodiment, in a scenario where the amount of stable power provided is less than the power demand corresponding to the first load device, the power supply of the load device can be rotated to make the power supply of the first load device as stable as possible. Therefore, the embodiment of the present application discloses a second method for distributing power to the load device. Figure 4 , the method comprising:

[0113] Step S401: sorting the first load devices in descending order according to the stability requirement parameter to obtain a first load device sequence.

[0114] The first load devices in the first load device sequence are sorted from largest to smallest according to the stability requirement parameter.

[0115] Step S402: Classify the first load device into a first stable load device and a first unstable load device according to the first load device sequence, the stable power supply amount, and the intermittent power supplement value, wherein the first stable load device corresponds to the stable power supply amount, and the first unstable load device corresponds to the intermittent power supplement value.

[0116] Exemplarily, the power demand corresponding to each first load device is obtained. A first stable load device is obtained by sorting the first load devices within the first load device sequence, such that the sum of the power demand of the first stable load devices is no greater than the stable power supply. The load devices in the first load device sequence, excluding the first stable load devices, are set as first unstable load devices.

[0117] For example, the first load device sequence is load device A, load device B, load device C, and load device D. According to the order of the first load devices, load device A and load device B, which are ranked first, are preferentially classified as first stable load devices.

[0118] Step S403: In response to the preset time period expiring, the first stable load device and the first unstable load device are updated according to the first load device sequence.

[0119] The preset duration is a preset empirical value, and technicians can adjust the specific value of the preset duration according to actual needs.

[0120] Furthermore, the updated total power demand corresponding to the first stable load device is not greater than the stable power supply.

[0121] For example, when the first load device sequence is load device A, load device B, load device C, and load device D, load devices A and load devices B are classified as first stable load devices, and load devices C and load devices D are classified as first unstable load devices. After the first stable load device and the first unstable load device are updated, load devices C and load devices D are classified as first stable load devices, and load devices A and load devices B are classified as first unstable load devices.

[0122] By adopting the above technical solution, the first load devices are classified into first stable load devices and first unstable load devices based on the first load device sequence, stable power supply, and intermittent power replenishment value. Furthermore, the first stable load devices and first unstable load devices are updated every preset period of time, ensuring that all first load devices receive the most stable power supply possible, thereby improving the power distribution efficiency of the power distribution system.

[0123] In the following embodiments, different processing methods are used for different load devices to ensure the reasonable distribution of the power distribution system. Therefore, the embodiment of the present application discloses an interactive method for load devices. Figure 5 , the method comprising:

[0124] Step S501: When the amount of stable electric energy provided is less than a preset electric energy threshold, monitor input parameters of the power distribution system.

[0125] 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.

[0126] Input parameters include power supply parameters, load parameters, and environmental parameters. Power supply parameters include grid voltage, frequency, backup generator output, and energy storage SOC (State of Charge). Load parameters include real-time power, current, and power factor. Environmental parameters include wind speed and sunlight intensity.

[0127] Step S502: when it is detected that the input parameter generates data fluctuations, the device priority of the current load device at the current moment is obtained.

[0128] Data fluctuation refers to the change in the input parameter within a preset time period being greater than the preset change value threshold.

[0129] Device priority is used to indicate the importance of different load devices. Optionally, device priority is pre-entered by the technician.

[0130] Step S503: According to the device priority and the stable power supply, a high-priority load device and a low-priority load device are determined from the current load devices.

[0131] In some embodiments, the current load devices are classified according to a device priority threshold to obtain candidate high-priority load devices and candidate low-priority load devices. The candidate high-priority load devices are adjusted until the sum of the power demands corresponding to the candidate high-priority load devices is less than the stable power supply, and the difference between the sum and the stable power supply is less than a preset difference threshold.

[0132] For example, loads can be categorized as high-priority and low-priority. High-priority loads include hospital life support systems, data centers, emergency lighting, and communication base stations. Low-priority loads include electric vehicle charging stations, billboards, and non-essential industrial equipment.

[0133] Step S504: Sending preset prompt information to the low-priority load device and adjusting the distributed power of the low-priority load device.

[0134] In some embodiments, after receiving the preset prompt information, the low-priority load device will reduce its own operating power according to the preset prompt information. For example, when the low-priority load device is a washing machine, the washing machine will reduce its own power or even stop.

[0135] By adopting the above technical solution, high-priority load devices and low-priority load devices are set according to the device priority and stable power supply, preset prompt information is sent to the low-priority load devices, and the distributed power of the low-priority load devices is adjusted to ensure the power supply of the high-priority load devices.

[0136] The embodiment of the present application discloses a method for optimizing the distribution of electric energy in a power distribution system. Figure 6 , the method comprising:

[0137] Step S601: Obtain the minimum allowable power of the low priority load device.

[0138] The minimum allowable power is the minimum operating power at which the low priority load device can maintain operation. Optionally, the minimum allowable power is pre-entered by the technician.

[0139] Step S602: Calculate the minimum allowable power consumption of the low-priority load device according to the minimum allowable power.

[0140] Exemplarily, the sum of the minimum allowable powers of the various low-priority load devices is calculated to obtain the minimum allowable power consumption.

[0141] Step S603: Calculate candidate power allocations corresponding to low-priority load devices based on the minimum allowable power consumption and the stable power supply.

[0142] Exemplarily, the power difference between the stable power supply and the minimum allowable power consumption is calculated to obtain the candidate power distribution.

[0143] Step S604: When the candidate allocated power is greater than the minimum allowable power consumption, the allocated power of the load device is adjusted to the candidate allocated power.

[0144] In some embodiments, a multi-objective optimization method is used to optimize the distribution of electric energy to the load device to obtain an electric energy distribution method for the load device.

[0145] By adopting the above technical solution, when the candidate allocated power is greater than the minimum allowable power consumption, the load's allocated power is adjusted to the candidate allocated power. This solution ensures that the candidate allocated power can meet the minimum demand of the load equipment, thereby improving the power distribution effect of the distribution equipment.

[0146] In the following embodiment, when calculating the first trusted power supply amount and the first untrusted power supply amount, the calculation can be performed based on the historical operation record of the intermittent power supply to ensure the credibility of the first trusted power supply amount and the first untrusted power supply amount. Therefore, the embodiment of the present application discloses a method for calculating the trusted power supply amount. Figure 7 , the method comprising:

[0147] Step S701: Obtain historical operation records of the intermittent power supply.

[0148] Historical operation records refer to the power generation data of an intermittent power source over a historical period. Optionally, this power generation data includes the power generation, output voltage, and internal impedance of the intermittent power source. The power generation data corresponds to a timestamp.

[0149] For example, historical operating data includes the generated power and output voltage of an intermittent power source over the past year.

[0150] Step S702: extracting average power supply parameters and peak power supply parameters of the intermittent power supply from historical operation records.

[0151] Average power supply parameters refer to the average value of power generation data. For example, the average power supply parameter is the average voltage of an intermittent power source over a historical period. Peak power supply parameters refer to the peak value of power generation data. For example, the peak power supply parameter is the peak voltage of an intermittent power source over a historical period.

[0152] In some embodiments, the historical operation records are segmented according to timestamps to obtain segmented historical operation records. A segmented average power supply parameter and a segmented peak power supply parameter are calculated for each segmented historical operation record. The mean of the segmented average power supply parameters is calculated to obtain the average power supply parameter, and the mean of the segmented peak power supply parameters is calculated to obtain the peak power supply parameter.

[0153] Step S703: Obtain a confidence ratio according to the average power supply parameter and the peak power supply parameter.

[0154] Exemplarily, the ratio of the average power supply parameter to the peak power supply parameter is calculated to obtain the confidence ratio.

[0155] Step S704: Calculate the product of the first total power supply amount and the confidence ratio to obtain a first confidence power supply amount.

[0156] The confidence ratio is used to express the ratio between the effective output and the maximum output of an intermittent power supply.

[0157] Step S705: Calculate the difference between the first total electric energy supply amount and the first trusted electric energy supply amount to obtain a first untrusted electric energy supply amount.

[0158] By adopting the above technical solution, the first untrusted power supply is calculated using the historical operation record of the intermittent power supply, which ensures the accuracy of the first untrusted power supply and thus improves the power distribution effect of the power distribution system.

[0159] In the following embodiments, intermittent power supply may be affected by environmental factors, so in actual calculation and processing, the confidence ratio may be updated according to the impact of the external environment on the intermittent power supply. Therefore, the embodiment of the present application discloses a method for updating the confidence ratio. Figure 8 , the method comprising:

[0160] Step S801: Acquire environmental parameters according to the type of the intermittent power supply, which affect the output parameters of the intermittent power supply.

[0162] Exemplarily, when the intermittent power source is photovoltaic power generation, the environmental parameters include light intensity and temperature.

[0163] Step S802: predicting the future output parameters of the intermittent power supply in a future period according to the environmental parameters.

[0164] For example, the corresponding future output parameters are detected in a preset mapping database according to the environmental parameters. The data in the mapping database is obtained by technicians measuring the output parameters of the intermittent power supply under different environmental parameters.

[0165] Step S803: Update the confidence ratio according to future output parameters.

[0166] Exemplarily, the average of the future output parameter and the peak power supply parameter is calculated to obtain the updated peak power supply parameter, and the ratio of the average power supply parameter to the updated peak power supply parameter is calculated to update the confidence ratio.
