[0035] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0036] With the growth of household electricity demand and the increasing attention to energy conservation and environmental protection, household energy storage systems have been widely used. However, in existing energy storage systems, the output power of each power supply device is usually relatively consistent after connecting to the power load, and each power supply device outputs the same power to meet the power supply demand of the power load. However, in the face of changing power demand, it is often impossible to effectively adjust the output power of multiple power supply devices, resulting in low system efficiency or insufficient power supply.

[0037] In order to solve the above problems, this embodiment provides a household energy storage power distribution method, which can intelligently adjust the output ratio of each power supply device according to the power supply demand to improve the power supply efficiency.

[0038] Among them, there are multiple DC devices connected in the home energy storage system, and the DC device refers to a device that processes direct current. In this embodiment, the DC device is a power supply device, which is a power supply end device that uses direct current, including a DC power supply that can provide stable DC voltage and current for other devices, a solar photovoltaic system that generates direct current under sunlight conditions, a battery energy storage system that stores electrical energy and provides direct current when needed, and a DC generator that generates direct current for use by other devices.

[0039] Different electrical devices can be connected to the home energy storage system. The electrical devices need to consume DC power to operate, including DC-driven household appliances, DC charging equipment, and DC motors that use DC power to drive machinery.

[0040] like Figure 1 As shown, the household energy storage power allocation method implemented in this embodiment specifically includes the following steps:

[0041] Step S1: Obtain the maximum output power of each power supply device under the current actual efficiency, and calculate the total power supply capacity according to the maximum output power of each power supply device.

[0042] Specifically, step S11: obtaining theoretical performance data and current performance data of each power supply device.

[0043] Theoretical performance data refers to the theoretical parameters provided by the manufacturer of the power supply equipment when the equipment leaves the factory, including efficiency curves or tables at different power outputs, temperature data of the power supply equipment under standard conditions, and the theoretical maximum output power of the power supply equipment under standard conditions.

[0044] Among them, the horizontal axis X-axis of the efficiency curve represents the output power of the power supply equipment (usually in watts W), from the minimum output power to the maximum output power; the vertical axis Y-axis represents the efficiency (η) of the power supply equipment at different output powers, usually as a percentage (%), that is, the ratio of input power converted into effective output power.

[0045] The current performance data includes the internal and external temperatures of the equipment during its current operation, the current output power, the power and voltage values ​​during the equipment's operation, the response time of the equipment's response instructions, etc. The health status of the power supply equipment can be determined through the current performance data. The current performance data can be obtained through the communication channel between the system and each power supply equipment. The system sends a query instruction to each power supply equipment through the communication channel. After receiving the query instruction, the controller of the power supply equipment can return its current performance data.

[0046] Step S12: determining the actual efficiency of each power supply device in the current device state according to the current performance data and the efficiency curve.

[0047] Since factors such as health status and temperature will directly affect equipment efficiency, for example, the health status of the equipment (such as aging, wear, etc.) will lead to a decrease in efficiency. In the efficiency curve, the degradation of the health status is usually manifested as an overall downward shift of the efficiency curve. In the efficiency curve, the impact caused by temperature changes is usually manifested as a distortion of the efficiency curve in certain power ranges. For example, under high temperature conditions, the efficiency of the equipment may be significantly reduced in the medium and high power ranges, and the curve may shift downward in these areas.

[0048] Therefore, the device status is determined based on the current performance data, thereby determining the actual efficiency of the power supply device under the current device status. Specifically:

[0049] This embodiment determines the current output power of the device by collecting the current performance data of the power supply device, and finds a point corresponding to the current output power of the device on the device efficiency curve. This point shows the theoretical efficiency of the power supply device at this specific power.

[0050] Based on the performance data of the power supply equipment, factors that may affect the efficiency, such as equipment health status, temperature, and maintenance history, are determined, and corresponding adjustment factors are applied based on the above factors to correct the theoretical efficiency.

[0051] Furthermore, the adjustment factor is determined as follows:

[0052] Step S121: Collect performance data corresponding to the power supply equipment under standard test conditions, which data can be provided by the manufacturer.

[0053] Step S122: Calculate the performance difference between the current performance data of the power supply equipment and the performance data under standard test conditions; taking the temperature data of the photovoltaic panel as an example, the current ambient temperature of the photovoltaic panel is 35°C, and the ambient temperature of the photovoltaic panel under standard test conditions is 25°C, then the temperature difference is 10°C.

[0054] Step S123: Determine the attenuation rate according to the law that the efficiency changes with the performance parameters. The attenuation rate can be obtained based on the data provided by the manufacturer or through experimental measurement. Taking photovoltaic panels as an example, according to the efficiency curve, the efficiency of photovoltaic panels decreases with the increase of temperature. For every increase of 1°C, the efficiency decreases by about 0.5%. Therefore, the attenuation rate is 0.5%.

[0055] Step S124: Calculate the efficiency adjustment factor using the following formula:

[0056] Adjustment factor = 1-attenuation rate*performance difference.

[0057] Taking photovoltaic panels as an example, the adjustment factor = 1-0.5%×ΔT, where ΔT is the temperature difference.

[0058] When multiple factors affect equipment efficiency at the same time, a separate adjustment factor can be calculated for each influencing factor, and all separate adjustment factors can be combined to obtain the total adjustment factor.

[0059] Method of comprehensive adjustment factor:

[0060] Multiplication method: Multiply all individual adjustment factors: Total adjustment factor = adjustment factor 1 × adjustment factor 2 × … × adjustment factor n;

[0061] Additive method: Add the effects of all individual adjustment factors (applicable to situations with smaller impacts): Total adjustment factor = 1-(impact 1 + impact 2 + ... + impact n);

[0062] The most adverse impact method: select the single adjustment factor that has the greatest impact on efficiency.

[0063] Step S125: Correct the theoretical efficiency according to the adjustment factor to obtain the actual efficiency of the power supply equipment.

[0064] The actual efficiency of the power supply equipment is expressed by the following formula:

[0065] Actual efficiency = theoretical efficiency × adjustment factor.

[0066] Step S13: optimizing the theoretical maximum output power of each power supply device according to the actual efficiency of each power supply device to obtain the optimized maximum output power, and calculating the total power supply capacity according to the maximum output power of each power supply device.

[0067] The optimization formula is:

[0068] P 最大输出功率 = Actual efficiency * P 理论最大输出功率 .

[0069] The maximum output powers of all power supply devices after optimization are summed up to obtain the total power supply capacity.

[0070] Step S2: Obtain instantaneous power demand. When the instantaneous power demand is lower than or equal to the total power supply capacity, generate allocation instructions according to the available power ratio of each power supply device, and allocate the instantaneous power demand according to the allocation instructions to determine the actual output power of each power supply device.

[0071] The instantaneous power demand can be obtained by filtering the power demand data, where the power demand data includes the power of the designated power-consuming equipment; the noise signal in the power demand data is determined according to the power demand data, and the noise signal is filtered to obtain the instantaneous power demand.

[0072] Furthermore, the noise signal can be determined through statistical analysis, filtering technology, data visualization, etc. Statistical analysis is to calculate the statistical indicators of the data, such as mean, variance, and standard deviation. Abnormally high variance may indicate the presence of noise. Filtering technology is to use low-pass filters to remove high-frequency noise and retain low-frequency power demand signals; use bandpass filters to remove signal parts that are not within a specific frequency range. Data visualization technology is to draw a time series graph to observe data fluctuations. Abnormal spikes or irregular fluctuations can be identified as noise. Filter the noise signal to obtain a more accurate instantaneous demand value.

[0073] At the same time, based on historical electricity consumption data and current instantaneous power supply demand, the time series analysis model can be used to predict the future short-term power supply demand change trend, which can be used to guide the system to adjust the output of power supply equipment in advance to prevent insufficient or excessive power supply.

[0074] The filtered instantaneous power demand is compared with the total power supply capacity calculated in step S1. When the instantaneous power demand is lower than or equal to the total power supply capacity, an allocation instruction is generated according to the available power ratio of each power supply device, and the instantaneous power demand is allocated according to the allocation instruction to determine the actual output power of each power supply device.

[0075] Specifically, allocating instantaneous power supply demand according to the allocation instruction to determine the actual output power of each power supply device includes:

[0076] Calculate the ratio between the maximum output power of the power supply equipment and the total power supply capacity to determine the available power ratio of the power supply equipment;

[0077] The available power ratio of the power supply equipment is multiplied by the instantaneous power supply demand to determine the actual output power of the power supply equipment; that is, according to the available power ratio of each power supply equipment, the instantaneous power demand required by the current household is allocated to the actual output power of each power supply equipment, so that each power supply equipment undertakes the corresponding power supply task according to its available power ratio, thereby optimizing the operating efficiency and resource utilization of the entire power system.

[0078] Another situation is that step S3 is executed when the instantaneous power demand exceeds the total power supply capacity.

[0079] Step S3: When the instantaneous power demand exceeds the total power supply capacity, a full-power operation instruction is generated to control each power supply device to switch to the full-power operation state, that is, to control each power supply device to output its corresponding maximum output power to try to meet the current household electricity demand.

[0080] In some embodiments, Figure 2 As shown, the system continuously monitors the power demand and the operating status of each device, and promptly detects and responds to changes in demand. Specifically:

[0081] Obtain the operating data of each power supply device, including device temperature data and operating log;

[0082] Determine whether the power supply equipment has any abnormality based on the operating data. If any power supply equipment has an abnormality, generate an abnormal adjustment instruction. The abnormal adjustment instruction is used to adjust the output power of the power supply equipment with the abnormality to zero, and recalculate the available power ratio of the remaining power supply equipment to adjust the actual output power of each power supply equipment to ensure the overall power supply stability of the system.

[0083] In some embodiments, users interact with the system through an application on a smartphone or tablet device, and can view the system's power supply status, the operation of each power supply device, and the overall efficiency of the system in real time. When the system enters full power output mode or an equipment abnormality occurs, the system sends a notification to the user through the application to remind the user to take appropriate measures, such as reducing unnecessary power consumption or contacting maintenance services.

[0084] At the same time, users can manually adjust the output power limit of certain power supply devices through the application. After receiving the correction instruction for adjusting the output power limit, the system automatically adjusts the output power limit of the specified power supply device according to the modification instruction; and recalculates the total power supply capacity according to the output power limit of the specified power supply device and the maximum output power of other power supply devices to adjust the actual output power of each power supply device, which is equivalent to automatically recalculating and applying the new power allocation strategy to ensure that the system can meet user needs while maintaining efficient operation.

[0085] This embodiment can adjust the actual output power of each power supply device according to the available power ratio of each power supply device when the instantaneous power demand is lower than or equal to the total power supply capacity, and control each power supply device to switch to the full-power operation state when the instantaneous power demand exceeds the total power supply capacity, thereby achieving the effect of dynamically adjusting the output power of multiple power supply devices; and this embodiment also considers the output efficiency of each power supply device in the current environment and the current health state to determine the maximum output power of each power supply device, thereby calculating the total power supply capacity of the home energy storage system, which can accurately evaluate the power supply capacity of each power supply device and improve the accuracy of the subsequent dynamic adjustment of the output power of each power supply device.
