[0002] Virtualization technology is being gradually applied to power supply systems such as photovoltaic-storage and integrated photovoltaic-storage-charging systems. This technology divides a physical system into multiple independent virtual subsystems, each of which can operate independently according to different operating strategies (such as maximum self-consumption, time-of-use pricing, or virtual power plant dispatch). This effectively avoids the risks of overcharging and over-discharging, suppresses the volatility of photovoltaic power generation, and improves the overall energy utilization efficiency of the system.

Detailed Implementation

[0026] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0027] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] The following description, in conjunction with the accompanying drawings, details the power parameter determination method, power parameter determination device, electronic device, and readable storage medium provided in the embodiments of this application through specific implementations and application scenarios.

[0029] The power parameter determination method provided in this application embodiment can be executed by an electronic device or a functional module or functional entity in an electronic device that can implement the power parameter determination method. The following uses an electronic device as the execution subject to illustrate the power parameter determination method provided in this application embodiment.

[0030] The power parameter determination method provided in this application is used in a power supply system, which includes multiple power supply components, and the power supply components are divided into multiple virtualized subsystems.

[0031] In this embodiment, the power supply components of the photovoltaic-storage and photovoltaic-storage-charging power supply systems are divided into virtualized subsystems using virtualization avatar technology. Each subsystem can operate independently according to different operating strategies, effectively avoiding the risks of overcharging and over-discharging, suppressing the volatility of photovoltaic power generation, and improving the overall energy utilization efficiency of the system.

[0032] For example, such as Figure 2 As shown, the original photovoltaic-storage system includes power supply components such as strings, photovoltaic-storage inverters, and batteries. Through virtualization sharding technology, the original photovoltaic-storage system is divided into multiple virtual photovoltaic-storage systems, including photovoltaic-storage system 1 and photovoltaic-storage system 2. The operating modes of the two systems can be set independently (such as maximum self-consumption, virtual power plant dispatch, etc.). The strings are virtualized into string 1 and string 2, the photovoltaic-storage inverters are virtualized into photovoltaic-storage inverter 1 and photovoltaic-storage inverter 2, and the batteries are virtualized into battery 1 and battery 2.

[0033] It should be noted that, at the physical level, the power supply system (or power supply component) is still a complete device, and the power information that the data acquisition device can collect is the power of the power supply system (or power supply component).

[0034] For example, such as Figure 3 As shown, the power supply component is a photovoltaic-storage inverter, which is virtualized into n virtualized subsystems, namely photovoltaic-storage inverter 1, photovoltaic-storage inverter 2, ..., photovoltaic-storage inverter n.

[0035] In this embodiment, the power information that the data acquisition device can collect is the actual operating power of the photovoltaic-storage inverter. For photovoltaic-energy storage inverter 1, photovoltaic-energy storage inverter 2, ... photovoltaic-energy storage inverter n, which are obtained by virtual partitioning, the actual operating power of each virtual photovoltaic-energy storage inverter cannot be obtained by sampling. , … .

[0036] This application provides a method for determining power parameters, which can accurately calculate the actual power and loss of each virtualized subsystem, providing data support for energy flow visualization, status monitoring, and system optimization scheduling.

[0037] like Figure 1 As shown, the method for determining the power parameters includes steps 110 and 120.

[0038] Step 110: Obtain the actual power information and reference power information of the power supply components.

[0039] It is understandable that actual power information refers to the actual power information of the power supply component during real-time operation. The actual power information of the power supply component includes the actual operating power and power loss of the power supply component.

[0040] It is understandable that operating power can be the actual output power of the power supply component during operation; power loss refers to the power lost by the power supply component during operation due to factors such as heat generation and friction, and this part of the power cannot be used for output.

[0041] In this embodiment, the actual power information of the power supply component can be obtained by sampling through a data acquisition device.

[0042] Reference power information refers to the expected power that the power supply system requires power supply components to achieve under the current control strategy or operating mode, i.e., the power target value. The reference power information of power supply components includes the reference operating power that the power supply components should achieve.

[0043] In this embodiment, the reference power information can be dynamically set by external commands (such as grid dispatch, energy management, etc.) or internal control algorithms (such as maximum power point tracking MPPT) to guide the real-time power adjustment of power supply components.

[0044] It should be noted that due to factors such as changes in environmental and input conditions, equipment performance limitations, and power grid or load disturbances, the actual operating power of the power supply components may differ from the reference operating power and are not completely equal.

[0045] Step 120: Based on the actual power information and reference power information, determine the actual power parameters of the virtualization subsystem according to the proportional division method or the priority division method.

[0046] The actual power parameters of the virtualization subsystem include at least one of the actual operating power and the actual power loss.

[0047] In this embodiment, the power supply component is divided into multiple virtualization subsystems. Based on the actual power information and reference power information of the power supply component, the actual operating power and actual power loss of each virtualization subsystem can be determined according to the proportional division method or the priority division method.

[0048] Taking a photovoltaic-storage inverter as an example, which is the power supply component.

[0049] like Figure 3 As shown, the photovoltaic-storage inverter is virtualized into n virtualized subsystems, namely photovoltaic-storage inverter 1, photovoltaic-storage inverter 2, ..., photovoltaic-storage inverter n. The reference operating power of the virtualized subsystem is... The actual operating power of the virtualization subsystem is , This is the sequence number of the virtualization subsystem. =1, 2, ..., n.

[0050] The sum of the actual operating power of photovoltaic-storage inverter 1, photovoltaic-storage inverter 2, ... photovoltaic-storage inverter n is equal to the actual operating power of the power supply component photovoltaic-storage inverter, calculated as follows:

[0051] in, The actual operating power of the photovoltaic-storage inverter can be obtained through voltage and current sampling.

[0052] The sum of the reference operating power of photovoltaic-energy storage inverter 1, photovoltaic-energy storage inverter 2, ... photovoltaic-energy storage inverter n is equal to the reference operating power of the power supply component photovoltaic-energy storage inverter, and the calculation formula is as follows:

[0053] in, The reference operating power for the photovoltaic-storage inverter is set by external commands or internal control algorithms.

[0054] In practice, due to factors such as inverter derating, the actual operating power of the power supply components is not exactly equal to the reference operating power. , that is:

[0055] It is understandable that the actual operating power of each virtualization subsystem may not be able to track the instructions, meaning there is a difference between the actual operating power of the virtualization subsystem and the reference operating power.

[0056] It should be noted that, through virtualization sharding technology, the power supply component is divided into multiple virtualization subsystems. Each virtualization subsystem operates independently according to different operating strategies. The reference operating power of the virtualization subsystem can be obtained according to the scheduling instructions of the upper-level system or the preset operating strategy. The obtained reference power information of the power supply component includes the total reference operating power of the power supply component and the reference operating power of each virtualization subsystem.

[0057] In this embodiment, the actual operating power of the power supply component is allocated to each virtualization subsystem according to a proportional allocation method or a priority allocation method, so that the sum of the actual operating power of each virtualization subsystem is equal to the actual operating power of the power supply component. Similarly, the actual operating power of the power supply component can also be allocated to each virtualization subsystem, so that the sum of the actual power loss of each virtualization subsystem is equal to the actual power loss of the power supply component.

[0058] It should be noted that the power difference between the actual power and the reference power of the power supply component is essentially due to the dynamic uncertainty in the energy conversion process. Based on this characteristic, by using the actual power information and reference power information of the power supply component as the allocation basis, and combining the power balance constraint (the sum of the actual operating power of each virtualization subsystem equals the actual operating power of the power supply component) and the loss balance constraint (the sum of the actual loss power of each virtualization subsystem equals the actual loss power of the power supply component), the actual operating power and actual loss power of each virtualization subsystem can be accurately calculated, effectively addressing the impact of dynamic uncertainty.

[0059] In this embodiment, the proportional allocation method and the priority allocation method are two implementation methods for allocating power to power supply components. Both are used to determine the actual power parameters of the virtualization subsystem. The allocation is based on the actual power information and reference power information of the power supply components, and the allocation target is that the sum of the actual operating power of each virtualization subsystem is equal to the actual operating power of the power supply components, and / or the sum of the actual loss power of each virtualization subsystem is equal to the actual loss power of the power supply components. This allows for accurate calculation of the actual operating power and / or actual loss power of each virtualization subsystem, providing data support for energy flow visualization, status monitoring, and system optimization scheduling.

[0060] Among them, the proportional allocation method refers to dividing the overall power into a portion of the power of multiple virtualization subsystems according to a ratio, and then allocating it to each virtualization subsystem. The priority allocation method refers to setting a corresponding priority for each virtualization subsystem and allocating the overall power to the virtualization subsystem with the target priority.

[0061] According to the power parameter determination method provided in the embodiments of this application, by obtaining the actual power information and reference power information of the power supply components, and using the actual power information and reference power information of the power supply components as the allocation basis, the actual operating power and / or actual power loss of each virtualization subsystem are determined according to the proportional division method or the priority division method. The actual power and loss of each virtualization subsystem can be accurately calculated, providing data support for energy flow visualization, status monitoring and system optimization scheduling.

[0062] It is understandable that the reference power information of the power supply component is obtained, which includes the reference total operating power of the power supply component and the reference operating power of the virtualization subsystem. The sum of the reference operating power of each virtualization subsystem is equal to the reference total operating power of the power supply component. The actual power information of the power supply component is obtained, which may include the actual total operating power and the actual total power loss of the power supply component. The sum of the actual operating power of each virtualization subsystem is equal to the actual total operating power of the power supply component, and the sum of the actual power loss of each virtualization subsystem is equal to the actual total power loss of the power supply component.

[0063] The embodiments of this application will be described in detail below from two different implementation perspectives: proportional division and priority division.

[0064] I. Proportional division method.

[0065] In some embodiments, determining the actual operating power of the virtualization subsystem according to a proportional division method includes: The first power allocation ratio is determined based on the reference total operating power and the actual total operating power; The actual operating power of the virtualization subsystem is determined based on the first power allocation ratio and the reference operating power of the virtualization subsystem.

[0066] In this embodiment, the ratio of the actual total operating power of the power supply component to the reference total operating power can be used as the first power allocation ratio. The actual total operating power is allocated to each virtualization subsystem according to the first power allocation ratio. The product of the first power allocation ratio and the reference operating power of the virtualization subsystem is calculated to obtain the actual operating power of the virtualization subsystem.

[0067] For example, the photovoltaic-storage inverter can be virtualized into n virtualized subsystems, namely photovoltaic-storage inverter 1, photovoltaic-storage inverter 2, ..., photovoltaic-storage inverter n, and the reference operating power of the virtualized subsystem is: The actual operating power of the virtualization subsystem is , This is the sequence number of the virtualization subsystem. =1, 2, ..., n.

[0068] The actual total operating power of the photovoltaic-storage inverter is The reference total operating power of the photovoltaic-storage inverter is The formula for calculating the first power allocation ratio is as follows:

[0069] in, This is the first power allocation ratio.

[0070] For photovoltaic-energy storage inverters The first power allocation ratio and the photovoltaic-storage inverter Multiply by the reference operating power to obtain the photovoltaic-storage inverter. The actual operating power is calculated using the following formula:

[0071] in, For photovoltaic-storage inverters Actual operating power For the first power allocation ratio, For photovoltaic-storage inverters Reference operating power.

[0072] It should be noted that, for power supply components, the ratio of actual total operating power to reference total operating power, i.e., the first power allocation ratio, can characterize the dynamic uncertainty in the energy conversion process. The first power allocation ratio reflects the overall matching accuracy and dynamic following capability of the power supply components during operation. This characteristic also applies to the virtualization subsystem. The dynamic matching characteristics of the virtualization subsystem and the power supply components are consistent. The actual operating power of the virtualization subsystem can be accurately calculated based on the first power allocation ratio and the reference operating power of the virtualization subsystem.

[0073] In some embodiments, determining a first power allocation ratio based on a reference total operating power and an actual total operating power may include: If the total reference operating power is less than the first power threshold, the first power allocation ratio is determined to be 1.

[0074] The first power threshold is a preset operating power threshold. When the reference total operating power of the power supply component is less than the first power threshold, it indicates that the power supply system requires the power supply component to achieve a lower expected power value (such as low load demand, insufficient input energy, etc.).

[0075] It should be noted that the first power allocation ratio is calculated based on the reference total operating power and the actual total operating power of the power supply components. The reference total operating power is used as the denominator of the first power allocation ratio. When the reference total operating power is small, the error in calculating the first power allocation ratio is large. In order to reduce the calculation error, when the reference total operating power is less than the first power threshold, the first power allocation ratio is set to 1.

[0076] In this embodiment, when the reference total operating power is less than the first power threshold, the first power allocation ratio is determined to be 1, and the actual operating power of the virtualization subsystem is equal to the reference operating power, which can effectively reduce calculation errors.

[0077] In some embodiments, after determining the actual operating power of the virtualization subsystem, the actual power loss of the virtualization subsystem is determined according to a proportional division method, including: The ratio of the absolute value of the actual operating power of the virtualization subsystem to the sum of the absolute values ​​of the actual operating power of multiple virtualization subsystems is used as the first loss allocation ratio of the virtualization subsystem. The actual power loss of the virtualization subsystem is determined based on the total actual power loss and the first power loss allocation ratio of the virtualization subsystem.

[0078] In this embodiment, the actual operating power of each virtualization subsystem can be calculated based on the first power allocation ratio and the reference operating power of each virtualization subsystem. For a certain virtualization subsystem, the ratio of the absolute value of the actual operating power of the virtualization subsystem to the sum of the absolute values ​​of the actual operating power of multiple virtualization subsystems is calculated. This ratio is used as the first loss allocation ratio of the virtualization subsystem. The actual total loss power of the power supply component is multiplied by the first loss allocation ratio of the virtualization subsystem to obtain the actual loss power of the virtualization subsystem.

[0079] For example, the power supply component is divided into n virtualized subsystems. Based on the first power allocation ratio and the reference operating power of each virtualized subsystem, the actual operating power of the n virtualized subsystems is calculated as follows: , … .

[0080] For virtualization subsystems ( =1, 2, ..., n), the formula for calculating the first loss allocation ratio is as follows:

[0081] in, For virtualization subsystem The first loss allocation ratio, For virtualization subsystem The actual operating power.

[0082] The actual total power loss of the power supply components and the virtualization subsystem First loss allocation ratio To multiply, we obtain the virtualization subsystem. The actual power loss is calculated using the following formula:

[0083] in, For virtualization subsystem The actual power loss This represents the total actual power loss of the power supply components. For virtualization subsystem The first loss allocation ratio.

[0084] In practice, the loss allocation ratio can be determined based on the reference operating power, and the actual power loss of the virtualization subsystem can be calculated.

[0085] In some embodiments, determining the actual power loss of the virtualization subsystem according to a proportional division method includes: The ratio of the absolute value of the reference operating power of the virtualization subsystem to the sum of the absolute values ​​of the reference operating power of multiple virtualization subsystems is used as the second loss allocation ratio of the virtualization subsystem. The actual power loss of the virtualization subsystem is determined based on the total actual power loss and the second power loss allocation ratio of the virtualization subsystem.

[0086] In this embodiment, for a certain virtualization subsystem, the ratio of the absolute value of the reference operating power of the virtualization subsystem to the sum of the absolute values ​​of the reference operating power of multiple virtualization subsystems is calculated. This ratio is used as the second loss allocation ratio of the virtualization subsystem. The actual total power loss of the power supply components is multiplied by the second loss allocation ratio of the virtualization subsystem to obtain the actual power loss of the virtualization subsystem.

[0087] For example, the power supply component is divided into n virtualized subsystems. The reference power information of the power supply component is obtained, which includes the reference operating power of each of the n virtualized subsystems, respectively. , … .

[0088] For virtualization subsystems ( =1, 2, ..., n), the formula for calculating the second loss allocation ratio is as follows:

[0089] in, For virtualization subsystem The second loss allocation ratio, For virtualization subsystem Reference operating power.

[0090] The actual total power loss of the power supply components and the virtualization subsystem Second loss allocation ratio To multiply, we obtain the virtualization subsystem. The actual power loss is calculated using the following formula:

[0091] in, For virtualization subsystem The actual power loss This represents the total actual power loss of the power supply components. For virtualization subsystem The second loss allocation ratio.

[0092] It should be noted that the power loss is a positive value. When calculating the power loss allocation ratio, it is calculated based on the absolute value of the actual operating power or reference operating power of the virtualization subsystem to ensure that the power loss allocated to each virtualization subsystem is positive.

[0093] In practice, the actual operating power and actual power loss of the virtualization subsystem can be calculated according to the proportional division method. For the actual operating power of the virtualization subsystem, each virtualization subsystem uses the same first power allocation ratio when calculating. For the actual power loss of the virtualization subsystem, each virtualization subsystem has its own corresponding power loss allocation ratio (first power loss allocation ratio or second power loss allocation ratio) when calculating.

[0094] II. Priority Division Method.

[0095] Understandably, the power supply components are divided into multiple virtualized subsystems, and the priority of each virtualized subsystem can be set according to the actual application scenario, control strategy, or operating mode.

[0096] In some embodiments, determining the actual operating power of the virtualization subsystem according to a priority-based approach includes: Obtain the priority of each virtualization subsystem; Based on the priority of each virtualization subsystem, the actual total operating power is allocated to at least one virtualization subsystem until the power to be allocated is 0. Determine the actual operating power of the virtualization subsystem.

[0097] In this embodiment, the priority of each virtualization subsystem is first determined. Based on the priority of each virtualization subsystem, the operating power is preferentially allocated to some virtualization subsystems in the power supply component until the actual total operating power of the power supply component is allocated, that is, the power to be allocated is 0, and the actual operating power of the virtualization subsystem can be obtained.

[0098] It is understandable that the power to be allocated is the actual total operating power of the power supply components minus the power already allocated to the virtualization subsystem.

[0099] In actual implementation, the total operating power of the power supply components is allocated to the virtualization subsystems according to the priority allocation method. There may be cases where some virtualization subsystems are not allocated power, and the actual operating power of the virtualization subsystems that are not allocated power is 0.

[0100] In some embodiments, allocating the total actual operating power to at least one virtualization subsystem according to the priority of each virtualization subsystem, until the power to be allocated is 0, includes: According to the priority of each virtualization subsystem from high to low, the corresponding reference operating power is allocated to the virtualization subsystem until the power to be allocated is 0.

[0101] In this embodiment, the actual total operating power is preferentially allocated to the highest priority virtualization subsystem. According to the reference operating power of the highest priority virtualization subsystem, the operating power is fully allocated to the highest priority virtualization subsystem. If there is still power remaining after allocation (not 0), it is allocated to the next highest priority virtualization subsystem, and the allocation is still full. This process continues until the power to be allocated is 0.

[0102] In some embodiments, determining the actual power consumption of the virtualization subsystem according to a priority-based approach includes: Obtain the priority of each virtualization subsystem; According to the priority of each virtualization subsystem, the total actual power loss is allocated to at least one virtualization subsystem until the power loss to be allocated is 0. Determine the actual power loss of the virtualization subsystem.

[0103] In this embodiment, the priority of each virtualization subsystem is first determined. Based on the priority of each virtualization subsystem, the power loss is preferentially allocated to some virtualization subsystems in the power supply component until the total actual power loss of the power supply component is allocated, that is, the power loss to be allocated is 0, and the actual power loss of the virtualization subsystem can be obtained.

[0104] It is understandable that the loss to be allocated is the total actual power loss of the power supply components minus the power loss already allocated to the virtualization subsystem.

[0105] In actual implementation, the total actual power loss of the power supply components is allocated to the virtualization subsystems according to the priority allocation method. It is possible that some virtualization subsystems will not be allocated any power loss, and the actual power loss of the virtualization subsystems that are not allocated any power loss is 0.

[0106] In some embodiments, allocating the total actual power loss to at least one virtualization subsystem according to the priority of each virtualization subsystem, until the power loss to be allocated is 0, includes: Allocate the total actual power loss to the highest priority virtualization subsystem; Among them, the actual power loss of the highest priority virtualization subsystem is equal to the total actual power loss.

[0107] In this embodiment, the virtualization subsystems are sorted from highest to lowest priority, and the total actual power loss is allocated to the virtualization subsystem with the highest priority, while the virtualization subsystems with other priorities are allocated 0 power loss.

[0108] In actual implementation, after setting the priority of each virtualization subsystem, the virtualization subsystems are sorted from high to low priority. For the allocation of the actual total operating power, the operating power is allocated in full according to the priority from high to low until the power to be allocated is 0. For the allocation of the actual total power loss, the actual total power loss is directly allocated to the virtualization subsystem with the highest priority.

[0109] Understandably, the power allocation of power supply components can be divided into allocating the actual operating power of the power supply components and allocating the actual power loss of the power supply components according to the priority allocation method. The priority of the operating power allocation of each virtualization subsystem and the priority of the power loss allocation can be the same or different.

[0110] Taking a photovoltaic-storage inverter as an example, a specific implementation is described below.

[0111] like Figure 4 As shown, the photovoltaic-storage inverter is virtually divided into three virtualized subsystems: photovoltaic-storage inverter 1, photovoltaic-storage inverter 2, and photovoltaic-storage inverter 3. The priority of operating power allocation and loss power allocation is set to be the same, and the order from high to low is: photovoltaic-storage inverter 1 > photovoltaic-storage inverter 2 > photovoltaic-storage inverter 3.

[0112] Reference operating power of photovoltaic-storage inverter 1 Reference operating power of photovoltaic-storage inverter 2 Reference operating power of photovoltaic-storage inverter 3 The actual total operating power of the photovoltaic-storage inverter The actual total power loss of the photovoltaic-storage inverter .

[0113] Regarding the allocation of the actual total operating power, based on the power allocation priority setting, the actual total operating power is first allocated to photovoltaic-storage inverter 1. The power to be allocated at this time is Then allocate the power to be allocated Allocated to photovoltaic-storage inverter 2, At this point, the power to be allocated is 0. For photovoltaic-storage inverter 3, .

[0114] Regarding the allocation of the total actual power loss, based on priority settings, all the total actual power loss is allocated to photovoltaic-storage inverter 1. The actual power loss of photovoltaic-storage inverter 1... Actual power loss of photovoltaic-storage inverter 2 Actual power loss of photovoltaic-storage inverter 3 .

[0115] It should be noted that the priority of operating power allocation and the priority of loss power allocation can be different. For example, for the allocation of the actual total loss power, the priority can be set from high to low as: photovoltaic-storage inverter 3 > photovoltaic-storage inverter 2 > photovoltaic-storage inverter 1, so that the total actual loss power is allocated to photovoltaic-storage inverter 3, and the actual loss power of photovoltaic-storage inverter 3 is... Actual power loss of photovoltaic-storage inverter 2 Actual power loss of photovoltaic-storage inverter 1 .

[0116] In practice, power deviations can be allocated based on the priority of the virtualization subsystem, and the actual operating power of the virtualization subsystem can be calculated.

[0117] In some embodiments, when there are virtualization subsystems with opposite reference operating power signs in the power supply components, the actual operating power of the virtualization subsystem is determined according to a priority allocation method, including: Obtain the power deviation value between the actual total operating power and the sum of the reference operating powers of multiple virtualization subsystems; Based on the sign of the reference operating power, multiple virtualization subsystems are divided into at least one first virtualization subsystem and at least one second virtualization subsystem, with the reference operating power signs of the first and second virtualization subsystems being opposite. Based on the priority of the virtualization subsystem, determine the power deviation allocation ratio of the first virtualization subsystem; The actual operating power of the first virtualization subsystem is determined based on the power deviation value, the power deviation allocation ratio, and the reference operating power of the first virtualization subsystem.

[0118] It should be noted that there are virtualized subsystems with opposite reference operating power signs in the power supply components. That is, at least one virtualized subsystem has a positive reference operating power sign and at least one virtualized subsystem has a negative reference operating power sign. The power supply components may have bidirectional energy flow (such as the inverter of the energy storage system).

[0119] In this embodiment, the power deviation value is first obtained as the sum of the actual total operating power of the power supply component and the reference operating power of multiple virtualization subsystems. The power deviation value represents the total power deviation between the actual operation of the power supply component and the reference target. The power deviation value is signed (positive or negative).

[0120] Meanwhile, based on the sign of the reference operating power of each virtualization subsystem, the multiple virtualization subsystems are divided into at least one first virtualization subsystem and at least one second virtualization subsystem. The first virtualization subsystem is the virtualization subsystem whose reference operating power sign is the same as (or opposite to) the power deviation value, and the second virtualization subsystem is the virtualization subsystem whose reference operating power sign is opposite to (or the same as) the power deviation value.

[0121] Based on the priority of the virtualization subsystems, the power deviation allocation ratio of the first virtualization subsystem is determined, and the power deviation value is allocated to each first virtualization subsystem according to the power deviation allocation ratio. The actual operating power of the first virtualization subsystem is equal to the difference between its own reference operating power and the allocated power deviation.

[0122] In practice, based on priority, the power deviation allocation ratio of the first virtualization subsystem with the highest (or lowest) priority can be set to 1, that is, all power deviation is allocated to the first virtualization subsystem with the highest (or lowest) priority. Alternatively, the power deviation allocation ratio of each first virtualization subsystem can be set according to the positive correlation between priority and power deviation allocation ratio.

[0123] In some embodiments, no power deviation value is assigned to the second virtualization subsystem, that is, the power deviation of the second virtualization subsystem can be calculated as 0, and the actual operating power of the second virtualization subsystem is equal to the reference operating power.

[0124] The following is a specific example.

[0125] The photovoltaic-storage inverter is virtually divided into three virtualized subsystems: photovoltaic-storage inverter 1, photovoltaic-storage inverter 2, and photovoltaic-storage inverter 3, with priority ordered from high to low as follows: photovoltaic-storage inverter 1 > photovoltaic-storage inverter 2 > photovoltaic-storage inverter 3.

[0126] Reference operating power of photovoltaic-storage inverter 1 Reference operating power of photovoltaic-storage inverter 2 Reference operating power of photovoltaic-storage inverter 3 There exists a virtualization subsystem with the opposite sign of the reference operating power.

[0127] Actual total operating power of photovoltaic-storage inverter .

[0128] The sum of reference operating power of multiple virtualization subsystems .

[0129] Power deviation value , the symbol is positive.

[0130] When the virtualization subsystem with the same sign as the power deviation value is selected as the first virtualization subsystem, the first virtualization subsystem of the power supply component includes photovoltaic-storage inverter 1 and photovoltaic-storage inverter 3. The power deviation allocation ratio of photovoltaic-storage inverter 3 is 1, and the power deviation allocated to photovoltaic-storage inverter 3 is... , combined The actual operating power of the photovoltaic-storage inverter 3 can be obtained. Meanwhile, the power deviation allocated to photovoltaic-energy storage inverter 1 and photovoltaic-energy storage inverter 2 is 0.

[0131] In this embodiment, the actual operating power of the photovoltaic-storage inverter 1 The actual operating power of the photovoltaic-storage inverter 2 The actual operating power of the photovoltaic-storage inverter 3 .

[0132] When the virtualization subsystem with the opposite sign to the power deviation value is selected as the first virtualization subsystem, the first virtualization subsystem of the power supply component includes the photovoltaic-storage inverter 2. Since there are no other first virtualization subsystems, the power deviation allocated to the photovoltaic-storage inverter 2 is... That is, the power deviation allocation ratio of the photovoltaic-storage inverter 2 is 1.

[0133] In this embodiment, the actual operating power of the photovoltaic-storage inverter 1 The actual operating power of the photovoltaic-storage inverter 2 The actual operating power of the photovoltaic-storage inverter 3 .

[0134] It should be noted that for a power supply system, the actual losses of each power supply component may not be obtainable through sensor sampling. In this case, the power or loss of the power supply system can be allocated to determine the actual power loss of each power supply component, that is, the total actual power loss of the power supply components.

[0135] In some embodiments, the power parameter determination method further includes: Based on the actual operating power of each power supply component in the power supply system, determine the total actual power loss of the power supply system. The power weighted sum of the power supply system is determined based on the absolute value of the actual operating power and the power weight of each power supply component. The third loss allocation ratio of the power supply components is determined based on the absolute value of the actual operating power, power weight, and power weighted sum of the power supply components. The actual power loss of the power supply components is determined based on the total actual power loss and the third loss allocation ratio.

[0136] In this embodiment, according to the law of conservation of energy, when the power supply system is in steady state, the total input power should be equal to the sum of the total output power and the total power loss. The actual operating power of some power supply components is included in the total input power, and the actual operating power of some power supply components is included in the total output power. Based on the actual operating power of each power supply component in the power supply system, the actual total power loss of the power supply system can be calculated.

[0137] The power weight of the power supply component is used to characterize the relative magnitude of the power loss of each power supply component. The power weight can be set to a fixed value or adjusted according to the operating conditions of the power supply component.

[0138] For example, if the power supply component is a photovoltaic panel, under normal operating conditions, the power weight of the photovoltaic panel is a1. When the voltage of the photovoltaic panel is low, the loss of the boost circuit increases significantly. The power weight of the photovoltaic panel can be increased to a2, where a2 > a1.

[0139] In this embodiment, the power weighted sum of the power supply system is calculated by weighting and summing the absolute values ​​of the actual operating power of each power supply component and its corresponding power weight.

[0140] It should be noted that the power weighted sum of the power supply system is calculated based on the absolute value of the actual operating power of each power supply component, without considering whether the power flow is input or output. Regarding the actual power carried by each power supply component, and considering the power weight, the power and losses of power supply components with higher power weights have a greater impact on the power supply system.

[0141] In this embodiment, based on the absolute value of the actual operating power of the power supply component, the power weight, and the power weighted sum, the ratio of the actual power loss of the power supply component to the total actual power loss of the power supply system, i.e., the third loss allocation ratio, can be determined. Then, by multiplying the total actual power loss of the power supply system by the third loss allocation ratio of the power supply component, the actual power loss of the power supply component can be obtained.

[0142] The following is a specific example.

[0143] like Figure 5 As shown, the photovoltaic-storage system includes a photovoltaic power generation module, an energy storage battery module, and an inverter grid-connected module, with each module corresponding to a power supply component of the power supply system.

[0144] A photovoltaic (PV) power generation module includes a photovoltaic panel and a boost circuit, which can collect the voltage and current on the PV panel side to obtain the actual operating power of the PV power generation module. (positive).

[0145] Energy storage battery modules include battery cells and DC / DC conversion circuits, which can collect cell voltage and current to obtain the actual operating power of the energy storage battery module. (Charging the battery cell is positive, discharging the battery cell is negative).

[0146] The inverter grid-connected module includes an inverter and a power grid. It can collect voltage and current data from the grid side to obtain the actual operating power of the inverter grid-connected module on the grid side. (Output to the power grid is positive, and power drawn from the power grid is negative).

[0147] In actual implementation, the actual power loss of photovoltaic power generation modules Actual power loss of energy storage battery modules and the actual power loss of the inverter grid-connected module Typically, this requires a sensor with a set sampling power.

[0148] In this embodiment, no additional sensors are required to calculate the result. , as well as .

[0149] The first step is to calculate the total actual power loss based on the input and output of the photovoltaic system. The calculation formula is as follows:

[0150] in, This represents the total actual power loss of the photovoltaic-storage system.

[0151] The second step is to calculate the weighted sum of power based on the absolute value of the actual operating power and the power weight. The calculation formula is as follows:

[0152] in, For power weighted sum, The power weights corresponding to the photovoltaic power generation modules. The power weight corresponding to the energy storage battery module. The power weight corresponding to the inverter grid-connected module. , , All are positive numbers.

[0153] The third step is to calculate the third loss allocation ratio based on the absolute value of the actual operating power of the power supply components, the power weight, and the power weighted sum.

[0154] The formula for calculating the third loss allocation ratio for photovoltaic power generation modules is as follows:

[0155] The formula for calculating the third loss allocation ratio corresponding to the energy storage battery module is as follows:

[0156] The formula for calculating the third loss allocation ratio corresponding to the inverter grid-connected module is as follows:

[0157] It is understandable that each power supply component has its own corresponding third loss allocation ratio.

[0158] The fourth step is to determine the actual power loss of the power supply components based on the total actual power loss and the third power loss allocation ratio. The calculation formula is as follows:

[0159]

[0160]

[0161] in, This represents the actual power loss of the photovoltaic power generation module. This represents the actual power loss of the energy storage battery module. This represents the actual power loss of the inverter grid-connected module.

[0162] It is understandable that, given the actual operating power, actual power loss, and reference operating power of each power supply component, the actual power parameters of each virtualization subsystem can be calculated using a proportional or priority-based allocation method.
