Description

Technical Field

[0001] The present application relates to the field of electric power, and more specifically, to an energy distribution control method, device, storage medium and electronic device. Background Art

[0002] At present, the Energy Management System (EMS) with multiple energy inputs usually needs to perform complex logical judgments based on the output power of each DCDC (direct current to direct current) converter or DCAC (alternating current to direct current) converter and the target power of the load. Then, the system will modify and issue output power instructions to the corresponding converter in real time based on the output power that each DC source can provide.

[0003] However, in practice, it was found that this method has some significant problems. First, the convergence process is long. Since the power allocation of each channel needs to be adjusted frequently, the response speed of the entire system is slow, which means that the process from the initial state to the final stable state is long, reducing the overall efficiency of the system. Second, the power change is not smooth. Existing power allocation strategies often lead to frequent power fluctuations. This uneven change not only affects the stability of the system, but also causes wear and damage to the equipment. Frequent power fluctuations will cause greater pressure on the load and shorten its service life.

[0004] In summary, although the existing energy management system can manage multi-channel energy input to a certain extent, its complex logical judgment and frequent power adjustment limit the overall performance and reliability of the system. Summary of the invention

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0033] In the description of the present application, it should be noted that the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance. In addition, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0034] Based on the above statement, as introduced in the background technology, although the existing energy management system can manage multiple energy inputs to a certain extent, its complex logical judgment and frequent power adjustment problems limit the overall performance and reliability of the system.

[0035] Based on the discovery of the above technical problems, the inventors have proposed the following technical solutions to solve or improve the above problems through creative work. It should be noted that the defects in the solutions in the above prior art are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in the embodiments of the present application for the above problems below should all be the contributions made by the inventors to the present application in the process of invention and creation, and should not be understood as technical contents known to those skilled in the art.

[0036] Therefore, an embodiment of the present application provides an energy distribution control method. Figure 1 As shown, the method includes:

[0037] S1, obtain the total power actually measured by multiple DC sources in the current cycle.

[0038] S2, obtaining a power adjustment amount according to a power difference between the measured total power and the requested power of the load.

[0039] S3, adjusting the reference power of the previous cycle by using the power adjustment amount to obtain the reference power of the current cycle.

[0040] S4, obtaining the output power of each DC source in the current cycle according to the reference power of the current cycle.

[0041] In this way, by adapting to the energy demand of the load and simplifying the logical strategy of energy distribution control, the power fluctuation of the energy storage system is greatly reduced, the robustness and stability of the system are improved, and the service life of the equipment is effectively extended; moreover, the automatic balancing of the output power of multiple DC sources is achieved, ensuring that each DC source can efficiently contribute its energy according to system requirements, thereby maximizing the energy utilization of the DC source.

[0042] In addition, it should be understood that the electronic device implementing the energy distribution control method may be, but is not limited to, a custom-developed embedded device, a desktop computer, a server, and the like. The server may be a single server or a server group. The server group may be centralized or distributed (for example, the server may be a distributed system). In some embodiments, the server may be local or remote relative to the user terminal. In some embodiments, the server may be implemented on a cloud platform; by way of example only, the cloud platform may include a private cloud, a public cloud, a hybrid cloud, a community cloud, a distributed cloud, an inter-cloud, a multi-cloud, and the like, or any combination thereof. In some embodiments, the server may be implemented on an electronic device having one or more components.

[0043] To make the solution provided by this embodiment clearer, the following uses a server as an electronic device to implement the method. Figure 1 Each step of the method shown is described in detail. However, it should be understood that the operations of the flowchart may not be implemented in order, and steps without logical contextual relationships may be reversed in order or implemented simultaneously. In addition, those skilled in the art may add one or more other operations to the flowchart, or remove one or more operations from the flowchart under the guidance of the content of this application.

[0044] Continue to see Figure 1 , the method comprising:

[0045] S1, obtain the total power actually measured by multiple DC sources in the current cycle.

[0046] In an optional implementation of the present application, multiple DC sources may include any device or system that can continuously output DC power, such as wind power generation, solar power generation, etc. The power generation output by these DC sources is easily affected by many factors and therefore cannot provide stable output power. The server can be connected to multiple DC sources for communication, monitor the output power of each DC source in real time through sensors and data acquisition systems, and aggregate these data to calculate the total power of all DC sources in the current cycle. This total power reflects the actual power currently output to the load. Among them, the load can be an energy storage system in an energy storage power station or some other power-consuming equipment.

[0047] In addition, it should be understood that in the embodiment of the present application, the energy distribution control method will be periodically called at fixed time intervals. Therefore, in the embodiment of the present application, the "last cycle" refers to the previous time cycle, that is, the time period that has just ended. During this cycle, the system has collected relevant data and performed preliminary power allocation and adjustment. The "current cycle" is the time period in operation, that is, the time period in which data collection and power adjustment are being performed.

[0048] Based on the description of the multiple DC sources and the measured total power in the above embodiment, continue to refer to Figure 1 , the method further comprises:

[0049] S2, obtaining a power adjustment amount according to a power difference between the measured total power and the requested power of the load.

[0050] In the embodiment of the present application, a closed-loop control is adopted for the output power of multiple loads. Therefore, Figure 2 As shown, Figure 1 Step S2 in may include:

[0051] S2-1, obtaining the power difference between the measured total power and the requested power of the load.

[0052] S2-2, multiplying the power difference by the compensation coefficient to obtain the power adjustment amount.

[0053] In this regard, the relationship between the power difference, the compensation coefficient and the power adjustment amount can be expressed as:

[0054]

[0055] Where ΔPref represents the power adjustment amount, Pref Bat represents the requested power, n represents the number of multiple DC sources, P PVk represents the power of the kth DC source among multiple DC sources, Represents the power difference, K comp Indicates the compensation coefficient. K comp is a real number greater than 0, K comp The larger it is, the faster the adjustment is, and vice versa.

[0056] It can be understood that the server compares the total power of all DC sources actually measured with the power required by the load (such as energy storage batteries) and calculates the difference between the two, that is, the power difference. Then, based on this power difference and the pre-set compensation coefficient, the amount of power that needs to be adjusted is calculated to more accurately meet the needs of the load, thereby achieving automatic adjustment and optimal distribution of power. This adjustment mechanism can ensure that each DC source can flexibly adjust the output power according to actual needs, thereby achieving efficient operation of the entire system.

[0057] S3, adjusting the reference power of the previous cycle by using the power adjustment amount to obtain the reference power of the current cycle.

[0058] Optionally, the server may add the power adjustment amount to the reference power of the previous cycle to obtain the reference power of the current cycle. Exemplarily, assuming that the reference power of the previous cycle is represented as Pref, and the power adjustment amount is continued to be represented as ΔPref, then the reference power Pref′ of the current cycle is expressed as:

[0059] Pref′=Pref+ΔPref

[0060] In this way, the reference power of the current cycle is obtained. It can be understood that if the power difference indicates that the actual power is higher than the required power, the reference power is reduced by reducing the power adjustment amount; conversely, if the actual power is lower than the required power, the reference power is increased by increasing the power adjustment amount. The purpose of this is to make the reference power of the current cycle closer to the actual demand of the load, so as to achieve more accurate and dynamic energy allocation. This adjustment mechanism can ensure that the energy management system can make the best power allocation decision according to the actual situation in each cycle, and maintain the stability and efficiency of the system.

[0061] Based on the above description of the benchmark power, continue to refer to Figure 1 , the method further comprises:

[0062] S4, obtaining the output power of each DC source in the current cycle according to the reference power of the current cycle.

[0063] In this regard, it should be understood that during the research process, it was found that each DC source has its inherent upper and lower power limits, which are determined by the physical characteristics of the device and the operating conditions. If the output power of each DC source is determined directly according to the reference power of the current cycle, these limits may be exceeded, resulting in damage to the device or performance degradation. Therefore, if Figure 3A , 3B , 3C, in some embodiments of the present application, Figure 1 Step S4 in may include:

[0064] S4-1, for each DC source, obtaining an upper power limit and a lower power limit of the DC source.

[0065] S4-2A, if the reference power of the current cycle is greater than or equal to the upper power limit, the upper power limit of the DC source is determined as the power to be output by the DC source in the current cycle.

[0066] S4-2B, if the reference power of the current cycle is less than or equal to the power lower limit, the power lower limit of the DC source is determined as the power to be output by the DC source in the current cycle.

[0067] S4-2C, if the reference power of the current cycle is greater than the lower power limit and less than the upper power limit, the reference power of the current cycle is determined as the power to be output by the DC source in the current cycle.

[0068] In this way, the output power of each DC source is limited within its own upper and lower limit range.

[0069] In some implementations of the present application, the server needs to control the converter of each DC source by sending instructions so that each DC source outputs corresponding power. Therefore, the method also includes:

[0070] S5, for each DC source, generating a power adjustment instruction of the DC source according to the power to be output by the DC source in the current cycle.

[0071] S6, sending a corresponding power adjustment instruction to the DC source.

[0072] The power adjustment instruction is used to instruct the DC source to provide the load with the power to be output.

[0073] It can be understood that the server will generate corresponding power adjustment instructions based on the calculated output power of each DC source in the current cycle. These instructions are then sent to the converters of each DC source, instructing these converters to output electrical energy at a specific power. In this way, effective management and regulation of the output power of multiple DC sources is achieved, thereby ensuring the stable operation and efficient management of the entire system. For example, in a DC microgrid composed of multiple photovoltaic sources and energy storage batteries, the server will dynamically adjust the output power of each photovoltaic source according to the actual power demand and the output of the photovoltaic source, ensuring that the total output power of all DC sources can meet the load requirements and that the output power of each DC source remains balanced, thereby maximizing the overall efficiency and stability of the system.

[0074] In order to make the above embodiments of the present application easier to understand, the above embodiments are fully described below in conjunction with a specific example. Figure 4 The DC microgrid shown includes three solar DC sources, namely, a first DC source 11, a second DC source 12, and a third DC source 13, which are respectively represented as PV1, PV2, and PV3. Each DC source is equipped with a DCDC converter, namely, a first converter 14, a second converter 15, and a third converter 16, which are respectively represented as DCDC1, DCDC2, and DCDC3. The outputs of the three DC sources are connected in parallel to the same DC bus 17. In addition, the energy storage battery 18 as a load is also connected to the DC bus. In this way, the energy storage battery can be charged by multiple DC sources. Figure 4 The DCDC converters of the three DC sources are connected to the server 10 for communication. The server 10 calculates the current power P of the three DC sources.pv1 ,P pv2 ,P pv3 , calculate the respective output power Pref pv1 ,Pref pv2 ,Pref pv3 .

[0075] like Figure 5 As shown, in this embodiment, the energy distribution control method is called the EMS algorithm. The server 10 first initializes the output power and reference power of each DC source, and then calls the EMS algorithm according to a fixed period. Specifically, the implementation details of the EMS algorithm are as follows Figure 6 As shown, the server 10 calls the EMS algorithm to update the output power of each DC source at each fixed time period (for example, every second or every minute); that is, the measured total power P of all DC sources in the current period is obtained. pv1 +P pv2 +P pv3 Then, calculate the measured total power and the requested power Pref of the energy storage battery 18 bat The power difference between bat -(P pv1 +P pv2 +P pv3 ).

[0076] Next, the server 10 calculates the compensation coefficient K comp , calculate the power adjustment [Pref bat -(P pv1 +P pv2 +P pv3 )]×K comp ; and use the power adjustment amount to obtain the reference power of the current cycle Pref′=Pref+[Pref bat -(P pv1 +P pv2 +P pv3 )]×K comp .

[0077] Next, for each DC source PV1, PV2, PV3, the server 10 obtains the output power of each DC source according to the reference power of the current cycle and the upper and lower limits of the power of each DC source. The calculation method includes:

[0078] If the new reference power is greater than or equal to the upper power limit, the upper power limit is used as the output power to be output by the DC source.

[0079] If the new reference power is less than or equal to the power lower limit, the power lower limit is used as the output power to be output by the DC source.

[0080] If the new reference power is between the upper and lower power limits, it is used as the output power to be output by the DC source.

[0081] Finally, the server 10 generates adjustment instructions for each DC source, and sends these instructions to the converters of the corresponding DC sources, instructing them to adjust the output power.

[0082] In this way, at the beginning of system startup, some DC sources may not be able to output enough power due to the power limit, resulting in the total output power being lower than the required power of the energy storage battery. After multiple cycles of iteration, the server will gradually and automatically transfer the insufficient power demand to other DC sources that have not reached the power limit. Therefore, through multiple cycles of iteration, the insufficient power will be gradually evenly distributed to those DC sources that still have surplus. For example, assuming that PV1 has reached its power limit, and PV2 and PV3 still have surplus, the system will gradually increase the output power of PV2 and PV3 until the total power reaches the required power of the energy storage battery, thereby ensuring the thermal balance of each converter module of the same capacity to the greatest extent. In addition, it should be noted that in some cases, even if all three PVs have reached their upper limits, they still cannot meet the required power of the energy storage battery. At this time, it is also regarded as achieving the maximum utilization of the energy of the three PVs.

[0083] Based on the same inventive concept as the energy fraction control method provided in this embodiment, this embodiment also provides an energy fraction control method device. The device includes at least one software function module that can be stored in a memory or fixed in an electronic device in the form of software.

[0086] The energy sub-control module 23 is used to obtain the power to be output of each DC source in the current cycle according to the reference power of the current cycle.

[0087] In the embodiment of the present application, the power monitoring module 21 is used to implement Figure 1 In step S1, the power control module 22 is used to implement Figure 1 In steps S2 and S3, the energy sub-control module 23 is used to implement Figure 1Therefore, for the detailed description of each of the above modules, please refer to the specific implementation of the corresponding step.

[0088] In addition, it should be understood that, since the energy distribution control method has the same inventive concept as the above energy distribution control method, the energy distribution control device can also implement other steps or sub-steps of the method through the above modules.

[0095] If the reference power of the current cycle is less than or equal to the power lower limit, the power lower limit of the DC source is determined as the power to be output by the DC source in the current cycle;

[0096] If the reference power of the current cycle is greater than the lower power limit and less than the upper power limit, the reference power of the current cycle is determined as the power to be output by the DC source in the current cycle.

[0097] Optionally, the energy sub-control module is also used for:

[0098] For each DC source, generating a power adjustment instruction of the DC source according to the power to be output by the DC source in the current cycle;

[0099] A corresponding power adjustment instruction is sent to the DC source, wherein the power adjustment instruction is used to instruct the DC source to provide the load with the power to be output.
