Its system is characterized by the integration of source storage network load. At the beginning of the system construction of a project, planning and design are required. In the system planning and design, the total power curve of the load needs to be modeled and estimated, which helps to determine the required power generation and energy storage capacity of the system. However, there are many problems with the existing system planning simulation design software. The existing system planning simulation design software usually estimates the load based on the building type and area. Although this method is relatively simple to operate, the estimation accuracy is low; some software adopts the user import method, and the user needs to input a large amount of data by himself, which is not only inefficient, but also very inconvenient for the user; some software can handle user-defined load configuration in small systems (such as home systems), but when facing large systems, such as communities and large buildings, it is difficult to conveniently configure the load.

DETAILED DESCRIPTION

[0017] In order to enable those skilled in the art to better understand the solution of the present application, 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 only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0018] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0019] See also Figure 1 This embodiment provides an energy system load modeling method, including defining standard load units according to spatial dimensions and time dimensions, and obtaining load parameters of each standard load unit; configuring load information for the load parameters of each standard load unit; establishing a power curve of each standard load unit based on the load information of each standard load unit, and then generating a total power curve of the total load unit, which solves the technical problems that the load configuration method in the prior art cannot quickly and visually configure the system load and has low data accuracy, and greatly improves the efficiency, accuracy and configurability of total load power curve modeling in project system planning and design.

[0020] In the energy system load modeling method of this embodiment, see Figure 1 , energy system load modeling methods include: S100: define standard load units according to space dimension and time dimension, and obtain load parameters of each standard load unit.

[0021] Specifically, the standard load unit is defined according to the spatial dimension and the time dimension, including: Divide the space units according to the different functions of the area, and define each divided space unit as a physical space standard load unit; In some specific embodiments, see Figure 4 ,The physical space standard load unit can be named according to the room type, e.g. Figure 4 The three-bedroom and one-living room in the figure is only for the convenience of description and understanding. For three-bedroom and one-living rooms with different orientations, floors, and distances from the fence, the time periods for the use of electrical equipment are also different. For example, air conditioners and dehumidifiers will have different usage times and frequencies according to different orientations, floors, and distances from the fence. Therefore, the division of physical space standard load units can include various forms; In some specific embodiments, the division of physical space standard load units may also include: buildings of different residential types can be defined as different physical space standard load units; for factories, they can be defined according to different standard workshop types, for example, a standard mold branch can be defined as a physical space standard load unit.

[0022] The time unit is divided according to different time periods, and each divided time unit is defined as a time standard load unit.

[0023] In some specific embodiments, the time standard load unit may include: dividing a day into different time periods, such as peak hours (7-9 am, 18-22 pm, etc., which are peak hours for household electricity consumption), normal hours (9-11 am, 14-17 pm, etc.) and off-peak hours (0-5 am, etc.). The frequency and power of electrical equipment used in different time periods are different. For example, an air conditioner may run at full load during peak hours, but basically not run during off-peak hours.

[0024] In some specific embodiments, the time standard load unit may also include: considering seasonal factors, the power load in summer and winter is very different from that in spring and autumn due to cooling or heating needs. For example, the use of heating equipment in winter will significantly increase the load in the morning and evening, while the use of air conditioning in summer will make the daytime load peak last longer.

[0025] Specifically, the method of defining the standard load unit according to the spatial dimension and the time dimension further includes: The physical space standard load unit and the time standard load unit are combined to form a standard load unit including a space dimension and a time dimension.

[0026] In some specific embodiments, the standard load units are divided from two dimensions, namely, the physical space dimension and the time dimension, to simplify the configuration process and improve the configuration efficiency under the premise of ensuring sufficient total load power curve accuracy. The standard load units should be subdivided according to the needs of planning and design simulation accuracy; It can be understood that by dividing the spatial units according to the different functions of the region, the load characteristics of different spatial areas can be reflected more accurately. This division helps to accurately obtain the load information of each spatial unit, which greatly improves the accuracy of load information acquisition; the division of the time dimension helps to accurately grasp the load information in the time dimension and enhance the flexibility of load configuration; the physical space standard load unit and the time standard load unit are combined to form a standard load unit containing space and time dimensions, so that when configuring the load, the load configuration under different space and time combinations can be flexibly adjusted according to actual needs, which improves the flexibility of load configuration and can better adapt to the needs of different scenarios.

[0027] Specifically, the load parameters of each standard load unit include: The model and quantity of each electrical equipment in each standard load unit, as well as the usage time period of each electrical equipment.

[0028] Furthermore, different types of electrical equipment may have differences in power and energy consumption characteristics. For example, the power consumption curves of LCD TVs and plasma TVs are different. Accurately recording the model helps to accurately analyze the specific contribution of each electrical equipment to the load. Understanding the model helps to consider these factors in power supply planning and equipment management. The increase or decrease in the number of electrical equipment directly affects the total load of the standard load unit. Therefore, when forecasting load, the number of electrical equipment is one of the key factors. Different electrical equipment will cause load peaks to appear at different times in different usage time periods. Understanding the usage time periods of different electrical appliances helps power companies to reasonably arrange power generation and distribution plans to cope with load peaks. By analyzing these regular usage time periods, a more accurate load model can be established to improve the operating efficiency of the power system. In summary, accurately grasping the model, quantity and usage time period of electrical equipment in each standard load unit helps to accurately analyze load contribution, plan power supply and management, cope with load peaks and valleys, and improve the operating efficiency of the power system, further ensuring the stability and efficient operation of the power system.

[0029] S200, configuring load information for load parameters of each standard load unit; Specifically, the load information of the load parameters of each standard load unit is configured, including: Receive the model and quantity of each electrical device in each standard load unit, as well as specific information of the use time period of each electrical device, input by the user in the graphical interface of the simulation software; The specific information is configured as load information of load parameters corresponding to each standard load unit.

[0030] In some specific embodiments, see Figure 4 and Figure 5 , Figure 4 The currently selected standard unit (standard load unit) is 3 bedrooms and 1 living room B, with a quantity of 10 units. The existing load part below shows "3 bedrooms and 1 living room A 10 units". Figure 5The model of the selected device is Led 15W, and the quantity is 5. The existing load part below shows "2 refrigerators". This embodiment is actually a definition example of a three-bedroom and one-living room as a standard load unit. The specific process includes: first, create a standard load unit X and name it "3 bedrooms and 1 living room B". There may be multiple three-bedroom and one-living room types, and their usage loads may be different. Multiple standard load units can be established according to actual conditions. The finer the division of the conditions considered, the more accurate the result of the total load modeling; secondly, add the first device model and quantity to the standard load unit X, and configure the device usage time mode; thirdly, add other electrical equipment in turn and complete the configuration; finally, when all electrical equipment are added, the definition of the standard load unit X is completed. The total load curve of the defined standard load unit X with time as the x-axis can be summarized and calculated at time, and the load model of the standard load unit X can be obtained.

[0031] Furthermore, by inputting the model, quantity and usage time period of the electrical equipment into the graphical interface of the simulation software, the load parameters of each standard load unit can be intuitively presented. This visual input method helps users to grasp the situation of each standard load unit as a whole. The graphical interface provides users with a convenient input method that does not require manual calculations, facilitates management and subsequent analysis, and the configuration process is presented in a graphical manner, which is convenient and easy to use, edit and save. It is also easy for users to understand and has good interpretability.

[0032] S300: Based on the load information of each standard load unit, a power curve of each standard load unit is established, and then a total power curve of the total load unit is generated.

[0033] In some specific embodiments, some attributes can also be defined for the standard load unit, such as orientation, floor, fence distance, etc., in order to correct the calculated total power load. The total load unit can be a building, and a building can include multiple standard load units. After calculating the power curve of each standard load unit separately, the power values ​​saved in each standard load unit can be directly summarized to improve the calculation efficiency.

[0034] Specifically, the power curves of the standard load units are established based on the load information of the standard load units, and then the total power curve of the total load units is generated, including: Based on the load information of each standard load unit, the power of each standard load unit is calculated according to the preset period using simulation software, and the power curve of each standard load unit within the preset period is generated. The power curves of all standard load units are summarized to generate the total power curve of the total load unit within the preset period. Through the combination method, a multi-layer and multi-granularity model can be formed, that is, a hierarchical standard load model is further constructed to improve the configuration efficiency, and finally the power curve of the total load unit is conveniently obtained.

[0035] In some specific embodiments, see Figure 6 and Figure 7 , taking a building as the total load unit as an example, configure the standard load unit combination and their respective quantities in a building, Figure 6 Based on the load information input by the user, including the effective period, cycle mode, etc., the simulation software automatically calculates and saves the total power curve of the building load according to the daily, monthly, and annual cycles. The calculation step size remains consistent and can be specifically set in the simulation software. In this embodiment, the minimum granularity of the step size can be set to 1 quarter of an hour, and the default time is 1 hour. The preset cycle in this embodiment can be set to the minimum granularity, or set to the default time, or set to daily, monthly, annually, etc., and then the standard load unit is combined to calculate its total power curve according to the daily, monthly, and annual cycles. Finally, all buildings are summarized to obtain their total power curve according to the daily, monthly, and annual cycles. In addition, the building can be further constituted into a coarser-grained composite standard load unit, and the power curves of all buildings in the project can be summarized to obtain the total load power curve that the solar storage direct and flexible system must support.

[0036] In some specific embodiments, for example, if the step length is set to 1 hour, the whole year is divided into 8760 moments, and the power value at that moment is obtained from the total power curve from moment to moment starting from 0, and whether the total load power of the energy system is equal to the power generation power of the energy system is calculated. If the step length is 15 minutes, the whole year will be divided into 8760 * 4 moments (4=1 hour / 15 minutes), starting from 0, calculate whether the total load power of the energy system is equal to the generated power of the energy system. If the calculation step is small, the calculation amount is large, and the credibility and accuracy of the simulation result are higher. On the contrary, if the calculation step is large, the calculation amount is small, and the credibility and accuracy of the simulation result will be lower. For example, for a certain standard load unit A, it runs between 00:14-00:46 every day. When the calculation step is 15 minutes, the simulation calculations at 00:14 and 00:46 will take into account the influence of the standard load unit A; when the calculation step is 1 hour, the calculations at 00:00 and 1:00 will not take into account the influence of the standard load unit A, which will affect the credibility and accuracy of the simulation results. Therefore, the step size can be selected according to the actual needs of the user, and the present invention does not further limit the value of the step size.

[0037] Furthermore, taking the preset cycle of one day and the minimum step size of 1 quarter of an hour as an example, the specific process of generating the total power curve of the total load unit in one day is explained: a project includes multiple buildings, a certain building is used as the standard load unit, the project is used as the total load unit, and a day of 24 hours is used as the basic cycle. The 24 hours are divided into 15 minutes by a calculation step, similar to the x-axis being 24 hours, with a minimum scale of 15 minutes, and the y-axis representing the load power of each building. In this way, the load of a certain building in a day can be expressed as an xy curve, and the loads of all buildings corresponding to the 00:15 scale at this time are added together to obtain the total load power value of all buildings in the project at that moment; the loads of all buildings corresponding to the 00:15 scale at this time are added together to obtain the total load power value of all buildings in the project at that moment; and so on, and finally the total load power curve of all buildings in the project for 24 hours can be obtained.

[0038] Furthermore, this embodiment uses simulation software to calculate the power of each standard load unit according to a preset period, which can achieve accurate power calculation and can intuitively present the changes in the power of each standard load unit over time. Through the power curve, the user can clearly see the time when the peak and valley values ​​of the power appear, as well as the fluctuation trend of the power within the entire preset period. This helps to deeply understand the load characteristics of each standard load unit, and summarizes the power curves of all standard load units to generate a total power curve of the total load unit within the preset period, which can achieve a comprehensive assessment of the load situation of the entire system, thereby providing a more comprehensive basis for the planning, operation and management of the power system.

[0039] In some specific embodiments, see Figure 4 , Figure 5 and Figure 6 The above figure only provides a configuration process of a graphical interface for load information. Figure 4 , Figure 5 It is completely independent, that is, there is an independent standard load unit definition function. First define the standard load unit, and then configure the building, that is, the standard load unit combination of the total load unit. Figure 4 The definition of standard load units in is embedded in the configuration with a building as the total load unit.

[0040] Specifically, the method further includes: Obtain the power generation of the energy system, determine whether the total power of the total load unit is equal to the power generation of the energy system within a preset period based on the total power curve, and determine whether the energy system is in a balanced state within the preset period based on the judgment result.

[0041] It is understandable that in the system planning and design of the project, the photovoltaic storage direct and flexible system needs to maintain power balance at all times, that is, the total load power in the system, that is, the power consumed, must be equal to the system's power generation power, so that the system is stable. For the photovoltaic storage direct and flexible system, its source is the photovoltaic array, and energy storage plays the role of energy adjustment in the system. When designing, it is necessary to perform simulation calculations according to the time step to verify whether the system is balanced at each moment. At the photovoltaic power generation end, the common minimum granularity of solar irradiance meteorological data is currently 1 hour, so it is adapted to the photovoltaic power generation end. The total power curve calculation step at the load end must reach at least the hour level. Considering the natural cycle, in the project planning and design simulation, it is generally necessary to perform a power balance and energy balance simulation for one year (8760 hours), so it is necessary to establish a total load power curve model with sufficient accuracy. By obtaining the power generation power of the energy system and comparing it with the total power of the total load unit, the balance state of the energy system within the preset cycle can be determined to ensure the stability of the photovoltaic storage direct and flexible system.

[0042] Specifically, determining whether the energy system is in a balanced state within a preset period according to the judgment result includes: If the total power of the total load unit is equal to the power generation power of the energy system within the preset period, it is determined that the energy system is in a balanced state within the preset period; If the total power of the total load unit is not equal to the power generation power of the energy system within a preset period, it is determined that the energy system is in an unbalanced state within the preset period.

[0043] It is understandable that if the total power of the total load unit is completely equal to the power generation power of the energy system at every time point during the entire preset period, the energy system is determined to be in a balanced state during this preset period. This balanced state means that the supply and consumption of energy are in a perfect matching state, the energy flow in the system is stable, and there will be no excess or shortage of energy. On the contrary, if it is found that the total power of the total load unit is not equal to the power generation power of the energy system during the preset period, there may be a problem of energy waste due to excess energy supply or insufficient energy supply that cannot meet the load demand. For example, in a photovoltaic power generation system, if the power generation power is greater than the total load power, the excess electric energy may not be effectively stored and wasted; if the power generation power is less than the total load power, some loads may not be able to operate normally. Therefore, judging the balance state of the energy system by whether the load power is equal to the power generation power can accurately judge the operating state of the energy system, help to timely discover whether there is a mismatch between energy supply and demand in the system, and provide an accurate basis for subsequent system adjustment and optimization.

[0044] It should be noted here that the present embodiment provides a method for load modeling of an energy system. First, standard load units are defined according to spatial and temporal dimensions, and load parameters of each standard load unit are obtained; then load information is configured for the load parameters of each standard load unit; based on the load information of each standard load unit, a power curve of each standard load unit is established, and then a total power curve of the total load unit is generated. The system load can be configured quickly and visually with high data accuracy, which solves the technical problem that the load configuration method in the prior art cannot configure the system load quickly and visually and has low data accuracy, and greatly improves the efficiency, accuracy and configurability of the total load power curve modeling in the project system planning and design.

[0049] Furthermore, the photovoltaic-storage-direct-flexible system is a new type of building power distribution technology that integrates multiple functions such as photovoltaic power generation (source), energy storage (storage), DC distribution (grid) and flexible electricity consumption (load). The core goal of this system is to achieve low-carbon operation and energy self-sufficiency of buildings through the efficient use of renewable energy. The application of the photovoltaic-storage-direct-flexible system can significantly improve the energy utilization efficiency of buildings, reduce dependence on traditional power grids, and also provide flexibility and stability for the power grid.

[0050] In some specific embodiments, see Figure 3 Each building is composed of multiple standard load units, namely, standard load units U1 to Un, each standard load unit is composed of electrical appliances E1 to En, and buildings B1 to Bn constitute the power load of the solar-storage direct-flexible system, that is, Figure 3 The load in the grid, together with photovoltaic power generation (source), energy storage (storage), and DC distribution (grid) form a complete photovoltaic-storage-direct-flexible system.

[0051] It should be noted here that the present embodiment provides a photovoltaic, direct-current and flexible storage device, which determines the balance state of the energy system by determining whether the load power is equal to the generated power. It can accurately judge the operating state of the energy system, and helps to promptly discover whether there is a mismatch between energy supply and demand in the system, and provide an accurate basis for subsequent system adjustment and optimization. For photovoltaic, direct-current and flexible storage devices, which need to maintain power balance at all times, accurately determining the generated power and the power of the total load unit can ensure the reasonable distribution and effective utilization of energy in the energy system, and avoid problems such as photovoltaic, direct-current and flexible storage equipment failure, energy waste or load failure due to unbalanced conditions.
