[0023] The technical solutions in the embodiments of the present application will be described in detail below with reference to 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 the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of a kind and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the objects before and after are in an "or" relationship.

[0025] The new energy station refers to an energy that can reduce greenhouse gas emissions compared to traditional power supply energy (such as thermal power), such as photovoltaic power generation, wind power generation, etc. The new energy has the advantages of green and environmental protection, but due to dependence on the environment, it is greatly affected by the environment, so it also has the characteristics of unstable power generation, and often needs to be equipped with an energy storage system for adjustment to improve the utilization rate of new energy.

[0026] As shown in Figure 1 The energy storage system configuration method of the new energy station of the present application embodiment specifically includes the following steps:

[0027] Step 101, obtaining the station capacity and at least one function information of the target new energy station, the function information being used to indicate the adjustment effect of the energy storage system on the target new energy station.

[0028] Among them, at least one function information of the target new energy station corresponds to the application scenario of the target new energy station, and the application scenario of the target new energy station can be a large new energy base (denoted by N1), a supportive grid-connected new energy (denoted by N2), a market-oriented grid-connected new energy (denoted by N3), and a distributed new energy (denoted by N4). Under different application scenarios, the adjustment effect of the energy storage system of the target new energy station needs to bear is different, for example, in the supportive grid-connected new energy scenario, the adjustment effect of the energy storage system needs to bear is peak shaving performance and reducing abandoned electricity; for example, in the market-oriented grid-connected new energy scenario, the adjustment effect of the energy storage system needs to bear is frequency regulation, voltage support, and smoothing power fluctuation. It should be noted that since the adjustment effect of the energy storage system on the new energy station is different, the configuration capacity required by the energy storage system to achieve different adjustment effects is also different, therefore, according to the function information to determine the configuration capacity of the energy storage system, it can be more in line with the demand of the target new energy station.

[0029] In step 102, the target new energy station is divided into a plurality of new energy regions based on the first preset capacity, the second preset capacity, and a station capacity of the target new energy station, wherein the station capacity of each new energy region is greater than or equal to the first preset capacity and less than or equal to the second preset capacity.

[0030] In this step, the target new energy station is divided into a plurality of new energy regions according to the first preset capacity and the second preset capacity, and the station capacity of each new energy region is within the range of the first preset capacity and the second preset capacity. In the subsequent steps, each new energy region is analyzed to determine the configuration capacity of the energy storage system of each new energy region. Compared with the way of directly analyzing the entire new energy station, the difference of different new energy regions is considered, so that the energy storage system of each new energy region can meet the adjustment demand of the corresponding new energy region, and the resource waste is reduced.

[0031] In an optional embodiment, the method of dividing the target new energy station into a plurality of new energy regions further comprises:

[0032] Obtaining overall site area and density distribution information of the target new energy station;

[0033] Dividing the target new energy station into a plurality of new energy regions according to the overall site area, the density distribution information, the first preset capacity, and the second preset capacity.

[0034] Wherein, the density distribution information is obtained by: dividing the target new energy station into a plurality of unit regions based on a preset unit area and an overall site area of the target new energy station, the site area of each unit region is consistent with the preset unit area, and the density distribution information of the target new energy station can be obtained according to the number of new energy station equipment set in each unit region. The density distribution information includes a plurality of density levels, and the higher the density level, the more new energy station equipment set in the unit region corresponding to the density level.

[0035] After obtaining the density distribution information, the target renewable energy power station is divided into multiple renewable energy zones according to the density level from high to low, combined with the first and second preset capacities. For example, if the density levels include 1, 2, and 3, multiple unit zones with a density level of 3 are obtained. Then, n unit zones are randomly selected until the sum of the capacity of the power station equipment in the n unit zones is between the first and second preset capacities. These n unit zones can then be classified as a renewable energy zone. Similarly, unit zones are selected again according to the density level from high to low. If the sum of the capacity of the power station equipment in the selected unit zones is between the first and second preset capacities, the selected unit zones are classified as new renewable energy zones.

[0036] Compared to the method of dividing target new energy power stations solely based on the first and second preset capacities, the method of dividing target new energy power stations by combining density distribution information can take into account the problem of uneven distribution of power station equipment caused by environmental influences in actual application. After combining density distribution information, the distribution of power station equipment in each new energy area is relatively uniform. After confirming the configuration capacity of the energy storage system in each new energy area, the configuration capacity is evenly distributed in the new energy area, so that the allocated energy storage system will not waste resources due to excessive configuration capacity, nor will it be unable to meet the regulation needs due to insufficient configuration capacity.

[0037] Step 103: Based on at least one functional information of the energy storage system of the target new energy power station, determine at least one energy storage configuration parameter corresponding to each new energy area, wherein the energy storage configuration parameter corresponds one-to-one with the functional information.

[0038] In this step, after determining at least one functional information of the energy storage system of the target new energy power station, since the energy storage configuration capacity required to realize different functions is different, at least one corresponding energy storage configuration parameter can be determined based on at least one functional information. Since at least one functional information is the same for the new energy area and the target new energy power station, at least one energy storage configuration parameter corresponding to each new energy area is also the same as at least one energy storage configuration parameter corresponding to the target new energy power station.

[0039] Step 104: Determine the configuration capacity of the energy storage system for each new energy region based on at least one energy storage configuration parameter for each new energy region and the power station capacity for each new energy region.

[0040] For each new energy region, the product of a certain energy storage configuration parameter and the station capacity is the configuration capacity of the energy storage system required to realize the functional information corresponding to that certain energy storage configuration parameter. Based on the above relationship, the configuration capacity of the energy storage system in each new energy region can be determined.

[0041] In this embodiment, the capacity and at least one functional information of the target renewable energy power station are obtained. Based on a first preset capacity, a second preset capacity, and the capacity of the target renewable energy power station, the target renewable energy power station is divided into multiple renewable energy zones. Based on at least one functional information of the energy storage system of the target renewable energy power station, at least one energy storage configuration parameter corresponding to each renewable energy zone is determined. Based on at least one energy storage configuration parameter of each renewable energy zone and the capacity of each renewable energy zone, the configuration capacity of the energy storage system in each renewable energy zone is determined. Since the required configuration capacity of the energy storage system varies depending on the different regulatory functions required for the target renewable energy power station, determining the configuration capacity of the energy storage system based on functional information better meets the needs of the target renewable energy power station and avoids the waste of energy storage resources caused by configuring the system solely based on the capacity of the target renewable energy power station. In addition, the target renewable energy power station is divided into multiple renewable energy zones. The capacity of each renewable energy zone is within the range of the first and second preset capacities. In subsequent steps, each renewable energy zone is analyzed to determine the configuration capacity of the energy storage system in each renewable energy zone. Compared with the method of directly analyzing the entire renewable energy power station, this method takes into account the differences between different renewable energy zones, so that the energy storage system of each renewable energy zone can meet the regulation needs of the corresponding renewable energy zone and reduce resource waste.

[0042] Optionally, based on at least one functional information of the energy storage system of the target new energy power station, at least one energy storage configuration parameter corresponding to each of the new energy areas is determined, including:

[0043] Based on the power station capacity of the target new energy region, at least one functional information of the energy storage system of the target new energy region, and the output characteristics of the energy storage system corresponding to the functional information, at least one energy storage configuration parameter of the target new energy region is determined. The target new energy region is any one of the plurality of new energy regions, and at least one functional information of the energy storage system of the target new energy region is consistent with at least one functional information of the energy storage system of the target new energy power station.

[0044] In this embodiment, for different functional information, the output characteristics of the energy storage system can be detected in advance. Based on the different output characteristics of different functions, a corresponding first coefficient is set. For example, for the function of reducing power curtailment, the corresponding first coefficient is 1; for the function of peak shaving performance, the corresponding second coefficient is 1.2. Furthermore, the capacity of the target renewable energy area's power plants also affects the output characteristics of the energy storage system under different functions. Generally, if the power plant capacity exceeds a preset threshold, the output efficiency of the energy storage system will decrease. Therefore, for the power plant capacity of the target renewable energy area, a second coefficient can be set. When the power plant capacity of the target renewable energy area is less than the preset threshold, the second coefficient is 1; when the power plant capacity of the target renewable energy area exceeds the preset threshold, the second coefficient is 0.7. The product of the first coefficient and the second coefficient is determined as the energy storage configuration parameter. It can be understood that in this embodiment, by combining the energy storage system output characteristics corresponding to the functional information and the power plant capacity's output efficiency when the energy storage system achieves the adjustment effect corresponding to the functional information, the energy storage configuration parameters corresponding to the functional information of the target renewable energy area are determined. This improves the accuracy of the energy storage configuration parameters, thereby improving the accuracy of the energy storage system's configuration capacity and reducing resource waste.

[0045] Optionally, determining the configuration capacity of the energy storage system for each new energy region based on at least one energy storage configuration parameter for each new energy region and the power station capacity for each new energy region includes:

[0046] Based on at least one energy storage configuration parameter of the target new energy region and the power station capacity of the target new energy region, at least one configuration capacity of the target new energy region is determined, wherein the at least one configuration capacity of the target new energy region corresponds one-to-one with at least one energy storage configuration parameter of the target new energy region;

[0047] The maximum configuration capacity among at least one configuration capacity of the target new energy region is determined as the configuration capacity of the energy storage system of the target new energy region.

[0048] In this embodiment, based on each energy storage configuration parameter and station capacity of the target new energy area, the configuration capacity of the energy storage system corresponding to each energy storage configuration parameter can be determined, that is, the configuration capacity of the energy storage system corresponding to each functional information. The largest one is determined as the configuration capacity of the pure energy system of the target new energy area, which can ensure that the energy storage system under this configuration capacity can meet the adjustment needs corresponding to all functional information of the target new energy area, thus ensuring the stable operation of the target new energy area.

[0049] Optionally, the capacity of the target renewable energy power station is more than twice the first preset capacity. In this embodiment, the target renewable energy power station is only divided when its capacity is more than twice the first preset capacity. This avoids the problem of excessive computation caused by dividing the target renewable energy power station even when its capacity is small. For example, if the capacity of the target renewable energy power station is greater than 500,000 kilowatts, the first preset capacity is 250,000 kilowatts, and the second preset capacity is 1,000,000 kilowatts.

[0050] Optionally, the at least one functional information includes at least one of: frequency regulation, voltage support, power fluctuation smoothing, peak shaving performance, and reduced curtailment. Peak shaving performance and reduced curtailment refer to the energy storage system providing additional power support to meet demand during peak periods and storing excess power to reduce curtailment during off-peak periods through energy storage and release mechanisms. Frequency regulation refers to the energy storage system adjusting active power output to reduce frequency deviation when the frequency of the renewable energy power station deviates slightly from the target frequency. Voltage support refers to the energy storage system providing appropriate voltage according to demand in situations such as large voltage fluctuations, voltage faults at the renewable energy power station, or the need for real-time voltage regulation at the renewable energy power station, ensuring the stable operation of the renewable energy power station. Power fluctuation smoothing is similar to voltage support; the energy storage system can adjust the frequency to ensure the stable operation of the renewable energy power station. When the target renewable energy power station is a large-scale renewable energy base, at least one functional information includes frequency regulation, voltage support, power fluctuation smoothing, peak shaving performance, and reduced curtailment. When the target renewable energy power station is a guaranteed grid-connected renewable energy source, at least one functional information includes peak shaving performance and reduced curtailment. When the target renewable energy power station is a market-connected renewable energy source, at least one functional information should include frequency regulation, voltage support, and power fluctuation smoothing. When the target renewable energy power station is a distributed renewable energy source, at least one functional information should include peak-shaving performance and reduction of curtailment.

[0051] In this embodiment, in the process of configuring the capacity of the energy storage system, in addition to taking into account the conventional peak-shaving performance and reducing power curtailment, the impact of the energy storage system on the system safety and stability of the new energy power station is also taken into account, making the configuration of the energy storage system more complete and comprehensive.

[0052] Optionally, after determining the configuration capacity of the energy storage system for each new energy region based on at least one energy storage configuration parameter for each new energy region and the power station capacity for each new energy region, the method further includes:

[0053] Given that at least one functional information of the energy storage system of the target new energy power station includes the voltage support, the frequency regulation, and the smoothing of power fluctuations, obtain the frequency regulation and voltage regulation constraints of the energy storage system in the target new energy area. The target new energy area is any one of the plurality of new energy areas. The frequency regulation and voltage regulation constraints include: the restriction conditions corresponding to the reserved capacity for frequency regulation and voltage regulation, the restriction conditions corresponding to the reserved power for discharge, and the restriction conditions corresponding to the transient safety frequency.

[0054] Based on the frequency and voltage regulation constraints, the configuration capacity of the energy storage system in the target new energy area is adjusted.

[0055] In this embodiment, the frequency and voltage regulation constraints include: restrictions corresponding to the reserved capacity for frequency and voltage regulation, restrictions corresponding to the reserved power for discharge, and restrictions corresponding to the transient safe frequency. The restriction on the reserved capacity for frequency and voltage regulation means that the energy storage system needs to reserve a certain amount of capacity, and this capacity needs to be greater than the reserved capacity threshold for frequency and voltage regulation, so that the energy storage system has sufficient capacity to achieve frequency and voltage regulation. Similarly, the restrictions corresponding to the reserved power for discharge and the restrictions corresponding to the transient safe frequency correspond to the reserved power threshold for discharge and the transient safe frequency threshold, respectively, and the energy storage system needs to reserve corresponding power capacity to support frequency and voltage. It can be understood that, based on the original configured capacity of the energy storage system, the required capacity to increase the reserved capacity threshold for frequency and voltage regulation, the power capacity corresponding to the reserved power threshold for discharge, and the power capacity corresponding to the transient safe frequency threshold are increased to ensure that the energy storage system has sufficient capacity to achieve frequency and voltage regulation and guarantee the operational stability of the new energy power station.

[0056] like Figure 2 As shown in the diagram, the following provides an overall explanation of the energy storage system configuration method for new energy power plants. The target new energy power plants include N1 large-scale new energy bases, N2 guaranteed grid-connected new energy, N3 market-based grid-connected new energy, and N4 distributed new energy. For the five functional information points—1. frequency regulation, 2. voltage support, 3. power fluctuation smoothing, 4. peak-shaving performance, and 5. reduction of curtailment—each functional information corresponds to an energy storage system output characteristic. Each new energy power plant also has a corresponding energy storage system output characteristic function, denoted as φ. Nj = [i1, i2, i3, i4, i5], where i1, i2, i3, i4, and i5 represent the five functional information values ​​mentioned above. When an i value is 1, it indicates that the energy storage system of the new energy power station needs to implement the corresponding functional information indication adjustment function, and the capacity configuration of the energy storage system needs to consider the corresponding functional information. The output characteristics of the corresponding energy storage system need to be considered when calculating the capacity configuration. When i value is 0, it indicates that the energy storage system of the new energy power station does not need to implement the corresponding functional information indication adjustment function. For example, a large-scale new energy base φ N1=[1, 1, 1, 1, 1], indicating that the energy storage system of a large-scale new energy base needs to achieve the following five regulatory functions: 1. Frequency regulation; 2. Voltage support; 3. Smoothing power fluctuations; 4. Peak-shaving performance; 5. Reducing power curtailment. Guaranteed grid-connected new energy φ N2 =[0,0,0,1,1], indicating that guaranteed grid-connected renewable energy needs to achieve the regulatory effects corresponding to the two functions of 4 peak-shaving performance and 5 reduction of power curtailment. Market-based grid-connected renewable energy φ N3 =[1, 1, 1, 0, 0], Distributed new energy φ N4 =[0,0,0,1,1], the meaning of which is consistent with the above logic, and will not be repeated here.

[0057] After determining the application scenario of the target renewable energy power station, the corresponding energy storage system output characteristic function can be determined, and the target renewable energy power station φ can be... Nj Divided into multiple new energy zones (φ) N1 φ N2 φ N3 φ N4 …) After that, the output characteristic function of the energy storage system in each new energy region is the same as the output characteristic function of the target new energy power station, that is, φ Nj =φ N1 =φ N2 =φ N3 =...

[0058] Based on the output characteristic function of the energy storage system in the new energy region, at least one energy storage configuration parameter of the new energy region can be determined. Combined with the capacity of the new energy region's power station, at least one configuration capacity can be obtained. The largest configuration capacity is taken as the power station capacity of the energy storage system in the new energy region. It can be understood that the power station capacity of the energy storage system of the target new energy power station is the sum of the power station capacities of the energy storage systems in all new energy regions.
