[0072] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0073] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0074] Energy storage technology is key to solving the intermittency and volatility issues of new energy sources. By configuring energy storage systems, fluctuations in new energy output can be effectively mitigated, improving the stability and reliability of the power system. Energy storage systems can absorb excess electricity during peak periods of new energy generation and release it during off-peak periods, thereby meeting the grid's load demand and reducing reliance on traditional power sources.

[0075] However, for substations that have not conventionally installed energy storage devices, directly installing such devices can easily cause significant disruptions to the existing power distribution network's regulation system, posing challenges to the overall management of the distribution network. Therefore, there is an urgent need for a technology that allows for the pre-design of energy storage devices in substations.

[0076] To address the technical problems mentioned above, the inventors, while researching the configuration method of energy storage devices in substations, discovered that by first designing the energy storage devices required for each substation in the distribution network specifically, ensuring that the energy storage devices match the actual needs of the substations, the impact of energy storage device installation on the overall distribution network can be effectively avoided. Furthermore, a reasonable energy storage device capacity design can further ensure sufficient power supply during peak hours and reduce power waste during off-peak hours during subsequent overall management of the distribution network, thereby balancing load fluctuations, improving the stability of the distribution network, and enhancing the efficiency of the entire power system.

[0077] Based on the inventors' technical concept, the substation energy storage device configuration method provided in this application first obtains historical power supply data of the substation, and then determines the type of substation and its energy storage capacity based on the obtained historical power supply data. Next, for different types of substations, different methods are used to determine the required capacity of the energy storage device based on the energy storage capacity of the substation. Finally, based on the determined required capacity of the energy storage device, the method of configuring energy storage devices for the substation is provided. This method pre-determines the required capacity of the energy storage device for each substation based on its type and energy storage capacity, thereby reducing the impact of energy storage device installation on the existing power distribution network regulation system.

[0078] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0079] Figure 1 This is a flowchart illustrating the configuration method of the energy storage device in a substation provided in Embodiment 1 of this application, as shown below. Figure 1 As shown, the method includes:

[0080] S101. Obtain historical power supply data of the substation, determine the type of the substation and its energy storage, wherein the type includes stable or fluctuating type, and the energy storage is the sum of the amount of electricity required to achieve power supply balance under the conditions of insufficient power supply and excessive power supply.

[0081] In this step, it is necessary to obtain the historical power supply data of the substation, and then perform stability analysis on the substation based on the historical power supply data to determine the type of substation. Based on the number of customers supplied with electricity recorded in the historical power supply data, the amount of electricity required for the substation to achieve power balance under insufficient power supply and the amount of electricity required to achieve power balance under excessive power supply are determined, which are used to calculate and obtain the energy storage of the substation.

[0082] Historical power supply data includes the power supply data of substations to the distribution network in the past.

[0083] In one specific implementation, historical power supply data of the substation is obtained to determine the type of the substation, including:

[0084] Step 1: Obtain the power supply data when the power supply is balanced based on historical power supply data;

[0085] Optionally, historical power supply data can be divided into power supply data during periods of insufficient power supply, power supply data during periods of balanced power supply, and power supply data during periods of excessive power supply, based on a predetermined balance standard. For example, when the data in the historical power supply data is 5% lower than the balance standard, the data is identified as power supply data during periods of insufficient power supply; when the data in the historical power supply data is 5% closer to the balance standard, the data is identified as power supply data during periods of balanced power supply; and when the data in the historical power supply data exceeds the balance standard by 5%, the data is identified as power supply data during periods of excessive power supply.

[0086] Optionally, historical load demand data can be obtained first, and then the historical power supply data and historical load demand data can be timestamped. The power supply data and load demand data at each time point can be compared. When the power supply data at a certain time point is less than the load demand data, the power supply data at that time point is determined to be the power supply data when the power supply is insufficient; when the power supply data at a certain time point is equal to the load demand data, the power supply data at that time point is determined to be the power supply data when the power supply is balanced; when the power supply data at a certain time point is greater than the load demand data, the power supply data at that time point is determined to be the power supply data when the power supply is excessive.

[0087] Step 2: Calculate the proportion of power supply data during power balance in historical power supply data;

[0088] Step 3: If the percentage is greater than or equal to the preset percentage, the substation type is determined to be stable; if the percentage is less than the preset percentage, the substation type is determined to be fluctuating.

[0089] In the above steps, it is necessary to perform stability analysis on the substation based on the proportion of the obtained power supply data during power balance in the historical data and the preset proportion. Substations with a proportion greater than or equal to the preset proportion are identified as stable, while substations with a proportion less than the preset proportion are identified as fluctuating.

[0090] The preset ratio can be determined according to the actual application, such as 80%, and this application does not limit it. For example, if the power supply data of a substation during power supply balance accounts for more than or equal to 80% of the historical power supply data, the type of the substation is determined to be stable; if the power supply data of a substation during power supply balance accounts for less than 80% of the historical power supply data, the type of the substation is determined to be fluctuating.

[0091] In this implementation, the substation type is determined by performing stability analysis based on the proportion of power supply data during power balance in historical data. This provides a basis for subsequently determining the capacity of energy storage devices for different types of substations.

[0092] In one specific implementation, historical power supply data of the substation is obtained to determine the substation's energy storage capacity, including:

[0093] Step 1: Based on historical power supply data, obtain the power supply when there is insufficient power supply, the power supply when there is excessive power supply, and the power supply when the power supply is balanced.

[0094] In this step, it is necessary to determine the power supply amount when the power supply is insufficient, the power supply amount when the power supply is excessive, and the power supply amount when the power supply is balanced, based on the power supply data divided from historical power supply data.

[0095] For example, since historical power supply data includes the power supply of substations at multiple different times, the power supply corresponding to each time in the historical power supply data can be statistically analyzed, and the average value of the power supply data when the power supply is balanced can be determined as the power supply when the power supply is balanced, the lowest value in the power supply data when the power supply is insufficient can be determined as the power supply when the power supply is insufficient, and the highest value in the power supply data when the power supply is excessive can be determined as the power supply when the power supply is insufficient.

[0096] Step 2: Determine the initial power supply required to achieve power balance based on the power supply when there is insufficient power and the power supply when there is a power balance.

[0097] In this step, the absolute value of the difference between the power supply when the power supply is insufficient and the power supply when the power supply is balanced is the first power supply required to achieve power balance.

[0098] Step 3: Determine the second power supply amount that exceeds the power supply balance based on the power supply amount when there is an oversupply and the power supply amount when the power supply is balanced.

[0099] In this step, the absolute value of the difference between the power supply when there is an oversupply and the power supply when the power supply is balanced is the second power supply required to achieve power balance.

[0100] Step 4: The sum of the first power supply and the second power supply is used as the energy storage of the substation.

[0101] In this implementation, by determining the energy storage capacity of the substation based on historical power supply data and fully considering the actual needs of the substation, the functional reliability of the energy storage equipment configured according to the energy storage capacity of the substation can be effectively guaranteed.

[0102] S102. Based on the type of substation and the energy storage capacity, determine the required capacity of the energy storage equipment for the substation.

[0103] In this step, based on the identified type of substation, a method for determining the required capacity of the energy storage equipment for that substation needs to be determined. Then, using the identified energy storage capacity of the substation, the required capacity of the energy storage equipment is determined according to the corresponding method. Here, the capacity of the energy storage equipment refers to the total electrical energy that the energy storage equipment can store.

[0104] In one specific implementation, if the substation is of the fluctuating type, then the energy storage capacity is used as the required capacity of the energy storage equipment for the substation.

[0105] Optionally, if the substation is of a stable type, the energy storage capacity can also be used as the capacity of the energy storage equipment required by the substation.

[0106] Preferably, in one specific implementation, if the substation is of a stable type, it means that the substation requires energy storage equipment relatively infrequently. Therefore, directly using the substation's stored energy as the capacity of the energy storage equipment, while meeting the substation's power supply balance requirements, may be economically unsound and fail to truly achieve cost reduction. Therefore, for stable substations, the following method can be used to determine the required capacity of the substation's energy storage equipment:

[0107] Step 1: Obtain the total cost of configuring different energy storage devices, where the energy storage capacity of different energy storage devices is a different multiple of the energy storage capacity.

[0108] In this step, based on the calculated energy storage capacity of the substation, it is necessary to identify multiple energy storage devices with different energy storage capacities and obtain the total cost required for the configuration of each energy storage device.

[0109] The total cost required for the configuration of each energy storage device includes the construction cost of the energy storage device, the operation and maintenance cost of the substation after the energy storage device is built (such as the maintenance and repair costs of the energy storage device), and daily consumption costs.

[0110] Step 2: Determine the required capacity of energy storage equipment for the substation based on the total cost of configuring different energy storage devices and the initial cost of the substation.

[0111] In this step, the required capacity of energy storage devices for stabilizing the substation needs to be determined based on the total cost of each energy storage device and the initial cost of the substation.

[0112] The initial cost of a substation refers to the daily operating costs of the substation before energy storage equipment is installed.

[0113] For example, the total cost required to configure energy storage devices with energy storage capacities of 0.5, 0.6, 0.7, 0.8, and 0.9 times the energy storage capacity can be obtained. By comparing the total cost corresponding to different energy storage devices with the initial cost of the substation, the energy storage capacity corresponding to the energy storage device with the highest economic benefits can be selected as the energy storage capacity required by the substation.

[0114] Optionally, the required energy storage capacity of the substation can be determined based on the total cost of configuring different energy storage devices and the initial cost of the substation, as follows:

[0115] If the total cost of a unique first target energy storage device is less than the initial cost, then the energy storage capacity of the first target energy storage device shall be used as the energy storage capacity required by the substation.

[0116] If the total cost of at least two energy storage devices is less than the initial cost, then based on the total cost of the at least two energy storage devices and the required labor cost, a second target energy storage device is determined from the at least two energy storage devices, and the energy storage capacity of the second target energy storage device is taken as the energy storage capacity required by the substation.

[0117] Specifically, based on the total cost of at least two energy storage devices and the required labor costs, a second target energy storage device is determined from at least two energy storage devices, including:

[0118] The reference value for each energy storage device is calculated according to the weighting formula, and the energy storage device with the smallest reference value is determined as the second target energy storage device. Specifically, the weighting formula is as follows:

[0119]

[0120] In the above formula, As a reference value, As a preset total cost weight, The total cost of energy storage equipment, The preset job number weights, The number of jobs required for energy storage equipment.

[0121] Alternatively, if the total cost of all energy storage devices exceeds the initial cost, the required capacity of the energy storage devices for the substation can be determined based on the total cost of configuring multiple energy storage devices and the initial cost of the substation, as follows:

[0122] Select the three energy storage devices with the lowest total cost from multiple energy storage devices as candidate energy storage devices; determine the target energy storage device from the candidate energy storage devices based on the energy storage capacity and required labor cost, and use the energy storage capacity of the target energy storage device as the energy storage capacity required by the substation.

[0123] The method for determining the target energy storage device from the candidate energy storage devices based on the energy storage capacity and required labor costs is the same as the method given in the previous specific implementation method, and will not be repeated here.

[0124] In this implementation, the total configuration cost required for multiple energy storage devices with storage capacities of different multiples of the energy storage capacity is first obtained. Then, based on various given scenarios, the required energy storage capacity of the substation is determined according to the total cost of configuring different energy storage devices and the initial cost of the substation. This method determines the energy storage capacity required for a stable substation. From multiple perspectives, such as the construction cost of energy storage devices, the operation and maintenance cost and daily consumption cost of the substation, as well as the number of jobs created, a cost-effectiveness analysis is conducted on energy storage devices with storage capacities of different multiples of the energy storage capacity. Finally, the required energy storage capacity of the stable substation is determined to improve the economic benefits of energy storage device construction and achieve the effect of cost reduction and efficiency improvement.

[0125] S103. Configure energy storage equipment for the substation according to the required capacity of the energy storage equipment.

[0126] In this step, the required capacity of the energy storage equipment for the substation needs to be output to the staff so that they can configure the energy storage equipment for the substation based on the output.

[0127] The method for configuring energy storage devices in substations provided in this application first obtains historical power supply data of the substation, and then determines the type of substation and its energy storage capacity based on the obtained historical power supply data. Next, for different types of substations, different methods are used to determine the required capacity of the energy storage devices for that substation based on its energy storage capacity. Finally, based on the determined required capacity of the energy storage devices for the substation, a method for configuring energy storage devices is provided. This method pre-determines the required capacity of energy storage devices for each substation based on its type and energy storage capacity, thereby reducing the impact of energy storage device installation on the original power distribution network regulation system and facilitating subsequent management of the entire power distribution network.

[0128] Furthermore, Embodiment 2 of this application provides a method for configuring energy storage devices in a substation. Based on the above embodiments, after configuring energy storage devices for the substation according to the required capacity of the energy storage devices, the method provided in this embodiment further includes:

[0129] Step 1: If a power shortage is detected at the substation, control the use of energy storage devices to connect to the grid for power supply.

[0130] Step 2: If an oversupply of power is detected at the substation, the excess power is input into the energy storage device for energy storage.

[0131] In the above steps, the power supply status of the substation is monitored, and in the event of insufficient or excessive power supply, the power supply is adjusted by energy storage equipment to achieve a power supply balance in the substation.

[0132] Optionally, by setting a minimum operating threshold for the energy storage device, which stops discharging when the device reaches the minimum operating threshold, and by setting a maximum charging threshold for the device, which stops charging the device with new energy sources when the device reaches the maximum charging threshold, the lifespan of the energy storage device can be extended, thereby improving the safety of its use and the stability of the power system.

[0133] The energy storage device configuration method for substations provided in this application monitors the power supply status of the substation. When insufficient power supply is detected, the energy storage device is controlled to be connected to the grid for power supply. When excessive power supply is detected, the excess power is input into the energy storage device for energy storage. This allows the energy storage device to charge using the excess power from the substation during off-peak hours and discharge to the substation during peak hours, thereby effectively ensuring the power supply stability of the substation and effectively improving the energy utilization efficiency of the overall power distribution network.
