Abstract
Description
Technical Field
[0001] Embodiments of the present invention relate to the field of power grid technology, and in particular to a power regulation method, apparatus, device and storage medium for energy storage equipment. Background Art
[0002] With the continuous growth of electricity demand and the increasing proportion of renewable energy in the energy structure, the power grid is facing new challenges in maintaining the balance between supply and demand. Especially during peak hours, due to the sharp increase in power load, the power grid needs to respond quickly to meet the instantaneous increase in demand, which puts pressure on the safe and stable operation of the power grid. In addition, the large-scale access to intermittent renewable energy such as wind power and solar energy further increases the complexity and uncertainty of power grid dispatch. In this context, energy storage equipment, as an important tool for balancing the supply and demand of the power grid, its power regulation capability is crucial to ensure the stable operation of the power system and improve energy efficiency.
[0003] However, the existing power regulation methods for energy storage devices mainly determine the target power during the peak load period of the power grid based on the rated power of the energy storage device on the user side. These methods often ignore two important problems that may occur during the actual operation process: first, during the discharge phase, if the rated power of the energy storage device exceeds the user's current actual power load, it may cause the phenomenon of "backward delivery" of electric energy to the power grid; second, during the charging phase, if the rated power of the energy storage device is much higher than the user's regular power consumption level, it may cause an increase in the user's demand electricity charge. These problems not only affect the peak load regulation effect of the power grid, but may also increase the economic burden on users.
[0004] Therefore, it is urgent to propose a new method to solve the above problems. Summary of the invention
[0005] The present invention provides a power regulation method, device, equipment and storage medium for energy storage equipment, which can ensure the peak regulation effect of the power grid while ensuring that the economic burden of users is not increased.
[0006] In a first aspect, an embodiment of the present invention provides a power regulation method for an energy storage device, comprising:
[0007] Obtaining the peak load period and peak load demand of the current area, and obtaining the equipment parameters of each user in the current area and the attribute information of the energy storage equipment of each user;
[0008] Determine a first operating power and a second operating power of each of the energy storage devices, wherein the first operating power is determined according to the rated capacity in the attribute information, and the second operating power is determined according to the device parameters;
[0009] Determine the adjustable power of each of the energy storage devices according to the rated power of each of the energy storage devices and the first operating power and the second operating power;
[0010] The total regulated power of each of the energy storage devices is obtained, and the target power of each of the energy storage devices is determined according to the total regulated power and the adjustable power of each of the energy storage devices.
[0011] The technical solution of the present invention first obtains the peak-shaving period and peak-shaving demand of the current area, and obtains the equipment parameters of each user in the current area and the attribute information of the energy storage device of each user. Then the first operating power and the second operating power of each energy storage device are determined. The determination of the first operating power can enable the energy storage device to provide the maximum charging or discharging power within a safe range, ensuring the safety and reliability of users when participating in the peak-shaving of the power grid. The determination of the second operating power ensures that during the charging stage, the charging power of the energy storage device will not be higher than the user's regular electricity consumption level, avoiding the increase in the user's demand electricity charge. And during the discharging stage, the discharge power of the energy storage device will not exceed the user's actual electricity load, avoiding the occurrence of the phenomenon of "backward delivery" of electricity to the power grid. Then, the adjustable power of each energy storage device is determined according to the rated power of each energy storage device and the first operating power and the second operating power, ensuring that the energy storage device can play the maximum utility during the peak-shaving of the power grid without causing damage to the device itself, while ensuring the user's electricity safety and economic benefits. Finally, the total regulated power of each energy storage device is obtained, and the target power of each energy storage device is determined according to the total regulated power and adjustable power of each energy storage device, thereby avoiding overload of a single energy storage device, reducing the risk of equipment failure, and improving the utilization rate of the energy storage device. Compared with the prior art, although the target power of the energy storage device during the peak-shaving period of the power grid can be determined according to the rated power of the energy storage device, this method ignores two important problems that may occur during the actual operation process: first, in the discharge stage, if the rated power of the energy storage device exceeds the user's current actual power load, it may cause the phenomenon of "backward delivery" of electric energy to the power grid; second, in the charging stage, if the rated power of the energy storage device is much higher than the user's conventional power consumption level, it may cause an increase in the user's demand electricity fee. The above problems not only affect the peak-shaving effect of the power grid, but also increase the economic burden of the user. The present invention determines the target power of each energy storage device, taking into account the physical limitations of the device (such as rated power), the actual power demand of the user and the safety requirements of the power grid, ensuring that the energy storage device can play the maximum utility during the peak-shaving of the power grid without causing damage to the device itself, while ensuring the power safety and economic benefits of the user. Therefore, the technical solution of the present invention can ensure the peak-shaving effect of the power grid while ensuring that the economic burden of users is not increased, and solves the problem of "backfeeding" electricity to the power grid and increasing user demand electricity charges.

[0038] Figure 1 A flowchart of a power regulation method for an energy storage device provided in an embodiment of the present invention. This embodiment is applicable to situations where an energy storage device is required to participate in power grid peak regulation. The method can be performed by a power regulation device of the energy storage device, and specifically includes the following steps:
[0039] Step 110: Obtain the peak load period and peak load demand of the current area, and obtain the equipment parameters of each user in the current area and the attribute information of the energy storage equipment of each user.
[0040] Among them, the peak-shaving period refers to the time period set by the power system according to actual conditions or needs in order to balance the supply and demand of the power grid. For example: 18:00-19:00 on September 18, 2024. Peak-shaving demand includes valley-filling peak-shaving and peak-shaving. Valley-filling peak-shaving refers to the storage of electricity by energy storage equipment during the low-peak period of the power grid to reduce the idle power generation and transmission resources. Peak-shaving refers to the discharge of energy storage equipment during the peak period of the power grid to reduce the load on the power grid. Equipment parameters refer to the relevant parameters of the user's power equipment, for example: equipment parameters may include historical maximum power (that is, the maximum value of the sum of the historical power consumption of all the user's power equipment in the same historical time period), user planned power (that is, the sum of the planned operating power of each power equipment of the user at the same time). Attribute information refers to the specific parameter information of the energy storage equipment, for example: attribute information includes rated capacity, rated power and planned power, etc. Energy storage equipment refers to equipment that can store and release electrical energy.
[0041] Specifically, the peak-shaving period and peak-shaving demand of the current area can be obtained from the information release platform of the smart grid system in the current area, and the attribute information of the energy storage equipment of each user in the current area and the user's planned power can be obtained through the database in the smart grid system. The power consumption data of each user in the current area within a preset time (such as one week, one month or two months, etc.) can also be obtained through the database in the smart grid system, and then the historical maximum power of each user is determined according to the power consumption data of each user in the preset time period. For example: the power consumption of each user within the preset time is obtained, and the maximum power among the power consumption of each user within the preset time is determined as the historical maximum power of each user.
[0042] In this embodiment, by obtaining the peak-shaving period, peak-shaving demand, equipment parameters of each user in the current area, and attribute information of each user's energy storage device, a data basis is provided for subsequently determining the first operating power and the second operating power of each energy storage device.
[0043] Step 120: Determine a first operating power and a second operating power of each energy storage device.
[0044] The first operating power is determined based on the rated capacity in the attribute information, that is, the maximum charging or discharging power that the energy storage device can provide within a safe range. The second operating power is determined based on the device parameters and is affected by the user's restrictions, such as the user's electricity cost.
[0045] Specifically, for each energy storage device, first determine whether the peak-shaving demand is valley-filling peak-shaving or peak-shaving peak-shaving. If the peak-shaving demand is valley-filling peak-shaving, then first determine the expected change in the amount of electricity of the energy storage device during this period, and then determine the changing load of the energy storage device based on the expected change in amount of electricity and the rated capacity of the energy storage device. Then determine the target load state of the energy storage device based on the changing load and the current state of charge of the energy storage device (that is, the percentage of the amount of electricity currently stored in the energy storage device to its rated capacity). Then, determine the target available load of the energy storage device based on the peak-shaving demand and the target load state; then determine the peak-shaving quota of the energy storage device based on the rated capacity and the target available load; and determine the first operating power of the energy storage device based on the peak-shaving quota and the peak-shaving period. Then, determine the available power based on the historical maximum power and the planned power corresponding to the energy storage device during the peak-shaving period, determine the available electricity based on the available power and the peak-shaving period, and then determine the second operating power based on the available electricity and the duration of the peak-shaving period.
[0046] If the peak-shaving demand is peak shaving, the expected change in the amount of electricity of the energy storage device during this period can be determined first. Then, based on the change in electricity and the rated capacity of the energy storage device, the change in load of the energy storage device is determined. Then, based on the change in load and the current state of charge of the energy storage device, the target load state of the energy storage device at the beginning of the peak-shaving period is determined. Then, based on the peak-shaving demand and the target load state, the target available load of the energy storage device is determined; then, based on the rated capacity and the target available load, the peak-shaving quota of the energy storage device is determined; finally, based on the peak-shaving quota and the peak-shaving period, the first operating power of the energy storage device is determined, the maximum power consumption is determined based on the historical maximum power and the peak-shaving period, and the second operating power is determined based on the maximum power consumption and the duration of the peak-shaving period.
[0047] In this embodiment, the first operating power of each energy storage device determined by the above steps can enable the energy storage device to provide the maximum charging or discharging power within a safe range, ensuring the safety and reliability of users when participating in the peak load regulation of the power grid. At the same time, the second operating power of each energy storage device determined by the above steps ensures that during the charging stage, the charging power of the energy storage device will not be higher than the user's regular power consumption level, avoiding the increase in the user's demand electricity charges. And during the discharging stage, the discharge power of the energy storage device will not exceed the user's actual power load, avoiding the occurrence of the phenomenon of "backward delivery" of electricity to the power grid.
[0048] Step 130: Determine the adjustable power of each energy storage device according to the rated power of each energy storage device and the first operating power and the second operating power.
[0049] Among them, rated power refers to the standard working power specified when the energy storage device is designed. Adjustable power refers to the power that the energy storage device can adjust during the peak load period.
[0050] Specifically, for each energy storage device, if the operating power of the energy storage device exceeds the rated power of the energy storage device, it will cause damage to the energy storage device; if the operating power of the energy storage device exceeds the first operating power of the energy storage device, the safety and reliability of the user when participating in the peak load regulation of the power grid cannot be guaranteed; if the operating power of the energy storage device exceeds the second operating power of the energy storage device, it may cause an increase in the user's demand electricity charge or the phenomenon of "backward delivery" of electricity to the power grid. Therefore, in order to avoid the above situation, the rated power of the energy storage device and the minimum value of the first operating power and the second operating power can be determined as the maximum operating power of the energy storage device during the peak load regulation period. Then, the difference between the maximum operating power of the energy storage device during the peak load regulation period and the planned operating power of the energy storage device during the peak load regulation period is calculated to obtain the adjustable power of the energy storage device.
[0051] In this embodiment, the adjustable power of each energy storage device is determined according to the rated power of each energy storage device and the first operating power and the second operating power, thereby ensuring that the energy storage device can play a maximum role during grid peak regulation without causing damage to the device itself, while ensuring the power safety and economic benefits of users.
[0052] Step 140: Obtain the total regulated power of each energy storage device, and determine the target power of each energy storage device according to the total regulated power and adjustable power of each energy storage device.
[0053] The total regulated power refers to the total power that the power system expects all energy storage devices involved in regulation to provide during the peak load period. The target power refers to the specific operating power of each energy storage device during the peak load period, determined based on the total regulated power and adjustable power of each energy storage device.
[0054] Specifically, the total regulated power of each energy storage device can be obtained from the information release platform in the smart grid system of the current area, and then the adjustable power of all energy storage devices can be sorted in order from large to small, so as to give priority to the devices with larger adjustable power, ensure that these devices play a greater role in grid regulation, and avoid waste of resources. Then, starting from the energy storage device with the largest adjustable power in the sorted list, the target power of each energy storage device is determined in turn. For each energy storage device, the target power can be determined as the sum of the adjustable power and the planned power of the device. If the total regulated power has been allocated (that is, the sum of the adjustable powers of the energy storage devices whose target powers have been determined before is greater than or equal to the total regulated power), the target power of the remaining energy storage devices is their planned power.
[0055] It should be noted that the total regulated power is less than or equal to the sum of the adjustable powers of each energy storage device.
[0056] In this embodiment, the target power of each energy storage device is determined according to the total regulated power and adjustable power of each energy storage device, thereby avoiding overload of a single energy storage device, reducing the risk of equipment failure, and improving the utilization rate of the energy storage device.
[0057] In an embodiment of the present invention, the peak-shaving period and peak-shaving demand of the current area are first obtained, and the equipment parameters of each user in the current area and the attribute information of the energy storage device of each user are obtained. Then the first operating power and the second operating power of each energy storage device are determined. The determination of the first operating power can enable the energy storage device to provide the maximum charging or discharging power within a safe range, ensuring the safety and reliability of the user when participating in the peak-shaving of the power grid. The determination of the second operating power ensures that during the charging stage, the charging power of the energy storage device will not be higher than the user's regular electricity consumption level, avoiding the increase in the user's demand electricity charge. And during the discharging stage, the discharge power of the energy storage device will not exceed the user's actual electricity load, avoiding the occurrence of the phenomenon of "backward delivery" of electricity to the power grid. Then, the adjustable power of each energy storage device is determined according to the rated power of each energy storage device and the first operating power and the second operating power, ensuring that the energy storage device can play the maximum utility during the peak-shaving of the power grid without causing damage to the device itself, while ensuring the user's electricity safety and economic benefits. Finally, the total regulated power of each energy storage device is obtained, and the target power of each energy storage device is determined according to the total regulated power and adjustable power of each energy storage device, thereby avoiding overload of a single energy storage device, reducing the risk of equipment failure, and improving the utilization rate of the energy storage device. Compared with the prior art, although the target power of the energy storage device during the peak-shaving period of the power grid can be determined according to the rated power of the energy storage device, this method ignores two important problems that may occur during the actual operation process: first, in the discharge stage, if the rated power of the energy storage device exceeds the user's current actual power load, it may cause the phenomenon of "backward delivery" of electric energy to the power grid; second, in the charging stage, if the rated power of the energy storage device is much higher than the user's conventional power consumption level, it may cause an increase in the user's demand electricity fee. The above problems not only affect the peak-shaving effect of the power grid, but also increase the economic burden of the user. The present invention determines the target power of each energy storage device, taking into account the physical limitations of the device (such as rated power), the actual power demand of the user and the safety requirements of the power grid, ensuring that the energy storage device can play the maximum utility during the peak-shaving of the power grid without causing damage to the device itself, while ensuring the power safety and economic benefits of the user. Therefore, the technical solution of the present invention can ensure the peak-shaving effect of the power grid while ensuring that the economic burden of users is not increased, and solves the problem of "backfeeding" electricity to the power grid and increasing user demand electricity charges.
[0058] Figure 2 A flowchart of another power regulation method for energy storage equipment provided by an embodiment of the present invention. This embodiment is specific based on the above embodiment. In this embodiment, the method may also include:
[0059] Step 210: Obtain the peak load period and peak load demand of the current area, and obtain the equipment parameters of each user in the current area and the attribute information of the energy storage equipment of each user.
[0060] Step 211: Determine a first operating power and a second operating power of each energy storage device.
[0061] Furthermore, the process of determining the first operating power includes: for each energy storage device, determining the target load state of the energy storage device according to the planned power and the current state of charge; determining the target available load of the energy storage device according to the peak-shaving demand and the target load state; determining the peak-shaving quota of the energy storage device according to the product of the rated capacity and the target available load; and determining the first operating power of the energy storage device according to the ratio of the peak-shaving quota to the peak-shaving period.
[0062] Among them, the attribute information of the energy storage device includes the rated capacity and the planned power. The equipment parameters include the current state of charge of the energy storage device. The planned power refers to the charging or discharging power planned for the energy storage device during normal operation. The planned power is set in advance based on the grid demand, user demand or the rated capacity of the energy storage device. For example: from 15:00 to 16:00 on September 18, 2024, if the energy storage device is planned to be charged at a power of 20 kilowatts (kw), the planned power during this time period is 20kw. From 19:00 to 20:00 on September 18, 2024, if the energy storage device is planned to be discharged at a power of 10kw, the planned power is 10kw. The current state of charge refers to the ratio between the electric energy currently stored in the energy storage device and its total capacity. For example, the current state of charge can be 50%. The target load state refers to the load state of the energy storage device at the beginning of the peak load period. The target available load refers to the available load state provided by the energy storage device during the peak load period. For example, when charging, if the target available load is 30%, it can be determined that 30% of the rated capacity of the energy storage device can be used for charging. When discharging, if the target available load is 20%, it can be determined that 20% of the rated capacity of the energy storage device can be used for discharging. The peak load quota refers to the capacity of the energy storage device that can be used for charging or the amount of electricity that can be discharged during the peak load period. For example, when charging, if the peak load quota is 100 kilowatt-hours (kWh), it can be determined that the energy storage device has a capacity of 100kWh available for charging. When discharging, if the peak load quota is 200kWh, it can be determined that the energy storage device has 200kWh of electricity available for discharging.
[0063] Specifically, for each energy storage device, the change in power of the energy storage device can be determined first, and then the ratio of the change in power and the rated capacity can be calculated to obtain the change in load of the energy storage device, and then the sum of the change in load and the current state of charge can be calculated to obtain the target load state of the energy storage device. After that, the target available load of the energy storage device can be determined according to the peak-shaving demand and the target load state. Specifically, if the peak-shaving demand is valley-filling peak-shaving, the difference between the highest state of charge (the upper limit of the chargeable amount of the energy storage device) and the target load state is calculated to obtain the target available load; if the peak-shaving demand is peak-shaving, the difference between the target load state and the lowest state of charge (the lower limit of the dischargeable amount of the energy storage device) is calculated to obtain the target available load. Then, the peak-shaving quota of the energy storage device can be determined according to the product of the rated capacity and the target available load. In practical applications, it can be determined that the peak-shaving quota of the energy storage device = rated capacity × target available load. Finally, the first operating power of the energy storage device can be determined according to the ratio of the peak-shaving quota and the peak-shaving period. In practical applications, it can be determined that the first operating power = peak-shaving quota / duration of the peak-shaving period.
[0064] In this embodiment, the first operating power is determined through the above steps, which can ensure that the energy storage device operates in the optimal state during the peak load period, thereby improving the peak load efficiency of the power grid. In addition, the process fully considers the current state of charge and rated capacity of the energy storage device, avoids damage to the device due to excessive charging and discharging, and helps to extend the service life of the energy storage device and reduce maintenance costs.
[0065] Furthermore, the target load state of the energy storage device is determined according to the planned power and the current state of charge, including: determining the changing power of the energy storage device according to the current time, planned power, and peak-shaving period; determining the changing load of the energy storage device according to the ratio of the changing power and the rated capacity; determining the target load state of the energy storage device according to the changing load and the current state of charge.
[0066] Among them, the device parameters also include the current time. The current time refers to the time when the peak-shaving period and peak-shaving demand of the current area are obtained. The variable power of the energy storage device refers to the charging or discharging power of the energy storage device from the current time to the beginning of the peak-shaving period. The variable load of the energy storage device refers to the load change of the energy storage device from the current time to the beginning of the peak-shaving period. For example: the variable load is 30%, which means that the energy storage device has charged 30% of its rated capacity during this period; the variable load is -20%, which means that the energy storage device has discharged 20% of its rated capacity during this period.
[0067] Specifically, the change in power of the energy storage device can be determined based on the current time, planned power, and peak load period. The specific calculation formula is as follows:
[0068]
[0069] Among them, A refers to the change in charge, t 0 refers to the current time, t 1 It refers to the start time of the peak load period, and P(t) refers to the planned power of the energy storage equipment.
[0070] Then, the changing load of the energy storage device is determined based on the ratio of the changing power and the rated capacity; in practical applications, the changing load of the energy storage device can be determined as changing power / rated capacity. Finally, the target load state of the energy storage device can be determined based on the changing load and the current state of charge. In practical applications, the target load state can be determined as changing load + current state of charge.
[0071] In this embodiment, through the above steps, the accuracy of determining the target load state can be improved.
[0072] Furthermore, the target available load of the energy storage device is determined according to the peak shaving demand and the target load state, including: determining the target charge boundary of the energy storage device according to the peak shaving demand and the charge boundary; when the peak shaving demand is determined to be valley filling peak shaving, determining the target available load according to the difference between the target charge boundary and the target load state; when the peak shaving demand is determined to be peak shaving, determining the target available load according to the difference between the target load state and the target charge boundary.
[0073] The attribute information also includes the charge boundary. The charge boundary refers to the minimum and maximum values allowed for the state of charge of the energy storage device during operation in order to protect the life of the energy storage device. The target charge boundary refers to the upper or lower limit of the state of charge of the energy storage device determined according to the peak load demand.
[0074] Specifically, first determine the target charge boundary of the energy storage device according to the peak-shaving demand and the charge boundary. Specifically, if the peak-shaving demand is valley-filling peak-shaving, determine the target charge boundary of the energy storage device as the maximum value in the charge boundary; if the peak-shaving demand is peak-cutting peak-shaving, determine the target charge boundary of the energy storage device as the minimum value in the charge boundary. Then, when it is determined that the peak-shaving demand is valley-filling peak-shaving, calculate the difference between the target charge boundary and the target load state to obtain the target available load; when it is determined that the peak-shaving demand is peak-cutting peak-shaving, calculate the difference between the target load state and the target charge boundary to obtain the target available load.
[0075] In this embodiment, by accurately setting the target charge boundary to calculate the target available load, the energy storage device can be helped to respond to the peak load demand of the power grid more effectively.
[0076] Furthermore, the process of determining the second operating power includes: when it is determined that the peak-shaving demand is valley-filling peak-shaving, determining the valley-filling power of the energy storage device according to the historical maximum power, the planned power, and the peak-shaving period; determining the second operating power according to the ratio of the valley-filling power and the peak-shaving period; when it is determined that the peak-shaving demand is peak-cutting peak-shaving, determining the peak-cutting power of the energy storage device according to the user's planned power and the peak-shaving period; determining the second operating power according to the ratio of the peak-cutting power and the peak-shaving period.
[0077] Among them, the equipment parameters also include the historical maximum power and the user's planned power. The historical maximum power refers to the maximum value of the sum of the historical powers of the user's various electrical equipment (such as energy storage equipment, televisions, air conditioners, etc.) in the past period of time. It is used to evaluate the user's maximum power demand during the peak-shaving period and avoid the increase of the user's demand electricity charges. The user's planned power refers to the sum of the operating power of the user's various electrical equipment (such as energy storage equipment, televisions, air conditioners, etc.) in each time period set in advance according to actual conditions or needs. It is used to determine the user's expected power demand during the peak-shaving period and help optimize the operation strategy of the energy storage equipment. The valley filling power of the energy storage device refers to the amount of power that can be charged into the energy storage device during the peak-shaving period without increasing the user's demand electricity charges. The peak shaving power of the energy storage device refers to the amount of power that can be discharged by the energy storage device during the peak-shaving period without "backfeeding power" to the power grid.
[0078] Specifically, when the peak-shaving demand is determined to be valley-filling peak-shaving, the valley-filling power of the energy storage device can be determined based on the historical maximum power, planned power, and peak-shaving period. The specific calculation formula is as follows:
[0079]
[0080] Where B represents the valley filling capacity of the energy storage device, g kmax represents the historical maximum power, and T represents the duration of the peak load period.
[0081] Then, the ratio of the valley filling power to the peak load period is calculated to obtain the second operating power.
[0082] When the peak load demand is determined to be peak load shaving, the peak load shaving capacity of the energy storage device is determined according to the user's planned power and peak load period. The specific calculation formula is as follows:
[0083]
[0084] Where C represents the peak-shaving capacity of the energy storage device, g k (t) represents the user's planned power.
[0085] Then, the ratio of the peak shaving power to the peak shaving period is calculated to obtain the second operating power.
[0086] In this embodiment, the second operating power is determined by the above steps, which can ensure that during the charging stage, the charging power of the energy storage device will not be higher than the user's normal power consumption level, thereby avoiding an increase in the user's demand electricity charges. During the discharging stage, the discharge power of the energy storage device will not exceed the user's actual power load, thereby avoiding the occurrence of "backward power supply" to the power grid.
[0087] Step 212: Determine the maximum available power of the energy storage device from the rated power of the energy storage device and the first operating power and the second operating power.
[0088] Among them, the maximum available power refers to the maximum power that the energy storage equipment can actually use during the peak load period without damaging the equipment, increasing the economic burden of users, and "backfeeding" electricity to the power grid.
[0089] Specifically, in order to ensure that the energy storage equipment is not damaged during the peak-shaving period, the economic burden on users is not increased, and there is no "backflow" of electricity to the power grid, the rated power of the energy storage equipment and the minimum value of the first operating power and the second operating power can be determined as the maximum available power of the energy storage equipment.
[0090] Step 213: Determine the planned power of the energy storage device according to the planned power and peak load period of the energy storage device.
[0091] Among them, the planned electricity refers to the total amount of electricity that the energy storage equipment plans to charge or discharge during the peak period.
[0092] Specifically, the planned power of the energy storage device can be determined according to the planned power and peak load period of the energy storage device. The specific calculation formula is as follows:
[0093]
[0094] Where D represents the planned power of the energy storage equipment.
[0095] In this embodiment, the planned power of the energy storage device is determined by the planned power and peak load period of the energy storage device, which provides a data basis for subsequently determining the average planned power of the energy storage device.
[0096] Step 214: Determine the average planned power of the energy storage device according to the planned power and peak load period.
[0097] Among them, the average planned power refers to the average power value displayed by the energy storage equipment when it is charged or discharged according to the planned power during the peak load period.
[0098] Specifically, after the planned electricity is obtained, the average planned power of the energy storage device can be determined according to the planned electricity and the peak-shaving period. Specifically, the average planned power of the energy storage device=planned electricity / duration of the peak-shaving period.
[0099] In this embodiment, the average planned power of the energy storage device is determined to determine the adjustable power of the energy storage device.
[0100] Step 215: Determine the adjustable power of the energy storage device according to the difference between the maximum available power and the average planned power.
[0101] Specifically, in practical applications, it can be determined that the adjustable power of the energy storage device = maximum available power - average planned power.
[0102] Step 216: Obtain the total regulated power of each energy storage device.
[0103] Step 217: sort the adjustable power of each energy storage device to obtain a sorting result.
[0104] Specifically, the adjustable power of each energy storage device can be sorted in descending order to obtain a sorting result, which provides a data basis for subsequently determining the required adjustable power of each energy storage device.
[0105] If there are energy storage devices with the same adjustable power, they can be sorted again in descending order according to the remaining charge and discharge times of the energy storage devices, so that devices with more remaining charge and discharge times have higher priority under the same adjustable power. This can extend the service life of the energy storage equipment while ensuring the overall peak-shaving effect.
[0106] Step 218: Determine the required power of each energy storage device according to the sorting result, the total regulated power and each adjustable power.
[0107] The required power refers to the power that each energy storage device needs to adjust during the peak load period in order to meet the peak load demand.
[0108] Specifically, after obtaining the ranking results, the total regulated power can be allocated starting from the energy storage device ranked first, that is, the required regulated power can be determined until the total allocated amount meets the total regulated power. Specifically, in order to avoid the energy storage device being unable to reach the adjustable power and affecting the peak-shaving accuracy, the required regulated power of the energy storage device can be set to k percent of the adjustable power, so as to ensure that each energy storage device can reliably provide the required power in actual operation. The required regulated power of the last allocated energy storage device is the difference between the total regulated power and the sum of the required regulated powers of the previously allocated energy storage devices, and the required regulated power of the remaining unallocated energy storage devices is 0. For example: k can be 90, 80 or 95, etc.
[0109] In this embodiment, the required regulated power of each energy storage device is determined according to the sorting result, the total regulated power and each adjustable power, which can ensure the accurate distribution of the total regulated power and maximize the peak load capacity of each energy storage device.
[0110] Step 219: Determine the target power of each energy storage device according to the required power and planned power of each energy storage device.
[0111] Specifically, in practical applications, for each energy storage device, the target power of the energy storage device can be determined as follows: the required power of the energy storage device + the planned power of the energy storage device. After determining the target power of each energy storage device, each energy storage device will be charged or discharged according to the target power during the peak-shaving period according to the peak-shaving demand. At the same time, the operating status of each energy storage device can be monitored in real time during the peak-shaving period. When the real-time power of the energy storage device deviates from the target power, an alarm can be sent to the staff's terminal so that the staff can perform subsequent processing to ensure that the energy storage device can continuously and stably participate in the peak-shaving of the power grid.
[0112] Therefore, the technical solution of the present invention first obtains the peak-shaving period and peak-shaving demand of the current area, and obtains the equipment parameters of each user in the current area and the attribute information of the energy storage device of each user. Then determine the first operating power and the second operating power of each energy storage device. The determination of the first operating power can enable the energy storage device to provide the maximum charging or discharging power within a safe range, ensuring the safety and reliability of users when participating in the peak-shaving of the power grid. The determination of the second operating power ensures that during the charging stage, the charging power of the energy storage device will not be higher than the user's regular electricity consumption level, avoiding the increase in the user's demand electricity charge. And during the discharge stage, the discharge power of the energy storage device will not exceed the user's actual electricity load, avoiding the occurrence of the phenomenon of "backward delivery" of electricity to the power grid. Then determine the maximum available power of the energy storage device from the rated power of the energy storage device and the first operating power and the second operating power to ensure that the energy storage device will not be damaged during the peak-shaving period, the economic burden of the user will not be increased, and the phenomenon of "backward delivery" of electricity to the power grid will not occur. Then, according to the planned power and peak-shaving period of the energy storage equipment, the planned electricity of the energy storage equipment is determined. Then, according to the planned electricity and peak-shaving period, the average planned power of the energy storage equipment is determined. Then, according to the difference between the maximum available power and the average planned power, the adjustable power of the energy storage equipment is determined. Then, the total regulated power of each energy storage device is obtained, and the adjustable power of each energy storage device is sorted to obtain the sorting result. According to the sorting result, the total regulated power and each adjustable power, the required regulated power of each energy storage device is determined, ensuring the accurate allocation of the total regulated power while maximizing the peak-shaving capacity of each energy storage device. Finally, according to the required regulated power and planned power of each energy storage device, the target power of each energy storage device is determined, avoiding overload of a single energy storage device, reducing the risk of equipment failure, and improving the utilization rate of the energy storage device. Compared with the prior art, although the target power of the energy storage device during the peak load period of the power grid can be determined according to the rated power of the energy storage device, this method ignores two important problems that may occur during the actual operation process: first, in the discharge stage, if the rated power of the energy storage device exceeds the current actual power load of the user, it may cause the phenomenon of "backward transmission" of electric energy to the power grid; second, in the charging stage, if the rated power of the energy storage device is much higher than the user's conventional power consumption level, it may cause an increase in the user's demand electricity fee. The above problems not only affect the peak load effect of the power grid, but also increase the economic burden of the user. The present invention determines the target power of each energy storage device, taking into account the physical limitations of the device (such as rated power), the actual power demand of the user and the safety requirements of the power grid, ensuring that the energy storage device can play the maximum utility during the peak load of the power grid without causing damage to the device itself, while ensuring the power safety and economic benefits of the user. Therefore, the technical solution of the present invention can ensure the peak load effect of the power grid while ensuring that the economic burden of the user is not increased, and solves the problem of "backward transmission" of electricity to the power grid and the increase of the user's demand electricity fee.
[0113] In addition, the first operating power of the energy storage device is determined according to the planned power, current state of charge, peak load demand and rated capacity, which can ensure that the energy storage device operates in the optimal state during the peak load period, thereby improving the peak load efficiency of the power grid. And this process fully considers the current state of charge and rated capacity of the energy storage device, avoids damage to the device due to excessive charging and discharging, helps to extend the service life of the energy storage device and reduce maintenance costs.
[0114] Moreover, the target load state of the energy storage device is determined based on the planned power, current state of charge, peak load period and rated capacity, which improves the accuracy of the determined target load state. Determining the target available load based on the peak load demand and charge boundary can help the energy storage device respond to the peak load demand of the power grid more effectively.
[0115] On the other hand, when filling the valley and shaving the peak, the second operating power is determined according to the historical maximum power, planned power, and peak-shaving period; when there is a peak-shaving demand, the second operating power is determined according to the user's planned power and peak-shaving period, which can ensure that during the charging stage, the charging power of the energy storage device will not be higher than the user's regular power consumption level, avoiding an increase in the user's demand electricity charges. During the discharge stage, the discharge power of the energy storage device will not exceed the user's actual power load, avoiding the phenomenon of "backwards" power to the grid.
