Abstract
Description
Technical Field
[0001] This application relates to the field of power regulation, and more specifically, to a method, apparatus, storage medium, and electronic device for determining power consumption strategies. Background Technology
[0002] In related technologies, multiple power supply lines (or incoming lines) with different voltage levels often exist within the same power consumption area. Each incoming line is generally connected to electrical load equipment and energy storage devices to supply power to these devices. However, in these technologies, the charging and discharging control of each incoming line is often independent, lacking a unified control system. This makes it impossible to combine the control of multiple incoming lines to achieve more effective peak shaving and valley filling, hindering the guidance of users to stagger their electricity consumption during off-peak hours, easily leading to grid instability and posing certain safety hazards. Furthermore, because the charging and discharging control of each incoming line is often independent, a failure in one incoming line will prevent the continuous supply of power to the electrical load equipment and energy storage devices connected to that line.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0025] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0026] To facilitate a better understanding of the embodiments of this application by those skilled in the art, the technical terms or some nouns that may be involved in this application are explained as follows:
[0027] A PCS (Power Conversion System) controls the charging and discharging process of a battery, converting AC to DC power, and can directly supply power to AC loads in the absence of a power grid. A PCS consists of a DC / AC bidirectional converter, a control unit, etc. The PCS controller receives control commands from the backend via communication and controls the converter to charge or discharge the battery according to the sign and magnitude of the power command, thereby regulating the active and reactive power of the power grid. The PCS controller communicates with the BMS (Battery Management System) through a CAN interface to obtain battery status information, enabling protective charging and discharging of the battery to ensure safe battery operation.
[0028] PCC (Point of Common Coupling) is the connection point between one or more user loads (electrical equipment) in a power system, and is the connection point between the power supply company and the power user.
[0029] A Battery Management System (BMS), commonly known as a battery nanny or battery manager, is primarily designed for the intelligent management and maintenance of individual battery cells. It prevents overcharging and over-discharging, extends battery life, and monitors battery status. A BMS unit includes a BMS management system, a control module, a display module, a wireless communication module, electrical equipment, a battery pack supplying power to the electrical equipment, and a data acquisition module for collecting battery information from the battery pack. The BMS management system connects to the wireless communication module and the display module via communication interfaces. The output of the data acquisition module connects to the input of the BMS management system, and the output of the BMS management system connects to the input of the control module. The control module connects to the battery pack and the electrical equipment. The BMS management system connects to the server via a wireless communication module.
[0030] According to an embodiment of this application, a method embodiment for determining an electricity consumption strategy is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.
[0031] Figure 1 This is a method for determining electricity consumption strategies according to embodiments of this application, such as... Figure 1 As shown, the method includes the following steps:
[0032] Step S102: Determine multiple incoming lines to the target area, wherein electrical load equipment and energy storage equipment are installed in the target area, and the multiple incoming lines are used to provide power to the electrical load equipment and energy storage equipment;
[0033] It should be noted that the aforementioned energy storage devices may include supercapacitors, flywheel energy storage devices, energy storage batteries, etc. Generally, energy storage devices are equipped with a BMS. The BMS is used to manage the state of the energy storage battery and to receive external commands (such as control commands from the PCS) to control the charging and discharging states of the battery.
[0034] Step S104: Determine the incoming line level of each incoming line in the multiple incoming lines. Different incoming line levels correspond to different incoming line voltages. The higher the incoming line level, the higher the corresponding incoming line voltage. The higher the incoming line voltage, the lower the electricity price.
[0035] Step S106: Determine the power consumption strategy corresponding to the target area based at least on the incoming line level. The power consumption strategy includes at least one of the following: power supply strategy for electrical load equipment and charging / discharging strategy for energy storage equipment.
[0036] The method for determining the electricity consumption strategy first identifies multiple incoming lines to a target area, where electrical loads and energy storage devices are located, and the multiple incoming lines supply power to these devices. Second, the incoming line class of each incoming line is determined, where different incoming line classes correspond to different incoming line voltages; higher incoming line classes correspond to higher incoming line voltages, and higher incoming line voltages correspond to lower electricity prices. Finally, the electricity consumption strategy for the target area is determined at least based on the incoming line classes, and the electricity consumption strategy includes at least one of the following: The power supply strategy for electrical load equipment and the charging and discharging strategy for energy storage equipment achieve the goal of rationally formulating power consumption strategies for electrical load equipment and energy storage equipment based on the different incoming line levels of multiple incoming lines in the target area. This enables unified control of electrical load equipment and energy storage equipment with multiple incoming lines, making full use of grid power and energy storage resources, and effectively ensuring the stable operation of the grid. In turn, it solves the technical problem that the lack of a unified control system for each incoming line in related technologies makes it impossible to effectively shave peaks and fill valleys, which is not conducive to guiding users to stagger their electricity consumption and is prone to causing grid instability.
[0037] It should be noted that the above method for determining the power consumption strategy can be based on a central controller. This central controller establishes a communication connection with the energy storage converter (PCS) corresponding to each incoming line, and is used to control the charging and discharging of the energy storage device through the energy storage converter. It is easy to see that the energy storage device can supply power to the electrical load equipment during the discharge process. It should also be noted that in the case of multiple energy storage batteries, for example, when each incoming line has a corresponding energy storage device, the central controller can control the charging and discharging of any one of the energy storage devices.
[0038] In some embodiments of this application, before determining the power consumption strategy corresponding to the target area based at least on the incoming line level, it is also possible to determine a first line among multiple incoming lines with an incoming line level of the first incoming line level, and a first power load device connected to the first line; determine a second line among multiple incoming lines with an incoming line level of the second incoming line level, wherein the first incoming line level is greater than the second incoming line level; and determine a second power load device connected to the second line.
[0039] For example, the first line corresponding to the first incoming line level can be a 35KV bus, and the second line corresponding to the second incoming line level can be a 10KV bus. The 35KV bus is used to supply power to the first electrical load equipment connected to it, and the 10KV bus is used to supply power to the second electrical load equipment connected to it. The 10KV bus and the 35KV bus can share the same energy storage device, or they can be connected to different energy storage devices respectively.
[0040] In some optional embodiments of this application, at least the power consumption strategy corresponding to the target area is determined based on the incoming line level. Specifically, this can be done by detecting whether the target time period is during the peak electricity price period of the second line; if the detection result indicates that the target time period is during the peak electricity price period of the second line, the energy storage device prioritizes supplying power to the second power load device and then supplies power to the first power load device; or by detecting whether the target time period is during the peak electricity price period of the first line; if the detection result indicates that the target time period is during the peak electricity price period of the first line, the energy storage device prioritizes supplying power to the first power load device and then supplies power to the second power load device.
[0041] It should be noted that during peak electricity price periods for a particular incoming line, users typically reduce their electricity consumption due to higher prices. This leads to a decrease in the load on electrical equipment, and the discharge power of the energy storage device will adaptively reduce according to the load. Therefore, the energy storage capacity of the battery cannot be fully utilized during peak electricity price periods. Taking a 35kV busbar as an example (for the first incoming line level) and a 10kV busbar as an example (for the second incoming line level), if the 10kV busbar experiences a low load during peak electricity price periods, the energy storage device will discharge at a low power to track the load. Therefore, the energy storage cannot be maximized during this period. However, the 35kV busbar may have a high load during the same time period. Therefore, this method can be used to discharge the shared battery for both buses, reducing the company's electricity costs. The same method can also be used to discharge the energy storage device when the 35kV busbar is in peak electricity price periods, which will not be elaborated further here.
[0042] Understandably, in some instances, different incoming lines may be connected to energy storage devices, i.e., there are multiple energy storage devices. However, since the central controller of this application can control the charging and discharging of any one of the energy storage devices, it is still possible to fully utilize the energy storage devices. For example, if energy storage device 1 is connected to the 10KV bus and energy storage device 2 is connected to the 35KV bus, and the 10KV bus is in a peak electricity price period, the load is very small, and the discharge power of energy storage device 1 will follow the load and discharge at a low power. Therefore, the energy storage of energy storage device 1 cannot be maximized during this period. However, the load power of 35KV may be very large during the same period. Therefore, energy storage device 1 can be used to supply power to the 35KV load equipment to reduce the electricity cost of enterprises.
[0043] If the grid-side electricity price is low, users tend to consume a large amount of electricity, leading to an increase in user-side load. However, due to the limiting effect of the transformer, the PCS cannot discharge at high power, which will affect the normal use of user-side electrical equipment. Therefore, as an optional embodiment, at least the electricity consumption strategy corresponding to the target area can be determined according to the incoming line level. It can also be to detect whether the target time period is in the low electricity price period of the second line; if the detection result indicates that the target time period is in the low electricity price period of the second line, charge the energy storage device based on the first line; or detect whether the target time period is in the low electricity price period of the first line; if the detection result indicates that the target time period is in the low electricity price period of the first line, charge the energy storage device based on the second line.
[0044] It's easy to see that, through the above method, an increase in the electrical load on one side can be offset by the incoming line on the other side, reducing its electrical load. For example, during off-peak hours when electricity prices are low, the 10kV busbar experiences high power consumption, potentially preventing the PCS on the 10kV side from charging at high power due to transformer limitations. In this case, the 35kV side may have a lower load, allowing continuous charging of the energy storage device until it is fully charged. Conversely, during off-peak hours when electricity prices are high on the 35kV side, the 10kV side can be used to charge the energy storage device.
[0045] It should be noted that if the power load on one side of the incoming line is large, the power supply to the equipment on the side with the larger load can be directly provided by the incoming line on the other side.
[0046] In some embodiments of this application, the power supply strategy corresponding to the target area is determined at least according to the incoming line level. This can also be achieved in the following way: Specifically, the operating status of each incoming line among multiple incoming lines can be detected. It should be noted that the operating status is used to indicate the power supply status of the incoming line. It can be understood that the power supply status includes normal power supply, power outage, etc. Finally, the power supply strategy corresponding to the target area can be determined according to the operating status and the incoming line level.
[0047] Specifically, determining the power supply strategy for the target area based on the operating status and incoming line level can be achieved through the following steps:
[0048] It can acquire the third incoming line that is in a power-off state among multiple incoming lines; determine the other incoming lines besides the third incoming line; determine the energy storage devices connected to the other incoming lines, as well as the third electrical load devices connected to the third incoming line; and supply power to the third electrical load devices based on the energy storage devices connected to the other incoming lines.
[0049] For example, if the 10KV busbar is found to be de-energized, the corresponding PCS may be shut down and de-energized. However, since the batteries are universal and the DC side can share the DC busbar, the energy storage device under 35KV can work normally and provide power to the 10KV load equipment, thereby increasing the effective utilization of energy storage. The same applies if the 35KV busbar is de-energized.
[0050] As mentioned above, electricity prices are generally slightly lower for higher voltage levels. If a factory has multiple incoming power lines, configuring energy storage based on these lines and performing peak-valley arbitrage operations can offer a greater arbitrage advantage than using only one incoming power line. This can promote and guide enterprises in developing reasonable customized energy storage solutions and better develop their own energy storage business projects. Therefore, in an exemplary embodiment of this application, at least the electricity consumption strategy corresponding to the target area is determined based on the incoming power line level. Furthermore, the off-peak electricity price period of the first line can be determined, during which the energy storage device is charged; and the peak electricity price period of the second line can be determined, during which the energy storage device discharges to the second electricity load device based on the peak electricity price period.
[0051] For example, a factory area has two incoming power lines of different voltage levels: 10 kV and 35 kV. The unit electricity price corresponding to these two different incoming power line voltage levels is as follows:
[0052]
[0053]
[0054] Calculations show that:
[0055] The maximum arbitrage price for peak-valley arbitrage using the 10 kV incoming line is: 1.0957 - 0.2901 = 0.8056;
[0056] The maximum arbitrage price for peak-valley arbitrage using the 35 kV incoming line is: 1.0577 - 0.2661 = 0.7916;
[0057] However, if a 35 kV incoming line is used for charging, and the load at the 10 kV incoming line is used for discharging: 1.0957 - 0.2661 = 0.8296.
[0058] Therefore, by determining the off-peak electricity price period of the first line and charging the energy storage device during the off-peak electricity price period, and by determining the peak electricity price period of the second line and discharging the energy storage device to the second electricity load device during the peak electricity price period, the maximum arbitrage can be achieved, and it can play a good role in peak shaving and valley filling for the power grid.
[0059] In some embodiments of this application, a system for determining an electricity consumption strategy is also provided, the system comprising:
[0060] The system includes multiple incoming lines, each connected to electrical load equipment. Each incoming line is equipped with an energy storage converter, which is connected to an energy storage device. The voltage of each incoming line varies; the higher the incoming line level, the higher the voltage and the lower the electricity price. A central controller is established with each energy storage converter corresponding to an incoming line for communication. This controller controls the charging and discharging of the energy storage device through the energy storage converter. Understandably, the energy storage device can supply power to the electrical load equipment during the discharging process.
[0061] It should be noted that the relationship between the incoming line and the energy storage converter can be one-to-many or one-to-one. That is, a single incoming line can be equipped with multiple energy storage converters or only one energy storage converter.
[0062] Optionally, there can be multiple energy storage devices. For example, each incoming line's corresponding energy storage converter is connected to an energy storage device. It should be noted that the energy storage converter set on each incoming line can control any one of the energy storage devices. That is, the energy storage converter set on any incoming line can control the charging and discharging of the energy storage devices connected to other energy storage converters, thereby achieving the purpose of interconnection control and realizing the technical effect of unified and coordinated control of the charging and discharging of energy storage devices.
[0063] For ease of understanding, let's consider the target area as a factory area and the multiple incoming lines as two lines in the system description. The first incoming line, corresponding to the first incoming line level, can be a 35kV busbar, and the second incoming line, corresponding to the second incoming line level, can be a 10kV busbar. Figure 2 This is a structural diagram of the system for determining the power consumption strategy in this embodiment, such as... Figure 2 As shown:
[0064] The two incoming lines are a 10kV busbar on the left and a 35kV busbar on the right. Each incoming line is equipped with a PCC and a transformer. After the voltage is converted by the transformer, it can be connected to the plant load and the PCS. Each PCS corresponds to one of the incoming lines, and the other side of the PCS is connected to an energy storage device. It can be used to control the charging and discharging of the energy storage device and to supply power to the electrical load. The dispatch and control center, i.e., the central controller, has a communication connection with the PCS corresponding to each incoming line. It is used to control the charging and discharging of the energy storage device and to supply power to the plant load through the PCS.
[0065] Figure 3 In one embodiment of this application, there are multiple energy storage devices. A schematic diagram of the system structure is shown below. Figure 3 As shown, it is similar to Figure 2The difference in the structure shown is that each incoming line's corresponding energy storage converter is connected to an energy storage device, and each incoming line's energy storage converter can control any one of the energy storage devices. It should be noted that the aforementioned energy storage devices may include supercapacitors, flywheel energy storage devices, energy storage batteries, etc. Generally, energy storage devices are equipped with a BMS (Battery Management System). The BMS is used to manage the state of the energy storage battery and to receive external commands (such as control commands from the PCS) to control the battery's charging and discharging states.
[0066] It is noteworthy that by utilizing multiple incoming circuits of different levels within the factory area, and taking advantage of the different peak-valley price differences corresponding to the different levels of incoming circuits, deep energy storage peak-valley arbitrage can be achieved. Secondly, it should be noted that battery costs account for more than 70% of the cost of energy storage equipment. Therefore, with the investment cost remaining unchanged, the technical solution of this application can use the same battery system to complete different levels of charging and discharging operations. This can not only maximize the savings in investment costs of energy storage equipment, but also maximize the electricity price difference of energy storage equipment and increase the investment rate of energy storage equipment.
[0067] Figure 4 This is an apparatus for determining an electricity consumption strategy according to an embodiment of this application, such as... Figure 4 As shown, it includes:
[0068] The first determining module 40 is used to determine the multiple incoming lines of the target area, wherein electrical load equipment and energy storage equipment are installed in the target area, and the multiple incoming lines are used to provide power to the electrical load equipment and energy storage equipment.
[0069] The second determining module 42 is used to determine the incoming line level corresponding to each incoming line in the multiple incoming lines. Different incoming line levels correspond to different incoming line voltages. The higher the incoming line level, the higher the corresponding incoming line voltage. The higher the incoming line voltage, the lower the electricity price corresponding to the incoming line voltage.

The strategy includes at least one of the following: power supply strategy for electrical load equipment and charging / discharging strategy for energy storage equipment. This achieves the goal of rationally formulating power supply strategies for electrical load equipment and energy storage equipment based on the different levels of multiple incoming lines in the target area. This enables unified control of electrical load equipment and energy storage equipment from multiple incoming lines, making full use of grid power and energy storage resources, and effectively ensuring the stable operation of the grid. Furthermore, it solves the technical problem that the lack of a unified control system for each incoming line in related technologies makes it impossible to effectively shave peaks and fill valleys, which is not conducive to guiding users to stagger their electricity consumption and easily leads to unstable grid operation.
[0072] According to another aspect of the embodiments of this application, a non-volatile storage medium is also provided, the storage medium including a stored program, wherein, when the program is running, it controls the device where the storage medium is located to execute any method for determining a power consumption strategy.

The multiple incoming lines are used to provide power to the electrical loads and energy storage devices. Determine the incoming line level for each incoming line, where different incoming line levels correspond to different incoming line voltages. The higher the incoming line level, the higher the corresponding incoming voltage, and the higher the incoming voltage, the lower the corresponding electricity price.

[0091] In the relevant embodiments of this application, a method of determining power consumption strategies based on different incoming line levels is adopted. By analyzing multiple incoming lines in the same area, the incoming line level of each incoming line and the corresponding electricity price are determined. Then, a strategy of supplying power to electrical load equipment and energy storage equipment in the same area is adopted, based at least on the incoming line level. This achieves the goal of rationally formulating power consumption strategies for electrical load equipment and energy storage equipment based on the different incoming line levels of multiple incoming lines in the target area. This enables unified control of electrical load equipment and energy storage equipment from multiple incoming lines, making full use of grid power and energy storage resources, and effectively ensuring the stable operation of the grid. This solves the technical problem that the lack of a unified control system for each incoming line in related technologies makes it impossible to effectively shaving and filling peaks, which is not conducive to guiding users to stagger their electricity consumption and easily leads to grid instability.
