Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figure 1 As shown, Figure 1 This is an architectural diagram of an energy consumption switching control system 100 provided in an embodiment of the present invention. The energy consumption switching control system 100 includes: an energy consumption switching control device 300, a server 101, and a smart energy storage inverter. The energy consumption switching control device 300 further includes a first determining module for determining the real-time operating state of a target device; a second determining module for determining a target power consumption mode of the target device based on real-time demand operation commands and the real-time operating state; and a control module for switching and / or adjusting the operating state of the target device based on the target power consumption mode.

[0019] Optionally, the target device can be a device that requires energy consumption switching control, typically a device related to energy consumption and power management, such as a smart energy storage inverter. Specifically, in this embodiment, the target device can be a smart energy storage inverter, meaning that the target device can dynamically adjust its power consumption mode based on factors such as battery energy and load demand to avoid unnecessary power consumption.

[0020] The aforementioned real-time operating status can be the current operating status information of the target device, including the device's load, power consumption, operating mode, ambient temperature, and device fault status. By monitoring the device status in real time, it is possible to ensure that the system makes correct decisions under different operating environments.

[0021] The real-time demand operation instruction refers to an instruction generated or received by the energy switching control system based on real-time environmental data, user demand, or the state of the energy switching control system during the operation of the energy switching control system, used to drive the device to perform a specific operation. These instructions are usually dynamically generated according to the actual working state of the device, load demand, external environmental changes, or user interaction behavior. Through these instructions, the energy switching control system can automatically adjust the working state or power consumption mode of the device.

[0022] The target power consumption mode can refer to the final power consumption state determined by the energy switching control system based on the real-time working state of the device and external demand instructions. Different power consumption modes correspond to different device operation behaviors, such as low power consumption mode, normal working mode, and high power consumption mode. The energy switching control system can dynamically select the appropriate power consumption mode according to the state of the target device, load demand, and other factors. Specifically, it can be divided into the following modes: Low power consumption mode: When the target device is in an idle or low load state, the system automatically selects the low power consumption mode, turning off some unnecessary functional modules to reduce the burden on the battery or power grid; Normal working mode: When the target device needs to provide normal working power, the system will keep the device in normal working mode, and the device will provide the necessary power output according to the demand; High power consumption mode: When the load demand increases, such as when the device is performing high-power discharge or charging, the system will switch to high power consumption mode to ensure that the device provides sufficient energy support.

[0023] In one possible embodiment, the energy switching control system automatically switches to low power consumption mode by monitoring the working state of the inverter in real time and meeting certain conditions. Specifically, when the inverter is in grid-connected state and there is no charge-discharge instruction, the energy switching control system determines the working state of the inverter through software. If the following conditions are met: no photovoltaic power generation (no PV), smart meter power less than 20W, inverter output power limit value less than 20W, and the state duration greater than 15 minutes, the energy switching control system sets the low power consumption mode flag to 1.

[0024] When the low power consumption mode flag is 1, the energy switching control system turns off the PWM drive signal of the inverter bridge (IGBT Q1-Q6), thereby reducing the power consumption of the inverter bridge and preventing battery energy loss due to inverter bridge control precision problems.

[0025] In low power consumption mode, when the user uses the load and takes power from the grid, the inverter will detect that the smart meter power is greater than 50W or receive a charge-discharge instruction, and the energy switching control system will immediately exit the low power consumption mode and allow the battery to supply energy to the load, with a switching time of milliseconds.

[0026] It should be noted that in the low-power mode, even if the mains power is cut off, the inverter can still provide load power for the Backup port immediately, ensuring continuous power supply of the device.

[0027] Through this method step, the above-mentioned energy consumption switching control system can flexibly respond to changes in device load and external demand, realize efficient energy management, and maximize user economic benefits and device energy efficiency.

[0028] In another possible embodiment, the above-mentioned energy consumption switching control system monitors the working state of the target device in real time, and determines the target power consumption mode of the target device based on real-time demand operation instructions and working state data, and switches or controls the target device according to the determined power consumption mode, realizing dynamic energy efficiency optimization. In different situations such as load change, sufficient or insufficient battery power, etc., the above-mentioned energy consumption switching control system can adaptively adjust the power consumption mode of the target device to ensure efficient operation of the target device and prolong the service life, thereby realizing energy saving and improving energy utilization efficiency.

[0029] As shown in Figure 2 , the flowchart of the energy consumption switching control method provided by the embodiment of the present application comprises the following steps: Figure 2 201, determining the real-time working state of the target device.

[0030] In the embodiment of the present application, the above-mentioned energy consumption switching control method can be applied to the above-mentioned energy consumption switching control system, which has functions of energy consumption data processing, energy consumption data transceiving and energy consumption data storage, and can be constructed based on a server or a server cluster. The above-mentioned server or server cluster can be an electronic device with energy consumption data processing capability.

[0031] The above-mentioned target device can be a device that needs to be controlled by energy consumption switching, which is usually a device related to energy consumption and power management, for example, a smart energy storage inverter. Specifically, in the present embodiment, the above-mentioned target device can be a smart energy storage inverter, i.e. the target device can dynamically adjust its power consumption mode according to the energy of the battery, load demand and other factors, to avoid unnecessary power consumption.

[0032] The above-mentioned real-time working state can be the current running state information of the above-mentioned target device, including the load, power consumption, working mode, environment temperature, device fault state, etc. of the device. By monitoring the device state in real time, it can be ensured that the system makes correct decisions in different working environments.

[0033] ​In one possible embodiment, the energy consumption switching control system monitors the operating state of the target device in real time through sensors. For example, for a smart energy storage inverter, the system monitors parameters such as load current, battery power, device temperature, etc. Through these data, the system can accurately determine the current working state of the device, such as whether it is in a high load, low load, standby state, etc.

[0034] The energy consumption switching control system can also determine whether to switch the power consumption mode according to the real-time working state of the device. For example, when the load power is low and the battery power is sufficient, the system will switch the target device to a low power consumption mode to reduce energy consumption.

[0035] 202. Based on the real-time demand operation instruction and the real-time working state, determine the target power consumption mode of the target device.

[0036] In the embodiments of the present application, the real-time demand operation instruction refers to the instruction generated or received by the energy consumption switching control system during operation, based on real-time environmental data, user demand or the state of the energy consumption switching control system, for driving the device to perform specific operations. These instructions are usually dynamically generated according to the actual working state of the device, load demand, external environmental changes or user interaction behavior.

[0037] The target power consumption mode can refer to the final power consumption state determined by the energy consumption switching control system according to the real-time working state of the device and external demand instructions. Different power consumption modes correspond to different device operation behaviors, such as low power consumption mode, normal working mode and high power consumption mode. The energy consumption switching control system can dynamically select the appropriate power consumption mode according to the state of the target device, load demand, etc. Specifically, it can be divided into the following modes: Low power consumption mode: when the target device is in an idle or low load state, the system automatically selects a low power consumption mode, turns off some unnecessary functional modules, and reduces the burden on the battery or power grid; Normal working mode: when the target device needs to provide normal working power, the system will keep the device in normal working mode, and the device will provide the necessary power output according to the demand; High power consumption mode: when the load demand increases, such as when the device is discharging or charging at high power, the system will switch to a high power consumption mode to ensure that the device provides sufficient energy support.

[0038] In a possible embodiment, the energy consumption switching control system intelligently adjusts the power consumption mode of the target device through real-time working state of the target device and real-time demand operation instruction. Specifically, the running state data of the device is monitored in real time. These data can include load current, battery level, temperature, environmental sensor data, etc. of the device. Through these data, the working state of the device can be accurately judged. For example, the battery level of the target device is 70%, the load power is 30W, and the temperature is 25℃. According to the external or generated real-time demand operation instruction such as “switch to low power consumption mode” or “increase power output”, when the device detects that the user sends the instruction of “switch to low power consumption mode” on the APP, whether to enter the low power consumption mode is judged in combination with the current working state (such as load power and battery level) of the device.

[0039] In the embodiment, if the load of the target device is low and the battery level is sufficient, the energy consumption switching control system selects the low power consumption mode; if the load is high and the battery level is insufficient, the energy consumption switching control system selects the high power consumption mode to ensure that the device provides sufficient power output.

[0040] If the target power consumption mode is the low power consumption mode, the control module will turn off the unnecessary functional components (such as the battery charging module), and reduce the power consumption of the device to the preset energy consumption value.

[0041] For example, in the low power consumption mode, the control module will turn off the battery charging function and only maintain the basic work of the device; and in the high power consumption mode, the system will enhance the power output and provide higher power support.

[0042] Through the above method steps, the power consumption mode can be dynamically adjusted under different loads and environmental conditions, the energy use is optimized, the energy waste is reduced, and the service life of the device is prolonged.

[0043] 203、based on the target power consumption mode, the working state of the target device is switched and / or controlled and adjusted.

[0044] In the embodiment of the application, the energy consumption switching control system intelligently determines the power consumption mode of the target device by monitoring the working state of the device in real time and combining the real-time demand operation instruction. According to the determined target power consumption mode, the power consumption switching operation is performed: in the low power consumption mode, the system automatically turns off the unnecessary functional components and reduces the power consumption; in the high power consumption mode, the system improves the power output to ensure that the device demand is met. Through this process, the system can flexibly cope with different working states and external demand changes, maximize the energy efficiency of the device, and reduce energy waste.

[0045] Optionally, in the step of determining the real-time working state of the target device, further comprising: collecting current working data of the target device in real time; and identifying the grid-connected state, power data and pre-execution instruction of the target device based on preset software to determine the real-time working state of the target device.

[0046] In the embodiment of the present application, the working data can include, but is not limited to, the grid-connected state, power data and pre-execution instruction of the target device.

[0047] The preset software can be a program or algorithm written in advance and deployed on the target device, used for real-time monitoring and analyzing the running state of the target device. The preset software can process the collected data through a set of logic and rules, and adjust the power consumption mode of the device according to the working conditions and demand instructions of the target device. In the embodiment, the preset software can be responsible for real-time identification of the working state (such as the grid-connected state, power data, etc.) of the target device, to ensure reasonable switching of the power consumption mode under different conditions.

[0048] The current working data can include state information of the target device at a certain moment, mainly including the grid-connected state, power data and pre-execution instruction, etc. The grid-connected state indicates whether the device has been connected to the power grid, the power data indicates the current power output or consumption of the device, and the pre-execution instruction is the operation instruction to be executed in the future (such as whether to start the low-power consumption mode). These data are used to describe the real-time running state of the device.

[0049] The real-time working state can be the current operation mode and power consumption state of the target device. In the present application, the real-time working state can include "low-power consumption mode" and "power supply mode". The low-power consumption mode means that the device is in standby or idle state, with the lowest power consumption; the power supply mode means that the device is in working state, providing power output.

[0050] In a possible embodiment, the energy consumption switching control system analyzes and interprets the working data (such as the grid-connected state, power data, pre-execution instruction, etc.) collected in real time through the preset software, determines the current working state of the target device, and makes corresponding operation decisions based thereon.

[0051] Specifically, the working data of the target device is collected in real time, including the grid-connected state, power data and pre-execution instruction. Assuming that the target device is running in the grid-connected state, and its power consumption is 100W, and the pre-execution instruction is to switch to the low-power consumption mode, the preset software receives these data and starts the identification processing flow: Identify the grid-connected state: the device is connected to the power grid, and no charge-discharge instruction is received; Identify the power data: the current power consumption is 100W; Identifying pre-execution instruction: the system receives an instruction to switch to a low-power mode; the software compares the working data and finds that the power data is low and the system instruction requires switching to a low-power mode.

[0052] Therefore, the preset software switches the working state of the target device to a low-power mode, and when the target device switches to the low-power mode, the system turns off unnecessary function modules such as the battery charging module, and ensures that the power consumption is reduced to a preset energy consumption value.

[0053] Optionally, in the step of determining the target power consumption mode of the target device based on the real-time demand operation instruction and the real-time working state, the step comprises: analyzing the real-time demand operation instruction to determine working change data corresponding to the operation; comparing the working data corresponding to the real-time working state based on the working change data to determine target working data; and determining the target power consumption mode of the target device based on the target working data.

[0054] In the embodiments of the present application, the real-time demand operation instruction can be analyzed by a preset algorithm or rule. Specifically, the key information (such as which working mode needs to be switched to, whether the power consumption needs to be adjusted, etc.) in the instruction can be understood and extracted, and corresponding operation instructions or working data can be generated according to the information. The target working data required by the instruction can also be directly switched, such as the power required.

[0055] The above working change data can be obtained by analyzing the real-time demand operation instruction, and represents specific data of operation change. Specifically, the above working change data can generally include but is not limited to detailed information related to the working state change of the target device, such as the conditions and values required for operations such as switching to a low-power mode and increasing power output. Generally, it can represent the changes required from the current working state to the target working state.

[0056] In one possible embodiment, the above energy consumption switching control system compares the real-time working state data and the working change data to determine whether operation is required. It can be understood that the purpose of comparison is to find the difference between the current state of the target device and the state required to be changed, and to determine whether the switching condition is met. If the comparison result shows that the change is required, the above energy consumption switching control system will take corresponding action.

[0057] The above target working data can be the result of comparison, which describes the working state that the device should be in under the target power consumption mode. Generally, it can include but is not limited to specific parameters (such as power, load, running mode, etc.) of the target device in the new state, and is used to guide the control module on how to adjust the target device to achieve the target power consumption mode.

[0058] Optionally, the step of comparing the work data corresponding to the real-time work status based on the work change data to determine the target work data further includes: comparing the work change data with the work data corresponding to the real-time work status to determine the comparison result; determining a correction instruction to correct the corresponding work data based on the comparison result; and modifying the work data corresponding to the real-time work status based on the correction instruction to obtain the target work data.

[0059] In this embodiment of the invention, the difference between the current working state and the target working state can be determined by comparing real-time working status data with working change data item by item, thereby identifying the areas that need adjustment and providing a basis for decision-making in subsequent operations.

[0060] The comparison results mentioned above can refer to the differences or matches obtained by comparing the work data corresponding to the real-time work status with the work change data.

[0061] The aforementioned correction command can refer to an instruction generated by the energy consumption switching control system based on the comparison results and the difference between the current operating state and the target state, used to correct the operating state or adjust the operating data. It can be understood that the aforementioned correction command is the specific step in the energy consumption switching control system performing the adjustment operation, typically involving modification or manipulation of the operating data.

[0062] In one possible embodiment, the aforementioned energy consumption switching control system compares real-time operating status with operating change data to determine if the device's current power output exceeds the maximum power consumption requirement of the target power mode. Based on the comparison result, a correction command is generated, instructing the target device's power to be reduced from 120W to 50W and unnecessary functional modules, such as the battery charging module, to be shut down. After executing the correction command, the energy consumption switching control system successfully switches the target device to a low-power mode, ensuring that the target device reaches the predetermined target operating state, thereby optimizing energy efficiency and reducing energy consumption.

[0063] Optionally, the step of switching and / or adjusting the power consumption of the target device based on the target power consumption mode further includes: determining whether the target device needs to perform a switching operation based on the target power consumption mode; after performing a mode switching operation, if the target power consumption mode is a low power consumption mode, controlling the target device to reduce its power consumption to a first preset energy consumption value and turning off the corresponding functional components; when no switching operation is required, controlling the target device to maintain real-time operating status and output; after performing a mode switching operation, if the target power consumption mode is a power supply mode, controlling the target device to increase its power consumption to a second preset energy consumption value and turning on the corresponding functional components.

[0064] In one possible embodiment, such as Figure 5 As shown, the above method and steps can also be implemented through the following system: An energy consumption switching control system, comprising an inverter, an energy storage unit, a photovoltaic assembly, a backup load, a grid load and a detection unit, the inverter is used for receiving direct current electric energy from the photovoltaic assembly and the energy storage unit, and converting the direct current electric energy into alternating current, the inverter is provided with a Backup output end for outputting to the backup load; The energy storage unit is electrically connected with the inverter, and is used for storing surplus electric energy generated by the photovoltaic assembly, and providing electric energy when the grid is powered off or the load is required; The detection unit is signal connected with the inverter, and is used for collecting and feeding back power grid power consumption parameters, and cooperating with the inverter to perform grid-connected and off-grid operation control; The backup load is connected with the Backup output end of the inverter, and is used for continuing to supply power when the grid is powered off; The grid load is connected in parallel with the inverter and the grid, and is used for being supplied with power through the grid or the inverter in a normal power supply state.

[0065] The inverter refers to a power conversion device for converting direct current electric energy into alternating current electric energy, and usually has multiple interfaces such as photovoltaic input, battery input, grid-connected output and Backup output, and supports two working modes of grid-connected and off-grid. In the present application, the inverter also has power consumption mode control capability.

[0066] The photovoltaic assembly refers to a photovoltaic power generation unit for converting solar energy into direct current electric energy, and includes a photovoltaic panel and a support circuit thereof, and is one of main power generation sources of the system.

[0067] The energy storage unit refers to a power storage device connected with the inverter, and is usually a lithium ion battery pack, and is used for storing excess electric energy generated by the photovoltaic assembly, and supplying power when the load is required or the grid is powered off.

[0068] The backup load refers to a key power consumption device connected to the Backup port of the inverter, such as a router, lighting, a refrigerator and the like, and has important operation guarantee requirements, and is preferentially supplied with power by the energy storage unit when the grid is powered off.

[0069] The grid load refers to a power consumption device normally supplied with power through the grid or the inverter, and has a lower power consumption priority than the backup load, and is supplied with power by the mains in a grid-connected state, and can be partially supplied with power by the inverter in an off-grid state.

[0070] The detection unit refers to a smart meter or a parameter acquisition module in communication connection with the inverter, and is used for detecting voltage, current, power and the like in real time, and feeding back data to a control system, and is used as a basis for judging power consumption mode switching, and in the embodiment, the detection unit can be a smart meter supporting an RS485 communication interface, or can be other acquisition devices with the same or similar monitoring and communication functions.

[0071] Backup output is the backup output interface of the inverter, which automatically maintains the output state in the off-grid (power grid outage) case, and preferentially guarantees the continuous power supply capability of the load connected thereto.

[0072] The low-power mode refers to an energy-saving operation mode of the inverter in a small load or no load, zero photovoltaic power generation, battery standby and the like, in which unnecessary components are turned off and standby power is reduced, so as to prolong the service life of the system and improve the energy efficiency.

[0073] The energy supply mode refers to an operation mode of the inverter in an active power supply state, which can respond to the requirements of external load, power grid interruption, discharge request and the like, and provide stable alternating current output to support load work.

[0074] The grid-connected state refers to a mode in which the inverter is connected with the power grid and operates, and the system can supply power to the power grid or take power from the power grid, and participate in bidirectional power regulation.

[0075] The off-grid operation control refers to a control process in which the system switches to an off-grid power supply state when the power grid is powered off, abnormal or the user manually cuts off the power grid connection, and usually triggers the backup load power supply strategy and power consumption strategy adjustment.

[0076] Further, in the energy consumption switching control system described in the embodiment, the inverter is the core hub of energy flow and control instructions, which collects direct current from the photovoltaic module and the energy storage unit, and in the grid-connected state, the excess power is connected to the power grid, or in the off-grid state, the backup load is preferentially powered through the Backup port, to realize adaptive switching of different working modes. At the same time, the detection unit collects the power consumption parameters (such as voltage, current, active power, etc.) of the power grid in real time, and transmits the data to the control module through the communication link, to determine whether the current system is in a high-energy consumption or low-energy consumption operation state.

[0077] When the system determines that it is currently in a low-load or standby working condition, and the battery power is sufficient and the photovoltaic power output is zero, the inverter working mode can be switched to the low-power mode by the control module, for example, the PWM drive of part of the bridge arm is turned off, the output power is limited, the battery charging function is turned off, and the like, so as to effectively reduce the standby power consumption of the system and prolong the service life of the battery; when the user load increases, the power meter feedbacks the power outage or receives the external charging / discharging instruction, the control module immediately wakes up the inverter to enter the energy supply mode, quickly starts the backup power supply, and guarantees the uninterrupted operation of the load.

[0078] Through the cooperation of the above hardware structure and control logic, the energy consumption switching control system provided by the embodiment can not only meet the multi-mode power consumption management demand in a complex power supply scene, but also realize efficient switching based on electrical parameters and instruction behaviors without relying on an additional controller, improve the overall energy efficiency of the system, and reduce invalid energy consumption expenditure.

[0079] In the embodiment of the application, the first preset energy consumption value can be a maximum power consumption limit value of the target device in a low-power mode. For example, by controlling the operation of the inverter bridge (IGBT module) and other power electronic components, the power consumption of the target device is limited to a preset value. Generally, the first preset energy consumption value is low, which is used to reduce unnecessary energy consumption, such as reducing the power output of the inverter or shutting down unnecessary functions.

[0080] The second preset energy consumption value can be a power consumption target value of the target device in a power supply mode. When in the power supply mode, the target device needs to provide a higher power output to ensure that the load demand is met, which can be achieved by improving the power output through the inverter bridge (IGBT module), battery charging and discharging module, etc.

[0081] The functional components can be modules or parts in the target device that can affect power consumption. For example, battery charging module, inverter bridge, power management system, etc. These functional components can be selectively turned off or enabled according to the change of the power consumption mode, so as to realize the adjustment and optimization of power consumption.

[0082] In a possible embodiment, in the low-power mode, the power consumption can be reduced to the first preset energy consumption value by turning off the IGBT module in the inverter bridge and the battery charging and discharging module, thereby reducing unnecessary energy consumption; and in the power supply mode, the power consumption of the target device is increased to the second preset energy consumption value, and necessary functional components such as the inverter bridge and the battery charging and discharging module are enabled to meet the load demand.

[0083] By managing the power consumption through the above method steps, the energy efficiency of the target device can be improved, energy waste is reduced, and the power consumption can be flexibly adjusted according to the actual demand, thereby prolonging the service life of the device and reducing the operating cost.

[0084] Optionally, in the step of determining whether the target device needs to perform the switching operation based on the target power consumption mode, the step of determining whether the target device needs to perform the switching operation based on the target power consumption mode includes: matching the target power consumption mode with the power consumption mode in the current working state of the target device to determine whether the current power consumption mode of the target device needs to be switched; if the target power consumption mode does not match the power consumption mode in the current working state of the target device, the switching operation is performed; and if the target power consumption mode matches the power consumption mode in the current working state of the target device, the switching operation is not performed.

[0085] In this embodiment of the invention, the aforementioned energy consumption switching control system can switch power consumption modes according to external demands or preset conditions. Specifically, the energy consumption switching control system matches the target power consumption mode (such as a low-power mode or a high-power mode) with the power consumption mode of the target device in its current operating state. If the target power consumption mode does not match the current power consumption mode, the energy consumption switching control system will perform a switching operation to adjust the device's power consumption to the target mode. For example, when the device is in a high-power mode and the user requests a switch to a low-power mode, unnecessary functional modules (such as battery charging modules or inverter bridges) will be shut down as required, and the power consumption will be reduced to a preset value. If the target power consumption mode matches the current operating mode, the system will maintain the current state and will not perform a switch, thereby avoiding unnecessary operations.
