These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this invention 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 embodiments of the invention described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0044] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0045] In today's society, with the rapid development of science and technology and the continuous growth of the population, global energy demand continues to rise, while environmental problems such as pollution and climate change are becoming increasingly severe. As a major unit of energy consumption, the energy efficiency of households and the implementation of energy conservation and emission reduction measures directly affect the improvement of global energy structure and environmental quality.

[0046] Currently, various household energy systems exist, such as solar water heating systems and wind power systems, which to some extent utilize renewable energy and demonstrate the promising future of green energy. However, most existing energy-saving systems are still relatively traditional in design, lacking intelligent and integrated management methods. They operate independently, lacking effective linkage with other energy systems and household appliances, resulting in low energy efficiency.

[0047] To address the aforementioned issues, the energy-saving system control method provided in this application collects and analyzes in real time the output power of the energy-saving system (including the direct output of the renewable energy harvesting device and the total power provided jointly by the energy storage device in discharge mode) and the real-time energy consumption data of each electrical device. Based on this dynamic information, the method intelligently decides and controls the power supply strategy, flexibly selecting from various modes such as independent power supply from the renewable energy harvesting device, supplementary power supply from the mains, or complete reliance on mains power supply, to ensure that electrical devices receive stable and efficient energy support. This method not only achieves the effective integration and synergistic utilization of multiple renewable energy sources, but also optimizes energy allocation and use through refined control strategies, thereby significantly improving energy utilization efficiency and enhancing the system's energy-saving effect while meeting the energy needs of the electrical space.

[0048] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0049] Figure 1 This is the flow chart of the control method for the energy-saving system provided in this application. Figure 1 The implementing entity in this embodiment is, for example, an energy-saving power supply control system. Figure 1 As shown, the control method for the energy-saving system provided in this embodiment includes:

[0050] S101: Obtain the output power of the energy-saving system and the real-time power of the electrical equipment, wherein the output power of the energy-saving system is the output power of the renewable energy acquisition device, or the sum of the output power of the renewable energy acquisition device and the output power of the energy storage device under discharge conditions.

[0051] The energy-saving system includes one or more renewable energy collection devices and energy storage devices.

[0052] Renewable energy harvesting devices can be solar photovoltaic panels, wind turbines, and hydroelectric generators. These devices are used to convert renewable natural resources (such as solar, wind, and hydropower) into electrical energy.

[0053] Energy storage devices can be battery packs or supercapacitors. They store electrical energy generated by renewable energy harvesting devices and release it for use when needed. High-performance energy storage devices offer excellent charging and discharging efficiency and a long lifespan, ensuring a stable power supply for the entire house even when energy supply is unstable.

[0054] First, sensors are installed at the output end of the renewable energy collection device to monitor its output power in real time. Second, smart sockets or electricity meters are configured for each electrical device to detect its power consumption in real time. Finally, the data acquisition unit transmits the data collected by the sensors and detection units to the energy-saving control system for processing and analysis. High-precision, real-time energy detection can accurately obtain the output and storage status of various energy sources, as well as the energy consumption of electrical devices, providing reliable data support for intelligent control.

[0055] The output power of the energy-saving system can be the output power of the renewable energy collection device, or it can be the sum of the output power of the renewable energy collection device and the output power of the energy storage device under discharge conditions.

[0056] The output power of a renewable energy harvesting device refers to the electrical energy that the renewable energy conversion equipment (such as solar photovoltaic panels, wind turbines, and hydroelectric generators) installed in an energy-saving system can convert and output based on environmental conditions (such as sunlight intensity and wind speed). This power is the main and direct energy source of the energy-saving system, and it directly reflects the utilization efficiency of renewable energy and the power generation capacity of the energy-saving system.

[0057] When the electricity generated by renewable energy harvesting devices exceeds immediate demand or when power generation capacity decreases due to environmental factors (such as nighttime or windless weather), energy storage devices (such as battery packs or supercapacitors) store the excess energy. When needed (such as during periods of insufficient sunlight or peak electricity consumption), the energy storage devices release the stored energy to supplement the insufficient output of the renewable energy harvesting devices. Therefore, the output power provided by the energy storage devices during discharge is also part of the energy-saving system's output function.

[0058] S102: Based on the output power of the energy-saving system and the real-time power of the electrical equipment, control the use of renewable energy collection devices and / or mains power to supply power to the electrical equipment.

[0059] Among them, renewable energy collection devices can convert different forms of energy output into unified DC or AC power to adapt to electrical equipment.

[0060] Power supply control based on the output power of the energy-saving system and the real-time power of the electrical equipment means that the energy-saving control system will intelligently select to use renewable energy, mains power, or a combination of both to power the electrical equipment, based on the current output capacity of the renewable energy harvesting device, the reserve status of the energy storage device, and the real-time power demand of each electrical device. The energy-saving power supply control strategy aims to maximize the utilization of renewable energy while ensuring the stable operation of electrical equipment and the efficient use of energy.

[0061] Understandably, the process involves several steps. First, real-time acquisition of the energy-saving system's output power, the energy storage status of the energy storage device, and the real-time power demands of each electrical device is crucial. Second, based on the energy-saving power supply control strategy and the detected data, a power supply plan is determined. This strategy includes determining when to use renewable energy and when to switch to grid power. Then, the power distribution is adjusted in real-time through the energy-saving power supply control system to ensure a stable and reliable power supply for the electrical devices. Finally, the energy-saving power supply control system is regularly maintained and optimized to ensure the accuracy of the detection data and the effectiveness of the energy-saving power supply control strategy, adapting to constantly changing energy demands and environmental conditions.

[0062] Optionally, if the energy-saving system includes multiple renewable energy harvesting devices, the control of using renewable energy harvesting devices to power electrical equipment includes:

[0063] According to the preset priority order of multiple renewable energy collection devices from high to low, control the use of some or all of the multiple renewable energy collection devices to supply power to the electrical equipment.

[0064] Prioritizing the use of electricity generated by renewable energy harvesting devices can reduce dependence on grid power and lower carbon emissions. Secondly, adjusting power supply based on the real-time power demands of electrical equipment can prevent energy waste and overload, ensuring the stable operation of the energy-saving control system. Furthermore, energy-saving power supply control strategies help balance the intermittency of renewable energy sources with the volatility of electricity demand, improving the reliability and stability of energy supply.

[0065] Optionally, when there are multiple electrical devices, the method further includes:

[0066] Based on the preset priorities of multiple electrical devices, control a preset number of electrical devices with lower priority to shut down or reduce power.

[0067] To improve energy efficiency and ensure the stable operation of critical electrical equipment, the energy-saving power supply control system intelligently adjusts power consumption based on pre-set priorities for each device. Specifically, it first identifies and prioritizes all electrical equipment. Then, based on the current power load or preset energy-saving strategies, it automatically selects a preset number of lower-priority devices and shuts them down or reduces their operating power. This effectively reduces energy consumption from unnecessary or low-priority devices while prioritizing the normal operation of high-priority devices, thus achieving energy conservation and emission reduction while ensuring the stability and efficiency of the overall power supply.

[0068] This embodiment also allows users to remotely control the energy-saving power supply system by designing an intuitive and easy-to-use user interface and combining it with powerful remote control functions. The energy-saving power supply system has a built-in wireless communication module, such as Wi-Fi and Bluetooth technology, which connects to users' mobile phones, tablets, and other smart terminals, making it convenient for users to control the energy-saving power supply system. At the same time, to be compatible with a wider range of home network environments, the energy-saving power supply system is also equipped with a wired communication module, such as an Ethernet interface, ensuring connectivity with home smart gateways and other smart home devices, enabling rapid data exchange and sharing, further enhancing the intelligence and convenience of home life.

[0069] The energy-saving system control method provided in this embodiment obtains the output power of the energy-saving system and the real-time power of the electrical equipment. The output power of the energy-saving system is the output power of the renewable energy collection device, or the sum of the output power of the renewable energy collection device and the output power of the energy storage device under discharge conditions. Based on the output power of the energy-saving system and the real-time power of the electrical equipment, the method controls the use of the renewable energy collection device and / or mains power to supply power to the electrical equipment. This method can integrate multiple renewable energy sources and achieve efficient satisfaction and utilization of the energy demand of the electrical space through intelligent energy-saving power supply control strategies, significantly improving the energy-saving effect.

[0070] Figure 2 This is the flow chart of the control method for the energy-saving system provided in this application. Figure 2 .like Figure 2 As shown, in this embodiment... Figure 1 Based on the embodiments, the control method of the energy-saving system is described in detail. The control method of the energy-saving system shown in this embodiment includes:

[0071] S201: Obtain the output power of the energy-saving system and the real-time power of the electrical equipment, wherein the output power of the energy-saving system is the output power of the renewable energy acquisition device, or the sum of the output power of the renewable energy acquisition device and the output power of the energy storage device under discharge conditions.

[0072] The renewable energy harvesting device includes solar energy harvesting modules, wind energy harvesting modules, and hydropower harvesting modules. Solar energy harvesting modules include solar panels, inverters, etc., used to convert solar energy into electrical energy; wind energy harvesting modules include small wind turbines, rectifiers, etc., used to convert wind energy into electrical energy; hydropower harvesting modules can be, for example, micro-hydropower generators and related conversion equipment.

[0073] Energy storage devices include battery packs and battery management systems. Battery packs, such as lithium-ion battery packs, are used to store excess harvested energy. The battery management system monitors battery status, including charge, voltage, and temperature, ensuring safe and efficient battery operation.

[0074] S202: If the output power of the energy-saving system is greater than or equal to the real-time power of the electrical equipment, and the power of the energy storage device is less than the charging threshold, then the system controls the use of renewable energy collection devices to supply power to the electrical equipment and to charge the energy storage device.

[0075] Understandably, firstly, the energy-saving power supply control system needs to monitor the output power of the energy-saving system, the real-time power of the electrical equipment, and the energy storage device's charge status in real time. Secondly, when the energy-saving power supply control system detects that the output power of the energy-saving system is greater than or equal to the real-time power of the electrical equipment, and the energy storage device's charge is less than the charging threshold, it will automatically trigger the energy-saving power supply control mechanism. Then, the energy-saving power supply control mechanism will adjust power distribution, prioritizing the use of renewable energy harvesting devices to supply power to the electrical equipment, and calculating the amount of electricity needed to charge the energy storage device through intelligent control algorithms. Finally, the energy-saving power supply control system will execute these control commands to ensure the stable operation of the electrical equipment and the effective charging of the energy storage device. Throughout the entire process, the energy-saving power supply control system also needs to continuously monitor and adjust to ensure optimal and real-time energy management.

[0076] When the output power of the energy-saving system is sufficient to meet the real-time power demand of all electrical devices, if the energy storage device's power level falls below a preset charging threshold, the energy-saving power supply control system will automatically adjust, prioritizing the use of renewable energy harvesting devices to power the electrical devices, while simultaneously utilizing excess power to charge the energy storage device. This energy-saving power supply control strategy ensures efficient energy utilization and storage, meeting immediate power demands while preparing for potential future power shortages.

[0077] Energy-saving power supply control strategies maximize the use of renewable energy, reduce reliance on traditional energy sources, and help lower operating costs and reduce environmental pollution. Secondly, by charging energy storage devices, the energy-saving power supply control system can provide additional power support when renewable energy is insufficient or when electricity demand surges, enhancing the reliability and stability of energy supply. Furthermore, intelligent power supply control methods improve energy utilization efficiency, avoid electricity waste, and achieve optimal energy allocation.

[0078] S203: If the output power of the energy-saving system is greater than or equal to the real-time power of the electrical equipment, and the energy storage device has a charge greater than or equal to the charging threshold, then the control will use the renewable energy collection device to supply power to the electrical equipment.

[0079] When the output power of the energy-saving system is sufficient to meet the real-time power needs of all electrical devices, and the energy storage device's charge level is maintained at or above the preset charging threshold, the energy-saving power supply control system will intelligently select to use only the renewable energy harvesting device to supply power to the electrical devices. This energy-saving power supply control strategy aims to maximize the utilization of renewable energy while avoiding unnecessary charging of already fully charged energy storage devices, thereby saving energy and extending the lifespan of the energy storage devices.

[0080] Adopting energy-saving power supply control strategies can effectively improve energy utilization efficiency and the economics of energy-saving system operation. Firstly, by directly utilizing renewable energy to power electrical equipment, reliance on energy storage devices can be reduced, thus avoiding unnecessary charge-discharge cycles when the storage devices are fully charged, reducing energy loss and wear and tear on the storage devices. Secondly, energy-saving power supply control strategies contribute to the green and low-carbon use of energy, reducing the consumption of traditional energy sources and environmental pollution. Furthermore, it helps balance the intermittency of renewable energy and the volatility of electricity demand, ensuring the stability and reliability of power supply.

[0081] S204: If the output power of the energy-saving system is less than the real-time power of the electrical equipment, and the energy storage device has a charge greater than the discharge threshold, then the control adopts the renewable energy collection device and the energy storage device to jointly supply power to the electrical equipment.

[0082] When the energy-saving system is unable to meet the real-time power demand of the electrical equipment on its own due to certain reasons (such as insufficient renewable energy or conversion efficiency limitations), and at the same time the amount of electricity stored in the energy storage device exceeds the preset discharge threshold, the energy-saving power supply control system will automatically adjust the energy-saving power supply control strategy and start the mode of joint power supply of the renewable energy collection device and the energy storage device to ensure that the electrical equipment can continuously and stably obtain the required power.

[0083] With renewable energy sources (such as solar, wind, and hydropower) as the primary energy source, their supply is often constrained by natural conditions such as weather, resulting in instability. Meanwhile, the power demands of electrical equipment change in real time. Therefore, when energy-saving systems cannot meet immediate demand, utilizing energy storage devices as a buffer, combined with renewable energy harvesting devices to continue collecting energy, can effectively alleviate the supply-demand imbalance, prevent equipment from interrupting operation due to insufficient power supply, and improve the reliability and flexibility of the entire energy-saving system.

[0084] When the output power of the energy-saving system is detected to be less than the real-time power of the electrical equipment, and the energy storage device's charge exceeds the discharge threshold, the energy-saving power supply control system will automatically trigger corresponding instructions to adjust the energy-saving power supply control strategy. Specifically, it will activate the discharge function of the energy storage module while maintaining the normal operation of the renewable energy harvesting device, using a reasonable power distribution mechanism to jointly provide the necessary power to the electrical equipment. Furthermore, the energy-saving power supply control system must continuously monitor the operating status of each component to ensure the safety, efficiency, and stability of the power supply process.

[0085] S205: If the output power of the energy-saving system is less than the real-time power of the electrical equipment, and the energy storage device's charge is less than or equal to the discharge threshold, then the control will use the renewable energy collection device and mains power to supply power to the electrical equipment.

[0086] When the output power of the energy-saving system is insufficient to meet the real-time power demand of the electrical equipment, and the remaining power of the energy storage device has dropped to or below the preset discharge threshold, the energy-saving power supply control system will automatically adjust the energy-saving power supply control strategy, selecting to simultaneously utilize the renewable energy harvesting device and the mains power grid to supply power to the electrical equipment. This ensures that even in situations where renewable energy supply is insufficient and the energy storage device is running low on power, the electrical equipment can still obtain stable and reliable power support.

[0087] Adopting energy-saving power supply control strategies can ensure the continuous and stable operation of electrical equipment and meet its power needs. In situations where renewable energy supply is unstable or energy storage devices have insufficient power, relying solely on renewable energy harvesting devices for power may lead to power outages, affecting the normal operation of electrical equipment. The municipal power grid, as a stable and reliable power source, can provide necessary supplementation at critical moments, ensuring continuous power supply to electrical equipment. Furthermore, energy-saving power supply control strategies also help reduce excessive discharge of energy storage devices, extend their lifespan, and optimize the overall operating efficiency of the energy system.

[0088] First, the energy-saving power supply control system needs to acquire real-time information such as the output power of the energy-saving system, the real-time power demand of electrical equipment, the remaining power of the energy storage device, and the operating status of the renewable energy harvesting device. Then, based on preset logical judgment conditions (i.e., output power is less than real-time power and the energy storage device's power is less than or equal to the discharge threshold), the energy-saving power supply control system automatically triggers a power supply mode switching command. Next, the energy-saving power supply control system adjusts the power supply ratio between the renewable energy harvesting device and the mains power grid through power distribution and control mechanisms, ensuring that both can work together to provide stable power support for electrical equipment. Finally, the energy-saving power supply control system also needs to continuously monitor changes in various parameters during the power supply process and make necessary adjustments and optimizations based on actual conditions to ensure the effectiveness and reliability of energy management.

[0089] The energy-saving system control method provided in this embodiment obtains the output power of the energy-saving system and the real-time power of the electrical equipment. The output power of the energy-saving system is either the output power of the renewable energy harvesting device or the sum of the output power of the renewable energy harvesting device and the output power of the energy storage device during discharge. If the output power of the energy-saving system is greater than or equal to the real-time power of the electrical equipment, and the energy storage device's charge is less than a charging threshold, then the system controls the renewable energy harvesting device to supply power to the electrical equipment and to charge the energy storage device. If the output power of the energy-saving system is greater than or equal to the real-time power of the electrical equipment, and the energy storage device's charge is greater than or equal to a charging threshold, then the system controls the renewable energy harvesting device to supply power to the electrical equipment. If the output power of the energy-saving system is less than the real-time power of the electrical equipment, and the energy storage device's charge is greater than a discharge threshold, then the system controls the renewable energy harvesting device and the energy storage device to jointly supply power to the electrical equipment. If the output power of the energy-saving system is less than the real-time power of the electrical equipment, and the energy storage device's charge is less than or equal to a discharge threshold, then the system controls the renewable energy harvesting device and mains power to supply power to the electrical equipment. This method integrates multiple renewable energy sources and, through an intelligent energy-saving power supply control strategy, achieves efficient satisfaction and utilization of the energy demand of the electrical space, significantly improving energy-saving effects.

[0091] The acquisition module 301 is used to acquire the output power of the energy-saving system and the real-time power of the electrical equipment, wherein the output power of the energy-saving system is the output power of the renewable energy acquisition device, or the sum of the output power of the renewable energy acquisition device and the output power of the energy storage device under discharge conditions;

[0092] The control module 302 is used to control the use of renewable energy collection devices and / or mains power to supply power to the electrical equipment based on the output power of the energy-saving system and the real-time power of the electrical equipment.
