[0027] Currently, existing home energy management devices have limited functionality and several shortcomings: First, energy data is limited; for example, electricity meters only provide total electricity consumption data and cannot accurately capture scattered energy data. Second, each energy management system is a separate entity and cannot be effectively interconnected to form a data chain, making it difficult to manage and schedule energy in a coordinated manner. Third, there are certain security vulnerabilities in home energy network data. Fourth, energy gateways are limited in functionality, processing capacity, and data throughput, resulting in poor real-time data processing.
[0028] To address the aforementioned technical problems, this invention provides a home energy management system. This system has an independent management module that can collect dispersed home energy data and perform unified management and scheduling of home energy based on the collected data. This improves the speed of home energy data processing and enhances the real-time performance and security of home energy management.

The energy storage converter can control the charging or discharging of the battery module and can control the charging and discharging power. Based on the energy storage converter, the battery can discharge when the power generation module's power supply is insufficient and charge when the power generation module's power supply is surplus, thereby achieving self-generation and self-consumption of household energy and reducing the interaction between the household energy system and the power grid.
[0032] In this embodiment, please refer to Figure 2 The management module includes a controller, a memory component, and an energy control component. The controller is implemented based on a Linux system (e.g., a Linux system based on an ARM9 hardware platform). The energy control component is connected to the power controller and the energy storage converter, respectively. The memory component includes two storage units, which are used to store the configuration files of the power generation module, the energy storage module, and the load module, and the two storage units serve as backups for each other.
[0033] In a further embodiment, please refer to Figure 2The management module also includes a communication module, which includes at least two wireless communication units and at least two wired communication units. The wireless communication units are one of a Wi-Fi module, a radio frequency module, a Bluetooth module, and an IoT module. The wireless communication units are used to connect to a cloud server or a mobile control terminal.
[0034] In a further embodiment, please refer to Figure 2 The management module also includes a watchdog component, a debug interface component, an interaction interface component, and a status feedback component.

The interaction interface component is connected to both the controller and an external interaction device. The interaction interface is used to transmit instructions from the external interaction device to the controller. The status feedback component is connected to the controller to issue feedback information based on the controller's status.

[0037] This invention also provides a home energy management method, which can be applied to the management module of a home energy management system according to any of the above embodiments. Please refer to... Figure 5 The methods include: Step S101: Obtain energy system data, which indicates the topology and equipment parameters of the home energy system.
[0038] Step S102: Update the configuration file of the home energy management system based on the energy system data.
[0039] In some embodiments, when a new device (power generation device, battery device, or controllable load device) is added to the home energy system, the corresponding configuration file needs to be updated to ensure that the management module can control the corresponding device, thereby achieving interconnected control.
[0040] Step S103: Obtain energy status data, which indicates the energy supply and consumption of the home energy system.
[0041] In some possible implementations, energy status data includes power generation, power consumption, and battery capacity. Based on the difference between power generation and power consumption, it can be determined whether current power generation is excessive, and based on battery capacity, it can be determined the available power allocation range for the management module.
[0042] Step S104: Determine energy management strategies based on energy status data.
[0043] In some embodiments, the energy management strategy prioritizes self-consumption, that is, it tries to match the power generation capacity of the power generation module with the power consumption capacity. When the power generation capacity and the power consumption capacity are mismatched, the excess or insufficient power is adjusted by the battery first, so as to reduce the interaction between the home energy system and the grid while complying with various power limits.
[0044] For details, please refer to Figure 6 The energy management strategy determined based on energy status data includes: when power generation is greater than power consumption and battery capacity is less than a first preset value, the energy management strategy is to charge the battery; when power generation is greater than power consumption and battery capacity is greater than or equal to the first preset value, the energy management strategy is to feed power to the grid; when power generation is less than power consumption and battery capacity is greater than a second preset value, the energy management strategy is to discharge the battery; and when power generation is less than power consumption and battery capacity is less than the second preset value, the energy management strategy is to draw power from the grid. The first preset value indicates a battery charging threshold, and the second preset value indicates a battery discharging threshold.
[0045] Step S105: If the configuration file is successfully verified, adjust and control the power of the power generation module, energy storage module and load module in the home energy management system based on the energy management strategy.
[0046] In some embodiments, the memory component of the management module includes a main storage unit and a backup storage unit. The main storage unit stores the configuration file, and the backup storage unit stores a backup file of the configuration file. Before the configuration file is successfully verified, please refer to... Figure 7The method also includes: if both the configuration file and the backup file are verified as valid, the configuration file is confirmed as successfully verified; if only the configuration file is verified as valid, the backup file is updated using the configuration file; if only the backup file is verified as valid, the configuration file is updated using the backup file; if both the configuration file and the backup file are verified as invalid, the default configuration data is obtained and the configuration file and the backup file are updated.
[0047] In some embodiments, please refer to Figure 8 The method also includes: if the configuration file verification fails, obtaining the cloud configuration file and generating a cloud energy management policy based on the cloud configuration file; if obtaining the cloud configuration file fails, obtaining the user-defined configuration file and generating a user-defined energy management policy based on the user-defined configuration file.
