Interactive system between smart home and urban power grid and method thereof

Abstract

A smart home and urban power grid interaction system and method are disclosed. The smart home host receives the grid load status provided by the urban power grid server and compares the reserve margin rate and reserve capacity in the grid load status with preset percentages and preset thresholds, respectively, to determine whether the grid load status is in a power supply warning state or a power rationing warning state. Based on this, corresponding control commands are generated and transmitted to the home appliances to automatically adjust the operating status of the home appliances, thereby achieving the technical effects of improving energy utilization efficiency and grid operation stability.

Claims

1. A smart home and urban power grid interaction system, the system comprising: an urban power grid server for detecting and providing a power grid load status, the power grid load status including a reserve capacity and a reserve capacity rate; at least one home appliance having an operating state, the operating state allowing switching between a standard mode, an energy-saving mode and a shutdown mode; and a smart home host connected to the urban power grid server and the at least one home appliance, the smart home host comprising: a transmission module for receiving the power grid load status from the urban power grid server and transmitting a first control command, a second control command and a third control command to the at least one home appliance; a non-transitory computer-readable storage medium for storing a preset percentage, a preset threshold and a plurality of computer-executable instructions; and a hardware processor connected to the transmission module and the non-transitory computer-readable storage medium, the hardware processor executing the computer-executable instructions for: When the reserve margin is lower than the preset percentage, the received grid load state is determined to be a power supply warning state, and the first control command is generated to switch the operating state of the at least one household appliance to the energy-saving mode; when the reserve margin is lower than the preset threshold, the received grid load state is determined to be a power-limiting warning state, and the second control command is generated to switch the operating state of the at least one household appliance to the shutdown mode; and when the grid load state is neither the power supply warning state nor the power-limiting warning state, the third control command is generated to switch the operating state of the at least one household appliance to the standard mode.

2. The smart home and urban power grid interaction system as described in claim 1, wherein the urban power grid server generates a scheduling instruction based on the backup capacity and the backup capacity rate, and transmits the scheduling instruction to the smart home host for the user to confirm whether to execute. When the user confirms the execution of the scheduling instruction, the hardware processor prioritizes switching the operating state of the at least one home appliance according to the scheduling instruction.

3. The smart home and city power grid interaction system as described in claim 2, wherein the hardware processor calculates the number of times the scheduling instruction is executed and synchronously stores the data to the city power grid server and the non-transitory computer-readable storage medium, for use by the power company as a basis for electricity bill discounts and mutual auditing.

4. The smart home and urban power grid interaction system of claim 1, wherein the non-transitory computer-readable storage medium stores a priority order list, the priority order list defining the priority order of the at least one appliance, for selecting the at least one appliance whose operating state is to be switched according to the priority order list before switching the operating state of the at least one appliance.

5. The smart home and urban power grid interaction system as described in claim 4, wherein the priority order table sets the priority order based on the energy consumption of the at least one home appliance, and the energy consumption is positively correlated with the priority order.

6. A method for interaction between a smart home and a city power grid, applied in an environment having a city power grid server, at least one home appliance, and a smart home host, comprising the following steps: The city power grid server detects a power grid load status and provides it to the smart home host. The power grid load status includes a reserve capacity and a reserve capacity rate. When the reserve capacity rate is lower than a preset percentage, the smart home host determines that the received power grid load status is a power supply alarm status, generates a first control command, and transmits it to the at least one home appliance, causing one of the at least one home appliance to switch its operating state to an energy-saving mode. When the reserve capacity is lower than a preset threshold, the smart home host determines that the received power grid load status is a power-limiting alarm status, generates a second control command, and transmits it to the at least one home appliance, causing the at least one home appliance to switch its operating state to a shutdown mode. When the power grid load status is neither the power supply alarm status nor the power-limiting alarm status, the smart home host generates a third control command and transmits it to the at least one home appliance, causing the at least one home appliance to switch its operating state to a standard mode.

7. The method for interaction between a smart home and a city power grid as described in claim 6, wherein the method further includes the city power grid server generating a scheduling instruction based on the backup capacity and the backup capacity rate, and transmitting the scheduling instruction to the smart home host for the user to confirm whether to execute, and when the user confirms to execute the scheduling instruction, the smart home host preferentially switches the operating state of the at least one home appliance according to the scheduling instruction.

8. The method for interaction between a smart home and a city power grid as described in claim 7, wherein the method further includes the step of the smart home host calculating and storing the number of times the scheduling command is executed, and synchronously storing it to the city power grid server for use by the power company as a basis for electricity bill discounts and mutual auditing.

9. The method for interaction between a smart home and a city power grid as claimed in claim 6, wherein the method further includes the smart home host storing a priority order table, the priority order table defining the priority order of the at least one appliance, for selecting the at least one appliance whose operating state is to be switched according to the priority order table before switching the operating state of the at least one appliance.

10. The method for interaction between a smart home and a city power grid as described in claim 9, wherein the priority order table sets the priority order based on the energy consumption of the at least one home appliance, and the energy consumption is positively correlated with the priority order.
