Description

Technical Field

[0001] The present invention relates to the technical field of smart meters, and in particular to a power dispatching system and method based on smart meters. Background Art

[0002] As global energy consumption continues to grow, the problem of grid load fluctuations has become increasingly prominent, especially during peak electricity consumption periods. The phenomenon of concentrated electricity consumption by users will cause a sharp increase in the grid's carrying pressure and may even cause problems such as grid overload and equipment failure. At the same time, during low electricity consumption periods, due to the decrease in electricity demand, the excess electricity in the grid cannot be effectively consumed, resulting in energy waste.

[0003] For example, patent CN118763732A discloses an intelligent control optimization method and system for a power grid system. Although it can collect power grid data through sensors and smart meters, conduct real-time analysis and adjust control strategies, and automatically optimize power distribution, it is still unable to comprehensively adjust the power of household electricity according to the load status of the power grid and the needs of users.

[0004] Therefore, it is necessary to develop an electric power dispatching system that can intelligently adjust household electricity power according to the load status of the power grid and household electricity demand. Summary of the invention

[0005] In view of this, the present invention aims to propose a power dispatching system and method based on smart meters to solve the problem in the prior art that it is impossible to intelligently adjust household electricity power according to the grid load conditions and household electricity demand to achieve grid load balancing.

[0006] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0007] A household power dispatching method based on a smart meter comprises the following steps:

[0008] S1: Receive grid load information fed back by the power company and enter S2;

[0009] S2: According to the load information of the power grid, determine the load status of the power grid. If the power grid is in a high load state, enter S3; if the power grid is in a low load state, enter S4; if the load status of the power grid is normal, enter S5;

[0010] S3: Execute the first control mode to reduce the power of household electricity and enter S1;

[0011] S4: Execute the second control mode to increase the power of household electricity and enter S1;

[0012] S5: Execute the third control mode, automatically adjust the power of household electricity, and enter S1.

[0013] This application can flexibly adjust the power of household electricity according to the load information of the power grid, avoid excessive electricity consumption under high load conditions, reduce the burden on the power grid, and increase electricity consumption under low load conditions, maximize the utilization of power resources, and achieve power grid load balance.

[0014] Furthermore, the first control mode in step S3 includes:

[0015] S31: Detect and determine whether there are controlled electrical appliances in operation at home, if so, enter S32, if not, enter S1;

[0016] S32: Detect and determine whether there is anyone at home, if yes, go to S33, if not, go to S35;

[0017] S33: Sending a prompt message to remind the user to reduce the power of household electricity, and then entering S34;

[0018] S34: Determine whether the power of household electricity has decreased, if so, go to S1, if not, go to S33;

[0019] S35: Stop supplying power to the controlled electrical appliances and enter S1.

[0020] When there is someone at home, a prompt message will be sent to remind the user. Through user participation, the power of household electricity can be reduced and the load on the power grid can be reduced, and the needs of users can be met. When no one is at home, the power supply to the controlled appliances can be stopped, which can save energy and reduce the load on the power grid, as well as reduce the risk of appliance failure, reduce potential fire hazards, and enhance the safety of household electricity use.

[0021] Furthermore, the second control mode in step S4 includes:

[0022] S41: Detect and determine whether there is anyone at home, if yes, go to S42, if not, go to S1;

[0023] S42: Send a prompt message to remind the user to increase the power of household electricity consumption, and enter S1.

[0024] This setting can not only absorb excess electricity from the power grid, but also help users develop good electricity usage habits and save electricity costs.

[0025] Furthermore, the third control mode in step S5 includes:
