Description

Technical Field

[0001] The present application relates to the technical field of power grid balancing, and in particular to a power grid load balancing control system and method based on load integration. Background Art

[0002] In today's power supply sector, the stable operation of the power grid is crucial, and load balancing and control are the key to ensuring this stability. As the scale of electricity consumption continues to expand and the devices using it become increasingly diverse, the load situation on the power grid is becoming increasingly complex and changeable.

[0003] The inventors discovered during their research on the prior art that the following problems exist when performing load balancing control on the power grid:

[0004] 1. Most control methods lack comprehensive consideration of load characteristics and grid balance characteristics. They often simply treat the loads uniformly, making it difficult to accurately adapt to the timing differences in power consumption of different loads, resulting in poor control effects.

[0005] 2. The ability to respond to dynamic changes in load conditions is insufficient. It is impossible to flexibly adjust the control strategy according to load changes in real time, update the relevant elements of load integration in a timely manner, and determine the appropriate time to enter the power grid for control. This makes the power grid prone to imbalance when facing complex load changes, affecting the power supply quality and the overall stability of the power grid.

[0006] Chinese patent number CN202411427773.8 discloses a load balancing control method and system for an energy storage device. However, the invention's research on energy storage devices has poor applicability in the context of increasingly complex and changeable grid load conditions. Furthermore, the invention relies on specific Gaussian processing methods, modal decomposition methods, and hybrid neural networks for control. The method is relatively simple and lacks coordination and cooperation to flexibly respond to load changes, making it poorly adaptable to balancing control under complex working conditions.

[0007] In summary, there is an urgent need for a new technical solution for load balancing and control of power grids based on load integration, which can effectively combine load characteristics with grid balancing requirements and have dynamic adjustment capabilities to improve the stability of grid operation and power supply quality.
