Description

Technical Field

[0001] The present invention discloses a method and system for interactively regulating electric load and power grid based on big data technology, and relates to the field of electric load regulation. Background Art

[0002] The existing interactive regulation process between power load and power grid has the following deficiencies:

[0003] Insufficient fault tolerance: The current power load control system has certain deficiencies in fault tolerance, which can easily cause system operation interruption or data loss. Especially in complex power systems, equipment failures or human errors often occur, resulting in weak data processing capabilities of existing power load control systems.

[0004] Technical complexity and maintenance cost: The interactive control system of electric power loads integrates data processing technologies such as power control, transmission control, and data mining. This makes the system's technical complexity high and requires the design of a variety of different mathematical models or calculation formulas, which places high demands on the technical level of maintenance personnel.

[0005] Narrow scope of application: The existing power load control system mostly operates only for a specific area or a single-phase power supply line. This processing method can control power for a specific area when the power of the upper power grid is sufficient. Once the power of the upper power grid is insufficient or a new power grid is built in the area, it will cause the original failure. Especially in complex power systems, this situation often occurs.

[0226] Ee (2) =ei (2) ×(re (2) × (2) ) 1 / 2 +ae (2) ;

[0227] Step S15: Similarly, calculate the expected power consumption of the mnth city district, denoted as Ee (mn) ;
