Hierarchical scheduling method for power distribution network users

Abstract

The invention discloses a hierarchical scheduling method for power distribution network users. The hierarchical scheduling method comprises the steps of building a hierarchical scheduling model and acquiring parameters; calculating priorities of all users, sorting and selecting a plurality of users for hierarchical scheduling; calculating a forgetting factor and updating communication parameters of all users; and repeating the steps to continuously perform hierarchical scheduling of the power distribution network users. According to the method, power distribution network side services are partitioned, advanced users and common users are defined, and when a base station allocates wireless resources, it is guaranteed that users in a production control class can be scheduled earlier; then, a forgetting factor function is provided by combining the variance of the priority of the high-level users, so that forgetting factors are dynamically changed according to the scheduling condition of the high-level users, the scheduling time of the high-level users is shortened, and fair scheduling of the users in a short period is ensured; therefore, the method can ensure safe and stable operation of the power grid, gives consideration to both long-term fairness and short-term fairness, and is high in reliability and good in practicability.

Description

technical field [0001] The invention belongs to the field of electric automation, and in particular relates to a hierarchical scheduling method for power distribution network users. Background technique [0002] With the development of economy and technology and the improvement of people's living standards, electric energy has become an indispensable secondary energy source in people's production and life, bringing endless convenience to people's production and life. Therefore, ensuring the stable and reliable operation of the power system has become one of the most important tasks of the power system. With the increasing popularity of commercial 5G networks, the integration of power systems and 5G networks is also accelerating. [0003] The dispatching of power distribution network users has always been an important research content of power system. The distribution network business of the smart grid is basically divided into four categories: production control type I are...

AI Technical Summary

Problems solved by technology

[0004] Traditional distribution network user scheduling uses a proportional fairness algorithm: this algorithm obtains long-term user scheduling fairness by sacrificing system speed; Fairness of users; moreover, users in higher security partitions run the risk of having difficulty transferring data in the short term

Therefore, the existing traditional distribution network user scheduling method has certain defects
