Description

Technical Field

[0001] The present invention relates to power system operation management technology, and in particular to a distribution network operation management method integrating large model optimization. Background Art

[0002] With the increasing complexity of power systems and the increasing demand for renewable energy, traditional power system decision-making methods can no longer fully meet the needs of modern power systems. Modern power systems not only need to consider traditional power generation and transmission, but also need to integrate distributed energy resources (DER), such as solar power generation, wind power generation, and electric vehicle (EV) charging and discharging management. The introduction of these distributed energy resources increases the complexity and uncertainty of the power system, so a more intelligent and flexible decision support system is needed to achieve optimal management of the power system.

[0003] In order to meet this challenge, the application of large language models (LLM) in power systems has emerged in recent years. LLM is able to process large amounts of natural language data and generate corresponding mathematical models and codes for decision support in power systems. However, current LLMs still have limitations in dealing with complex power system optimization problems and perform poorly in generating complex power flow models and advanced optimization models such as second-order cone relaxation. This results in the low feasibility of relying solely on LLMs for power system optimization decisions.

[0004] At present, the main technical problems facing the power system include the following aspects:

[0005] 1. Complexity and uncertainty: The complexity and uncertainty of the power system have greatly increased, especially when integrating a large number of distributed energy resources. These resources are volatile and intermittent, which increases the complexity of system operation.

[0006] 2. Limitations of traditional methods: Traditional power system optimization methods mainly rely on the knowledge and experience of human experts, which is time-consuming and difficult to cope with dynamically changing system requirements. In addition, traditional methods have obvious deficiencies in processing large-scale data and real-time decision-making.

[0007] 3. Limitations of LLM: Although LLM performs well in natural language processing, it still has obvious limitations in the generation of power system optimization models. For example, LLM has difficulty in generating complex power flow models containing second-order cone relaxation, which limits its application in advanced decision support for power systems.

[0008] 4. Model fusion and decision support: How to effectively integrate the knowledge of human experts and the computing power of LLM to form an efficient and intelligent decision support system is a technical problem that needs to be solved urgently. The system not only needs to have real-time response capabilities, but also needs to be able to handle complex optimization problems to improve the operating efficiency and reliability of the power system.
