Multi-agent based distribution network disaster responding recovery coordinate control method and multi-agent based distribution network disaster responding recovery coordinate control device

Abstract

The invention provides a multi-agent based distribution network disaster responding recovery coordinate control method and a multi-agent based distribution network disaster responding recovery coordinate control device. The method comprises the steps of firstly determining an objective function and constraint conditions of distribution network disaster responding recovery, dividing a distribution network recovery stage into a backbone channel recovery stage, a local distribution network recovery stage and a region networking recovery stage, then setting the stages of distribution network recovery to be a backbone recovery Agent, a local distribution network recovery Agent and a region networking recovery Agent respectively, establishing a blackboard model based MAS coordination mechanism, establishing an MAS based distribution network recovery control decision making system, acquiring a recovery result, carrying out verification on the recovery result by adopting a verification Agent, acquiring a final recovery result, transmitting the final recovery result to a user interface Agent through a global recovery Agent, and putting an end to distribution network disaster responding recovery. Therefore, the reliability in power supply of an electric power system is improved, the power supply reliability of the electric power system under natural disaster conditions in particular is improved, and the investment income of a power grid is improved.

Description

Technical field: [0001] The invention relates to the field of transmission and distribution networks, in particular to a multi-agent-based distribution network disaster recovery coordination control method and device. Background technique: [0002] Distribution network is prone to multiple faults when natural disasters occur. For system operators, the recovery problem after a fault is a real-time multi-stage decision-making problem with different optimization objectives. At present, the existing technology divides the power system restoration process into three stages according to the main restoration objects, namely the black start stage, the grid reconstruction stage, and the full load restoration stage. However, in the research on power supply restoration of distribution network, only the stages of distribution network reconfiguration and load restoration are involved. Considering the characteristics of distribution network restoration comprehensively, the distribution n...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, when applying the Multi-Agent System (MAS) theory to solve the power supply restoration problem of the distribution network, agents are often set for different electrical components, such as feeder agents, bus agents, etc. to construct multi-agent Although the intelligent body system has a certain pertinence in dealing with the recovery problem, when faced with the power supply recovery problem of a large power distribution network, due to the huge number of electrical components itself, it leads to the "curse of dimensionality" to some extent. On the one hand, due to the lack of a good collaboration method, each agent is faced with the coordination synchronization problem, resulting in a slow recovery process, which cannot take advantage of the parallel computing of the multi-intelligence system
