Power grid dispatching exception handling auxiliary decision-making method

Abstract

The invention discloses a power grid dispatching exception handling auxiliary decision-making method, which comprises the following steps: obtaining historical data of a power grid, predicting a powergrid load according to the historical data, and formulating an emergency mechanism according to a prediction result; setting preferences of a power grid prediction result in different time periods, and performing risk prompting according to the preferences of the prediction result; and acquiring real-time data of the power grid, and generating a load transfer and power grid power restoration scheme as a reference scheme of a dispatcher according to the real-time data of the power grid. According to the power grid dispatching exception handling auxiliary decision-making method, power grid loadanalysis can be realized; precontrol measures are taken for heavy-load equipment; real-time power grid risk analysis can be achieved; risks in different time periods are revealed; the power grid dispatching exception handling auxiliary decision-making method is more efficient and comprehensive than existing manual analysis; and in addition, intelligent generation of a load transfer scheme and automatic generation of a bus no-voltage power restoration scheme can be achieved, and the workload of plan writing of a dispatcher is reduced to a certain degree.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to an auxiliary decision-making method for abnormal handling of power grid dispatching. Background technique [0002] With the construction and development of the power grid, the scale of the power grid is getting larger and larger, the structure of the power grid is becoming more and more complex, and the requirements for power supply reliability are getting higher and higher. The pressure is also increasing. In the face of complex large-scale power outages, there will be an extreme shortage of manpower. It is difficult to quickly have a comprehensive power transfer plan to control the section of overloaded equipment, and it is difficult to quickly have a comprehensive power restoration plan. [0003] Analyzing the status quo of exception handling, there are several prominent issues: [0004] First, in terms of heavy overload handling, when an accident occurs in the power grid...

AI Technical Summary

Problems solved by technology

[0004] First, in terms of heavy overload handling, when an accident occurs in the power grid, the equipment may be heavily overloaded, and if the equipment is overloaded, if the control is not effective, it may cause secondary accidents. Electricity takes a long time

[0005] Second, in terms of power recovery of voltage-loss equipment, when a large number of busbars lose voltage, the controller lacks a systematic and rapid power recovery plan

[0006] The third is risk identification. In the process of abnormal handling, controllers mainly focus on abnormal handling and accident handling, and lack a fast and reliable judgment on the risk after the accident.
