An auxiliary decision-making method for abnormal processing of power grid dispatching

Abstract

The invention discloses an auxiliary decision-making method for abnormal processing of power grid dispatch, which comprises the following steps: obtaining historical data of the power grid, predicting the load of the power grid according to the historical data, and formulating an emergency mechanism according to the forecast result; setting the forecast results of the power grid in different time periods the preference of the power grid, and give risk prompts according to the preference of the prediction result; obtain the real-time data of the power grid, and generate the load transfer and power grid restoration scheme according to the real-time data of the power grid as the reference scheme of the dispatcher; the present invention can realize the power grid load analysis, Taking pre-control measures for load equipment can realize real-time grid risk analysis and reveal risks in different time periods, which is more efficient and more comprehensive than the current manual analysis. In addition, it can also realize intelligent generation of load transfer plans, and busbar voltage loss recovery plans. Automatic generation, to a certain extent, reduce the workload of the dispatcher to prepare the plan.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to an auxiliary decision-making method for abnormal processing of power grid dispatching. Background technique [0002] With the construction and development of the power grid, the scale of the power grid has become larger and larger, the structure of the power grid has become more and more complex, and the requirements for the reliability of power supply have become 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 supply transfer plan to control the cross-section of overloaded equipment, and it is difficult to quickly have a comprehensive power restoration plan. [0003] When analyzing the status quo of abnormal handling, there are several prominent problems: [0004] First, in terms of heavy overload handling, when an accide...

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.
