AI Technical Summary

Technical Problem

The existing load adjustment decision-making methods rely on historical data and fixed thresholds, making it difficult to adapt to the dynamic changes of the power system, resulting in untimely or excessive load adjustments, affecting system stability and economics.

Method used

Based on the head water level prediction, the water level change mode is determined by collecting the head water level data of the power system and the current total load, and load-level reduction or supplementary adjustment decisions are performed according to different modes, including determining the calling strategy of non-critical areas and backup power supplies.

Benefits of technology

It realizes precise load adjustments based on the real-time status of the power system, avoids excessive adjustments, improves the stability and economy of the system, and ensures timely response when water level changes.

Abstract

The invention relates to the technical field of computers, and provides a rapid load adjustment decision method and system based on head water level prediction, and the method comprises the steps: collecting the head water level data and the current total load of a power system; determining a water level change mode based on the head water level change trend and the head water level change rate; the water level change mode comprises a rapid rising mode and a rapid falling mode; if the water level change mode is in a rapid rising mode, determining a non-critical area based on load information of each area associated with the power system, and executing a load grading reduction adjustment decision based on the non-critical area, the head water level change rate and the current total load; and if the water level change mode is in a rapid drop mode, a transferable load area and a standby power supply are obtained, and a load supplement adjustment decision is executed based on the head water level change rate, the current total load, the transferable load area and the standby power supply capacity of the standby power supply. According to the invention, the operation stability and economy of the power system are improved.
