Economic operation real-time power generation dispatching and control method

Abstract

The invention provides an economic operation real-time power generation dispatching and control method. The method comprises a rolling plan, including the steps of obtaining a difference value between ultra-short-period power generation demand forecasting of a first time frame and a day-ahead plan; if the difference value is greater than a preset value domain, correcting a unit output value; if the difference value is less than or equal to the preset value domain, obtaining a difference value between the ultra-short-period power generation demand forecasting of the t+1 time frame and the day-ahead plan until the difference value is greater than the preset value domain, and correcting the unit output value, wherein t is an integer greater than 1; obtaining a difference value between the ultra-short-period power generation demand forecasting of the t+2 time frame and the last corrected value; and if the difference value is greater than the preset value domain, correcting the unit output value. According to the scheme, the real-time dispatching and control for the power generation system are realized based on the difference value between the ultra-short-period power generation demand forecasting and the day-ahead plan, so that human intervention is greatly reduced, the working efficiency of dispatchers and the dispatching accuracy are improved, and the problem of low real-time property and low accuracy of the power dispatching in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of electric power dispatching, in particular to a real-time generation dispatching and control method for economical operation. Background technique [0002] Power dispatching is an effective management method adopted to ensure the safe and stable operation of the power grid, reliable external power supply, and orderly progress of various power production tasks. The specific work content of power dispatching is based on the data information fed back by various information collection equipment, or the information provided by monitoring personnel, combined with the actual operating parameters of the power grid, such as voltage, current, frequency, load, etc., to comprehensively consider the development of various production tasks , judge the safety and economic operation status of the power grid, issue operation instructions through telephone or automatic system, and direct on-site operators or automatic control systems...
