Automatic electricity generation control system and load prediction automatic integrated optimization method

Abstract

The invention relates to an automatic electric-power generation control system and an optimization method thereof for load prediction automatic synthesis. The method comprises the following steps: step 1, more than three load prediction results are added to a result queue one by one; step 2, the distance between every two load prediction results in the queue is calculated; step 3, the two load prediction results with the closest distance are taken as the new results added to the queue in average, and meanwhile, the two results are deleted from the queue; step 4, the load prediction result number in the queue is detected, if the number is more than 3, the step 2 is returned, and if the number is equal to three, the step 5 is continued; step 5, the load prediction results in the queue are arranged from high to low; and step 6, the results arranged in the middle are loaded in the automatic electric-power generation control system and used for adjusting and optimizing the output of the electric generator; and the output of the machine sets of all the electric power plants in the electric network is further optimized, the power supply cost is reduced, the load prediction precision in the automatic electric-power generation control system is enhanced, and the load prediction error is reduced.

Description

Technical field [0001] The invention relates to a control method of an automatic power generation control system of a power system, in particular to an automatic power generation control system and an optimization method for automatic synthesis of load forecasting. Background technique [0002] The automatic power generation control system of the power system is an important control system to ensure the safe and economic operation of the power system. It mainly controls and adjusts the output of the units of the power plants in the power grid according to the changes of the system load and the set optimization algorithm. [0003] It takes a certain amount of time for the generator set to respond to changes in load. The generator output curve (or track) needs to be set in advance to make the system run in a safe and economical state. Therefore, the key to determining the control optimization effect of the automatic power generation control system is to correct The grasp of system ...
