Embodiment Construction
[0032] see figure 1 , This automatic power generation control system is characterized in that: it includes a data acquisition module sequentially connected to the power grid, a load forecasting model for each generator, and a load forecasting summary module connected to each load forecasting model, characterized in that: the above-mentioned load forecasting The summary module is connected with the signal of the optimization control module. The optimization control module receives the real-time data of the load in the power grid, and clusters and merges the results of each load prediction model in the automatic power generation control system. The result is used as a control curve, and the output track of the generator is optimized according to the curve, and an adjustment control signal is sent to each generator.
[0033] see figure 2 , the above-mentioned optimization control module includes the following functional modules.
[0034] Data receiving module: used to receive ...

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 an electric power system, in particular to an automatic power generation control system and an optimization method for automatic synthesis of load forecasting thereof. Background technique [0002] The automatic power generation control system of the power system is an important control system to ensure the safe and economical operation of the power system. It mainly controls and adjusts the unit output of each power plant in the power grid according to the change of the system load and according to the set optimization algorithm. [0003] It takes a certain amount of time for the generator set to respond to changes in load, and the output curve (or track) of the generator needs to be pre-set to make the system run in a safe and economical state. The key to determining the control optimization effect of the automatic power generation control system is to The gr...
