Automatic generation control performance evaluation method for thermal power units based on improved linear segmentation method

The participation of thermal power units in deep peak regulation is of great significance to the improvement of power grid consumption capacity, but the network-related performance decreases under deep peak regulation. Combined with the requirements for the automatic generation control performance of thermal power units, an automatic generation control performance evaluation method for thermal power units based on improved linear segmentation method is proposed. The method automatically divides the response, action and stability stages in the process of variable load, and conducts dynamic performance analysis on the variable load process. Compared with the existing evaluation methods, the automatic generation control performance evaluation method based on the improved linear segmentation method is less affected by noise, and the evaluation results are more accurate.
