摘要：Automatic generation control (AGC) technology is an important technical to maintain balance between power generators and loads. As the proportion of new energy power generation increases, the grid has higher requirements for frequency stability, so an accurate AGC performance evaluation method is necessary. This paper establishes a model of thermal power unit, and the model considers the influence of primary frequency control. After the model established, the model parameters are calculated by the genetic algorithm. And the accuracy is obtained of the model by calculating the fit between the actual output and the model output. Then the AGC performance evaluation results are obtained through the established model. It can be seen from the industrial case that the proposed method can accurately calculate the AGC performance evaluation index. © 2019 IEEE.
