摘要
为了减少含大规模新能源电力系统运行过程中的煤耗和污染气体排放,引入差分进化算法,开展含大规模新能源电力系统频率协调控制方法设计研究.通过建立调速器和汽轮机传递函数,组成含大规模新能源电力系统频率控制模型.对模型进行有功功率平衡约束、频率偏差约束和设备运行约束.结合差分进化算法,实现电力系统互补互联协调控制.通过对比现有控制方法得出,新的协调控制方法应用后可以有效减少电力系统的煤耗和污染气体排放,达到更理想的运行效果.
Abstract
In order to reduce coal consumption and gaseous pollution emissions in the operation of large-scale new energy generation-integrated electric systems,this work made a preliminary attempt to employ the differential evolution algorithm into coordinated frequency control.The main efforts entailed were the modeling of frequency control by establis-hing the transfer functions between governor and steam turbine,the introductions of active power balance constraint,fre-quency deviation constraint,and equipment operation constraint to the model,and the realization of complementary,in-terconnected and coordinated control by combining the model with the differential evolution algorithm.The proposed method was indicated through comparative analysis to achieve effective reduction in coal consumption and gaseous pollution emission of the electric system compared with the existing methods.
