摘　　要：针对电力系统风电调峰问题,提出了一种灰色非线性PID控制方法。该调峰方法在水电为主要调峰资源前提下,利用灰色理论预测风电功率,实时计算出风电功率与额定功率值的偏差,作为调峰机组新的调节目标,将风电功率调节在一个计划值附近。不断调整PID增益参数,使其随着功率偏差的变化而变化,进一步提高其控制性能。仿真结果验证了该调峰方法的有效性。For wind power system peak load regulation issues,a grey nonlinear PID control method is proposed in this paper.Base on the premise that hydropower is the main peak load regulation resource,the method adopts grey theory to forecast wind power,and calculates instantaneously the power deviation from the rated value.As the new regulation target for generating units,the wind power will be regulated in the vicinity of a planned value.It constantly adjusts the PID gain parameters according to the changing power deviation,so that its control performance can be further improved.Finally,simulation results verify the validity of the method.
