Control Parameter Identification Method of Wind Power Grid-Connected Converter Based on Optimization Algorithm
摘要
Abstract
In order to maintain the consistency of parameters such as current,voltage,frequency,and phase during wind power grid connection,and to improve the safety and stability of wind power grid connection,a method for identifying control parameters of wind power grid connected converters based on optimization algorithms is proposed.The control model is established for the wind power grid connected converter,and the power control command of the PI(Proportional Integral)regulator is changed based on the power voltage support.Using differential function equations,to set the control conditions of the PI regulator,to calculate the functional relationship in the complex frequency domain,and to clarify the logical relationship between the adjustment integral coefficients.The identifiability of the control parameters is obtained through the control transfer function,and the parameter control output value and characteristic data are analyzed.Finally,the optimization and identification results of the control parameters are completed.The experimental results show that the proposed method can complete the identification of control parameters in various environments,with small identification error and high accuracy.关键词
