基于双层规划的非线性鲁棒电力系统稳定器参数整定方法
A Bilevel Programming Based Method for Tuning Parameters of Nonlinear Robust Power System Stabilizer
摘要
Abstract
Using the advanced control methods in generator excitation systems is an effective measure to improve the static and dynamic performance of power systems.The nonlinear robust power system stabilizer (NR-PSS) designed by feedback linearization and robust control is an advanced excitation control device.On the basis of an in-depth study on the principles of power system stabilizer (PSS) parameter adjustment and the existing methods of NR-PSS parameter tuning,a bi-level optimization based method is proposed for determining the parameters of the linear part of NR-PSS to meet the requirements of two aspects,namely,wider damping band and lower control costs.The optimal parameters are obtained through an equivalent nonlinear program.Numerical simulation results show that with the optimal parameters provided by the presented method,the control performance of NR-PSS is improved.
