摘要

提出一种抑制水风互补系统超低频振荡的控制参数协同优化方法。首先,采用转矩分析法,研究水电机组调速系统控制参数影响超低频振荡的灵敏度。然后,基于水风互补系统模型,分析风电频率控制参数对水电机组阻尼的影响。进一步,构建水风互补系统控制参数协同优化模型,引入二阶振荡粒子群算法优化水电机组调速器PID参数及风电频率控制的PD参数。最后,以改进的4机11节点测试系统仿真模型为例,对所提参数协同优化进行分析、验证,仿真结果表明采用所提方法优化后的控制参数能够有效抑制水风互补系统超低频振荡。

Abstract

A coordinated optimization method of control parameters for hydro-wind complementary systems is proposed to suppress ultra-low-frequency oscillations. Firstly, the sensitivity of ultra-low-frequency oscillations to the control parameters of the hydro turbine governor is analyzed using the torque analysis method. Then, based on a hydro-wind complementary system model, the impact of wind power frequency control parameters on the damping of hydro units is investigated. Furthermore, a coordinated optimization model of control parameters is developed, the second-order oscillatory particle swarm optimization algorithm is introduced to optimize the PID parameters of the hydro turbine governor and the PD parameters of wind power frequency control. Finally, the proposed coordinated optimization approach is analyzed and validated using an improved four-machine, eleven-bus test system. Simulation results demonstrate that the optimized control parameters effectively suppress ultra-low-frequency oscillations in the hydro-wind complementary system.
