摘要
为解决多机风电并网系统的稳定性问题,提出在风电并网系统的同步发电机(SG)中安装电力系统稳定器(PSS),利用差分进化算法解决SG中自动电压调节器(AVR)和PSS参数的最优调节问题。在有、无PSS以及是否使用差分进化法的各种情况下对风电并网系统稳定性进行了研究分析,研究表明通过差分进化法的协同调节使含AVR和PSS的风电并网系统有良好的阻尼作用,能减少发电机转子角差振荡,提高电压稳定性,通过仿真结果对比可知差分进化法可使并网系统稳定性明显提高。
In order to solve stability problem of multi-machine wind power integrated system, Power System Stabilizers (PSSs) are installed for Synchronous Generator(SG), using Differential Evolution(DE) algorithm to solve the optimal regulation problem of Automatic Voltage Regulator(AVR) and PSS parameters in SG. Under the situation of with or without PSS and whether using differential evolution algorithm, the stability of wind power integrated system is studied. The research shows that wind power integrated system has good damping effect by AVR-PSS coordinated tuning based on DE algorithm, can reduce oscillation of rotor angle difference and improve voltage stability. Simulation results show that the stability of wind power integrated system can be greatly improved through using the DE algorithm.
