为了提高大规模电力系统的整体稳定性，提出了一种基于序贯设计和全局优化的局部和广域控制器协调设计方法。采用序贯设计方法将分布式局部电力系统稳定器（LPSS）和高压直流（HVDC）广域稳定控制器（HVDC-WASC）分配到相应的阻尼模式。全局优化用于同时优化LPSS和HVDC-WASC的所有总体控制增益。建立了具有自适应搜索和更新主导振型能力的优化模型。线性分析和非线性仿真结果均验证了该设计方法在提高大规模电力系统稳定性方面的有效性。
A sequential design and global optimization method is proposed to coordinately design local and wide-area controllers to enhance the overall stability of large-scale power system. The sequential design is used to assign the distributed local power system stabilizer (LPSS) and high-voltage direct current (HVDC) wide-area stabilizing controller (HVDC-WASC) to the concerned damping modes. The global optimization is used to simultaneously optimize all the overall control gains of LPSSs and HVDC-WASC. Moreover, the optimization model, which has an adaptive ability of searching and updating dominant oscillation modes, is established. Both the linear analysis and nonlinear simulation results verify the effectiveness of the proposed design method in enhancing the stability of large-scale power systems.
