| 摘要: |
| 针对光伏并网对系统小干扰稳定的影响，提出基于随机响应面法和摄动法的阻尼比灵敏度求取方法。以光伏出力波动的随机激励作为摄动量，通过摄动法求解光伏在不同节点并网的阻尼比灵敏度；根据阻尼比灵敏度的大小筛选最佳的光伏并网节点，通过优化方法确定光伏发电的接入位置和容量，得到光伏发电的最佳接入方式。以New England 10机39节点系统和西部某省实际电力系统为例验证所提方法的有效性。 |

| Abstract: |
| Aiming at the impact of photovoltaic integration on system small disturbance stability, a solving method of damping ratio sensitivity based on random response surface method and perturbation method is proposed. The random excitation of photovoltaic output fluctuation is taken as the perturbation, and the damping ratio sensitivities are solved with photovoltaic accessed to grid on different nodes by the perturbation method. The optimum photovoltaic accessed node is selected according to the damping ratio sensitivity, the access location and capacity of photovoltaic power generation are determined through optimization method, and the optimum access mode of photovoltaic power generation is obtained. New England 10-generator 39-bus system and an actual power system in a western province are taken for examples, which verifies the effectiveness of the proposed method. |
