| 摘要: |
| 随着风电渗透率日趋提高，大规模风电的接入对电网静态电压安全的影响也逐渐增强，风电出力分钟级的显著变化将导致电网运行状态的频繁波动，甚至出现静态电压失稳的可能。为应对该问题，提出考虑大规模风电接入的在线电网静态电压安全风险指标，并搭建基于此风险指标的预防控制模型以降低系统运行风险，提高系统稳定运行裕度。IEEE 9节点系统和IEEE 39节点系统验证了所提风险指标和预防控制模型的有效性。 |

| Abstract: |
| The impact of large-scale wind-power integration on the static voltage security of power system increases along with the increase of wind-power penetration rate, and the significant minute-level change of wind power often causes the operational state fluctuation of power system, even the static voltage instability, aiming at which, an online risk index of power-system static voltage security is proposed with the consideration of large-scale wind-power integration. A preventive control model based on this index is built to reduce the risk of system operation and improve the margin of stable system operation. IEEE 9-bus system and IEEE 39-bus system are applied to verify the effectiveness of the proposed risk index and preventive control model. |
