| 摘 要： | 为了解决风电接入电网带来的系统灵活性与风电消纳以及运行不稳定问题.文中提出了随机潮流下电压稳定L指标评价电压稳定与电网运行域的概念,该方法可以准确地找出风电并网后全网电压稳定性最薄弱的节点,帮助调度人员对薄弱节点监视与控制,并提出基于观测全网电压稳定情况的电网运行域划分指标,基于电压稳定约束将电网划分为不同的运行域.通过IEEE-30节点典型算例系统仿真计算,验证了所提策略与指标的有效性.

| Abstract: | The operational instability and scheduling complexity is brought by the high proportion of renewable energy access to the grid.This paper proposes a method based on the mean voltage stability L-index analysis of stochastic voltage stability and the grid operating domain.This method can quickly find the weakest node in the whole network and help the dispatchers monitor and control the weak nodes.Based on the observation of the voltage stability of the whole network,the grid operation domain division index is proposed,and the grid is divided into different operation domains based on the voltage stability constraint.The validity and correctness of the proposed scheme and indicators are verified by the typical example of IEEE-30 node. |

| Keywords: | Grid operating domain System flexibility Wind power consumption Static voltage stability |
