针对高渗透间歇性能源电网的薄弱节点识别问题,提出基于PV曲线有功负荷裕度和电压变化指标的综合分析方法。首先从有功负荷裕度角度机理分析间歇性能源电网静态电压稳定性的影响因素,在此基础上结合有功负荷裕度和电压变化指标识别电网的薄弱节点。以新疆某地区实际电网为例,验证了上述薄弱节点识别方法的有效性,同时通过PV曲线分析给出高渗透间歇性能源电网运行断面极限,对该电网运行提供一定借鉴。

英文摘要：

For the weak buses identification problem in the high permeability intermittent energy grid,a comprehensive analysis method is proposed which is based on the active load margin and voltage change index of PV curve. Firstly, the influence factors of the static voltage stability of power grid are analyzed from the point of active load margin. On the basis of this, the weak buses of the grid are identified by the comprehensive analysis of the active load margin and voltage change. And the effectiveness of the weak buses identification method is verified by the actual power grid in Xinjiang, at the same time, the operating section limit of the high-permeability intermittent energy grid is given through the PV curve analysis, which has some reference to the operation of the power grid.
