ESA对DFIG风电场并网系统静态电压稳定性影响
Static voltage stability of power systems including wind farm equipped with DFIG based on ESA
摘要
Abstract
For the impact of integration of DFIG based wind farm on the static voltage stability of power systems, eigenvalue structure analysis (ESA) of Jacobian matrix is employed, and weak stability region under normal load and the instability region under limit load are provided by combining with the participation information of relative nodes and static stability margin of system. The simplified model of wind farm was applied for simulation and analysis in the standard IEEE test system with 10 machines and 39 nodes. The result of study shows that the integration of wind farm reduces the static stability margin and extends the weak stability region; the integration of wind farm decreases the system’s load margin, but it has no effects on the instability region and instability mode. Furthermore, with the output active power of wind farm decreasing, the participation factors of wind farm node increases, the static stability margin decreases, and wind farm node becomes a key node which impacts the system’s static voltage stability.关键词
