An new approach to determine the margin of voltage stability region in power injection space (SVSR) for power system with wind farms is presented. The SVSR boundary is described by a set of hyper-planes, whose number and tangent point are determined by clustering method. The presented approach is validated by several power system. It can be revealed that the approach can be used for power system voltage...
A new approach to determining the local boundaries of voltage stability region in power injection space (IVSR) for power system with wind farms is presented. It can be used for power system voltage stability analysis and on-line security assessment with considering the output uncertainty of the wind farms. Firstly, power flow tracing and double dispatching are used to determine the generators that...
Development for a static voltage security assessment software package entitled power system voltage stability region (PSVSR) is presented in this paper. A novel power system stability analysis method named "security region" is utilized to develop this comprehensive software package. PSVSR has been implemented in standard C++ on Windows environment. It is constructed with three layers: user...
