Characteristics of static voltage stability for distributed generation integrated into power system and its impacts analysis
摘要
Abstract
The integration of distributed generation relieves the pressure of environmental pollution and energy shortage, but at the same time it could bring new challenge to the grid safe operating analysis, particularly the variation of DG control strategies may complicate the static voltage stability analysis. The effect of integrating DG on static voltage stability mostly depends on the capacity and control strategies of DG. Firstly, the equivalent circuit of external grid of DG integrating line is implemented and the analytic expression of load voltage regard to the penetration of DG is derived, and on the basis, the load voltage and the PV characteristic is analyzed under different DG penetrations. Then the impact of the different reactive power control strategies on load PV characteristic is compared. At last, the extended line voltage stability index is used to study the effects of DG reactive power control strategies on the line voltage stability index.关键词
