摘要：
In this paper we investigate the impact of distributed generation (DG) on system stability using the trajectory sensitivity approach and identify the machines that are vulnerable to the addition of DG. We also vary the penetration level of DG and evaluate the influence of the DG modeling. Sensitivity formulation for the differential-algebraic equation model is presented through a single-machine infinite-bus (SMIB) example. The methodology can be extended to study the influence of parameters other than the clearing time, such as series line reactance. (c) 2008 Elsevier Ltd. All rights reserved.
