A simple method for studying the influence of bus loads on power system transient stability

Transient stability is an important problem in power systems. The influence of bus loads on power system transient stability is one of the main concerns by operators. This problem is studied and a simple method for studying the influence of bus loads on transient stability is presented in this paper. It can avoid recomputing the new power flow and reforming the reduced admittance matrices. Furthermore, sensitivity analysis can be used to speed up transient stability assessment. Some simulation results and comparisons are given.
