Abstract

On-line dynamic security assessement is well-known from its industrial and academic value in the power community. The key problem for dynamic security assessment appears to be how to reduce the computational burden. It seems that no theoretically sound technique is available to this problem at the present. In this paper, some experimental results on dynamic security assessment through a fast integration method are reported. Emphasis is placed on two issues: choice of a better integration algorithm and exploitation of the use of an automatic contingency selection technique. A class of predictor-corrector algorithms of integration, which entirely fits the special configuration of the multi-machine classical model, is chosen in our study. An automatic contingency selection procedure which is physically rooted is proposed. The computer package is developed in a fashion that the sparsity of solution matrix/vector is fully explored. Simulation results of several test power systems are demonstrated. A comparison has been done between the proposed framework and energy function methods.
