为了满足大规模互联电力系统安全与经济协调优化的目标,在分析了一些不同混杂电力系统模型基础上,提出了混和逻辑动态(MLD mixed logic dynamic)电力系统模型,并利用分叉与拓扑理论,针对所设计混杂电力系统模型,探讨了能否以及如何利用非线性的分析方法分析所设计系统的稳定性。文章提出了一种混杂逻辑动态电力系统模型稳定性的分叉理论分析方法,并对此方法加以具体分析,从而得出分叉理论是考察混杂电力系统稳定性的一种有效方法,并展望了分叉理论在混杂系统研究的应用前景。

To satisfy the safe operation of large scale power system and its economic optimization, MLD hybrid system is adopted by analyzing different hybrid power systems. Meanwhile, by employing bifurcation and topological theories,it discusses if it is available and how to use the nonlinear method to analyze the stability of the designed system, which is applied to the hybrid systems. This paper puts forward a bifurcation analysis method considering stability of MLD hybrid power system. In addition, an analysis is detailed as well. The conclusion is that furcate analysis method is effective in respect of examing the stability of power system, and it also predicts the bifurcation of furcate theory in hybrid power systems.
