Based on the basic concepts and the main methods of bifurcation theory, we introduce the dynamic bifurcation Phenomenon in the power system voltage stability analysis and the relationship between them, making a more comprehensive summary and comment about dynamic bifurcation which used in the power system voltage stability analysis currently. In the text, we discuss the Hopf bifurcation (HB), period-doubling...
Multiple voltage stability incidents show that system dynamic components have a great impact on voltage stability. This article mainly analyzes and summarizes the impaction on voltage stability based on the bifurcation theory caused by dynamic characteristics of main components in the power system such as load characteristics, generator characteristics, OLTC and Static Var Compensator (SVC).It Proposes...
It is a challenge and prospect’s field of power system voltage stability analysis by using bifurcation theory. In this paper, difference of control parameters in bifurcation analysis is used as the main line, and then the features and research of SNB, Hopf as well as other kinds of bifurcations in single and two-parameter bifurcation analysis are introduced. At last, on the basis of discussion, a...
The stability of wind power systems is becoming a hot research with the expansion of the total installed capacity of wind power; wind speed model is of great significance in dynamic stability analysis of wind power systems. In this paper, taking into account the random and uncontrollable nature of wind speed variations, wind speed model research status at home and abroad is summarized from different...
