In this paper, a method of structural analysis and control of voltage stability in electric power system is proposed based on Generalized Tellegen's theorem. According to the change of power network topology structure, power network will be divided into fundamental network and derivative network. Because Generalized Tellegen's theorem can connect the network topological structure and parameter with...
A fast method for determining the static voltage stability of modern power systems with static var compensator (SVC) is proposed in this paper. Static var compensator is an important component of flexible AC transmission system, which provides an effective approach to enhance voltage stability and to increase the power transfer capability. This paper discusses the effect of SVC controller on voltage...
A variable interval fuzzy mutual control method with self-adjusting factor is proposed in the whole field, which is aimed at the given control object of unified power flow controller in this paper. Simulation result indicates that node voltage and line power flow are effectively controlled and the transient stability of power system is improved in the designed control system, besides response quickly,...
