Supplemental control strategies for the transient stability enhancement of multimachine power systems
The contribution of this research is in the area of multimachine control, and, in particular, a power system emergency state control. Topics concerning control models, optimization criteria and characteristics of supplementary controls have been addressed. Dynamic programming is used to derive a switching strategy which takes the form of a feedback control. Since an optimal switching strategy is difficult to implement, suboptimal switching strategies are also considered. Control strategies are evaluated through digital and analog simulation of one and two machine test systems as well as a full-scale ten machine test system. Methods for obtaining dynamic equivalents of groups of generators are used to reduce the number of variables necessary for calculating a control.
