Abstract

In certain situations, it is necessary to consider the use of an alternate control means to enhance and insure power system stability such as an emergency state control. A class of switchable supplementary controls, such as dynamic brakes, shunt reactor or series capacitors could be utilized. The contribution of this paper 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 closed-loop control. The control strategy is evaluated through the digital simulation of a two machine test system.
