A review of dynamic generator reduction methods for transient stability studies

Due to the complex interconnected nature of power system, aggregate or reduced system is commonly used by operators and engineers for various power system studies. Transient stability studies need dynamically reduced models to include the dynamic effects of the generating units. Dynamic generator reduction is therefore an important component of power system dynamic reduction. The many different methods for generator reduction in power systems taken from the earliest available literature are discussed. This paper aims to provide an easy reference to researchers interested in exploring dynamic reduction of power systems.
