Network equivalents are used to reduce the size of electrical systems that can be difficult to solve due to computational constraints. They are also useful for cases in which it is sufficient to model in detail only a portion of the system that is relevant for the study to be performed. The purpose of this work is to apply Kron's reduction method in combination with frequency domain modeling techniques...
In contrast to the previous generation of power grid codes, recent standards require that distributed energy resources (DERs) provide low-voltage ride-through (LVRT) capabilities during grid faults. Consequently, the high penetration of DERs in today's power system requires an efficient method of controlling the active and reactive power of those resources during normal as well as abnormal voltage...
In this work, a general code is obtained to facilitate the simulation of the electromagnetic transient response of a transmission line excited by a nearby lightning stroke using EMTP-type programs, namely ATP (Alternative Transients Program) and PSCAD (Power Systems Computer Aided Design). Initially, a frequency domain model of a field-excited (illuminated) line is implemented using Taylor's formulation...
