Abstract

This undergraduate Project aims to compare electric power system linear models, mainly single machine-infinite bus (SMIB). The considered models are Heffron and Phillips (HPM), Power Sensitivity (PSM) and Current Sensitivity (CSM). The computational implementation will also be executed to use further in simulations. The HPM is a traditional model used on stability study of little perturbations of SMIB (deMello and Concordia, 1969; Larsen and Swann, 1981; Wang and Swift, 1996). The HPM expansion to multi machine systems has already been applied on the literature (Moussa, Yu, 1974; Chen, Hsu, 1987; MacLeod, 1992). The PSM is based on the active and reactive power balance in every bus of the system (Deckmann and da Costa, 1994; Freitas, 2006) and it is an alternative to the HPM. Its expansion to multi machine power system is already developed on the literature (da Costa, 1992; Freitas, 2006; Furini et al., 2011; Valle and Araujo, 2015; Menezes et al., 2016). The CSM has been used recently, which is based on the Kirchoff's nodal current law (Pádua Junior et al., 2013; Takahashi et al., 2013; Fortes et al., 2016). Considering that these models are linear, they can be used on the electric system performance faced to little perturbations by simulations. The computational implementation will use the MATLAB software. MATLAB is chosen due to be a powerful and easy platform. The obtained results will provide a better understanding of the problem and the conclusions will be discussed. This project is for one year. (AU)
