Abstract
This paper presents a methodology for voltage sags magnitudes calculation in the presence of alternative energy sources and/or distributed generators. The method determines the degree of influence of the parameters from the new generating units connected to the electrical system with regard to voltage sags magnitudes. The impedance matrix - Zbus is used to obtain analytical expressions that represent key variables in the analysis of voltage sags caused by faults in the grid. The methodology is applicable to any network topology, from transmission to distribution and seems to be a very promising tool to estimate voltage sags in smart grids.
