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...
With the ever increasing demand for power, the complexity and the cost of transmitting extra high power over larger distances increases. Distributed generation provides a relief for the transmission losses by generating power nearby the load. This paper focuses on the effect of distributed generation on the quality of the system voltages at any concerned location due to various faults occurring on...
In power systems, superconducting fault current limiters (SFCL) emerge as an alternative to limit the prospective short circuit currents to lower levels. The purpose of this paper is to study the influence of using superconducting devices on the transient stability of the synchronic operation and power quality. Different SFCL design and local of installation are also analyzed. Simulation studies are...
