Aspects Regarding the Use of Electronic Power Devices in Power Grid

Custom power devices are generally used to power sensitive consumers who need higher energy quality. This paper will exemplify some of the custom power devices used in distribution networks. The case study will highlight the solid-state current limiter effects on an electrical network by simulating a medium voltage network. By installing a solid-state current limiter, the value of the short-circuit current decreases; thus, the electrodynamic forces and thermal stresses supported by the components of the electrical network are reduced.
