: This thesis deals with voltage drop characterization of transmission systems by using power electronics circuits supplied
from embedded generation.
Many grids connected power electronic systems, such as STATCOMs, UPFCs, and distributed generation system interfaces, used
voltage source inverters (VSI) connected to the supply network through a filter. This filter, typically a series inductance acts to
reduce the switch harmonics entering the distribution network an alternative filter is an LCL network, which can achieve reduced
levels of harmonic distortion at lower switching frequencies and with less inductance, and therefore has potential benefits for
higher power application. However, systems incorporating LCL filters require more complex control strategies
