The impedance of distribution lines within a microgrid significantly affects the performance of voltage regulation strategies because it determines the voltage drop along the lines and influences the effectiveness of voltage control devices. Distribution line impedance consists of resistance and reactance. Resistance causes voltage drops proportional to the active power flow, while reactance causes voltage drops proportional to the reactive power flow. High impedance lines result in larger voltage drops for the same amount of power flow, making it more difficult to maintain voltage within acceptable limits. This is especially problematic in microgrids with long distribution lines or radial configurations, where the voltage at the end of the line can be significantly lower than at the source. Voltage regulation strategies, such as using on-load tap changers (OLTCs), step voltage regulators (SVRs), or distributed generation (DG) units with voltage cont....
