AC Power Flow Analysis for Inverters in Microgrid Application

Abstract In a microgrid system, proper current distribution and load sharing strategies are essential to achieve reliable parallel operation. Line impedance is an important factor when implementing control technique for inverter operation, whether it operating in grid connected or island mode. It sometime difficult visualize the impact of different line power flow AC microgrid. this paper, inverter-based system common ac bus through purely resistive, inductive complex impedances investigated. For each case, effect inverter’s output voltage angle amplitude on active reactive studied. Several powers plots generated 3D surf system.
