Abstract:	This paper aims to study the operation of a grid-connected low-voltage AC microgrid with multiple distributed generations (DGs). First of all, a 400 V low-voltage AC microgrid integrated with a 30 kW microturbine generator, a 13 kW photovoltaic generation system, a 10 kW fuel cell generation system, and a 10 kVA wind turbine generator was employed as the sample system. Next, a sequential three-phase power-flow program that developed by the implicit ZBUS Gauss method was derived in this paper. Finally, the daily transformer loadings, voltage profiles, line flow profiles, and system losses of the proposed microgrid were analyzed and discussed by the developed sequential three-phase power-flow program. The outcomes of this paper are helpful for engineers to realize the operation characteristics of AC low-voltage microgrids.
