Abstract

This paper describes dynamic modeling of a microgrid operating in grid-connected mode. The model is applied to a distributed utility grid that uses three gas turbine based distributed generators (D.G.), generating power at distribution voltage level (415 volts) and these are connected to a MV grid through a transformer. These DGs are dynamic devices & hence affect the dynamic behavior of the distribution grid. The transient simulation in this paper is done using MATLAB SIMULINK. Analysis of the transient behavior of DGs in simulated environment is important for control of generators during faults, generator trip, surges and switching conditions
