This paper presents dynamic models of distributed generators (DG) and investigates
dynamic behaviour of the DG units within a microgrid system. The DG units include micro
turbine, fuel cell and the electronically interfaced sources. The voltage source converter is
adopted as the electronic interface which is equipped with its controller to maintain
stability of the microgrid during small signal dynamics. This paper also introduces power
management strategies and implements the DG load sharing concept to maintain the
microgrid operation in standalone, grid-connected and islanding modes of operation. The
results demonstrate the operation and performance of the microturbine and SOFC as
distributed generators in a microgrid.
