Dynamic simulation of fuel cells and microturbines integrated with a multimachine network

The paper discusses aspects of dynamic modelling and simulation of fuel cell and microturbine units as a part of a multi-machine electrical network. The focus is on the consideration of a large number of units connected to different low voltage nodes. In the study, the total power generated in decentralized units reaches up to 30% of the 110 kV network demands. Therefore, it is expected that decentralized sources impact the dynamic behaviour of the high voltage network and vice versa. Hence, the investigated power system comprises also the high voltage grid and the corresponding conventional power plants supplying into this network. To evaluate the performance of the network, various disturbances are applied and the results are discussed.
