Modelling interconnection of future combustion engine power plants with traditional grid

In this paper, a new simulation model is developed to be able to simulate diesel genset smart grid interconnection by keeping in view future requirements of the grids and grid codes. The simulations are carried out in Matlab/Simulink environment. An example case is based on 1200 kW variable speed diesel genset with permanent magnet synchronous generator (PMSG). The simulations are carried out for various dynamic behaviours of PMSG and their protection and control facilities, which are necessary in normal operating conditions and in a range of disturbed operating conditions in order to preserve or to re-establish system security. Various faults (e.g. disturbances) have been induced in the distribution system and the robustness of the network has been analysed to make sure continuous supply of electricity to the consumers in the future smart grid environment.
