Recent experience shows that this increase of power generation sources influences the behaviour of grid connected generating units. One observation is the change in the generated power after a transient disturbance especially its oscillatory behaviour accompanied by similar oscillatory behaviour of the grid frequency. An understanding of such behaviour of generators under various disturbances requires a new modelling technique. Therefore, a mathematical model of a generating station based on a system of coupled nonlinear differential equations and suitable for analysis of its stability is presented. The mathematical model will allow one to highlight limitations to the operational range of synchronous generators and could also be used to identify limits to the amount of total inertia necessary to maximise the usage of grid connected non-synchronous generators such as wind turbines and solar photo-voltaic installations.
