Dynamic Simulation & Analysis Of Wind-Diesel System For Isolated Area.

      Аннотация: Investigation of the voltage and frequency control of a wind diesel hybrid system with several diesel gensets and dump load with Simulink models and validation with some measurements on a real system. The wind power is just depending on the wind conditions. Hence, the diesel generation has to include the enough control in order to keep the permissible frequency and voltage limits and to verify the power balance at every moment. These two are the main points where the analysis must be focused on. Many simulations about these systems have already been done, but a possible extension can be including in the model several wind turbines and diesel gensets, which could work at the same time. That complicates the analysis due to the interaction among them, and even more when setting some different dynamic parameters on the diesel gensets, as the inertia values. Regarding to a real system with this performance, there are some additional difficulties that the system has got, just because it is operating as an isolated one: bigger voltages and frequency deviations; the smaller the electrical machines, the more important the saturation; etc.
