Examination of under frequency load shedding in smart grids

This paper has presented the analysis of smart grids´ power and frequency control. The spreading of the continuously increasing integration of the intelligent energy distribution networks is unavoidable. The regulatory options must be tested to the safe and long-term reliable operation. In the paper the model used for simulating the smart grid is introduced, and it is also shown, how to apply for examination of island operation. The results of the simulations are presented on a model network and the conclusions, that can also be drawn, are evaluated.
