Resumen:

Frequency stability is one of the most relevant issues in operation of isolated power systems. High penetration of renewals may affect significantly frequency stability of isolated power systems since wind and solar photovoltaic generation have neither inertia nor primary frequency regulation. An alternative is the use of storage systems in the most critical operating conditions in such a way that if a generator trips, storage systems are subsequently tripped and the power balance is restored. This paper presents an approach to determine the maximum renewable generation in an isolated power system to prevent non-admissible frequency excursions in case of generator tripping. Moreover, such approach allows sizing an energy storage system to increase tpenetration of renewals.
